The Siemens 5SU1424-1RC63 is a SENTRON / Betagard 5SU1 Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to combine overload, short-circuit and residual-current protection in one compact device. The exact product listing identifies it as a 63 A, 2-pole, 4-module, C-characteristic, Type AC, 100 mA RCBO. Siemens product information and Indian listings confirm the 63 A current rating, 2-pole configuration, Type AC protection, 100 mA sensitivity and C characteristic.

Siemens 5SU1424-1RC63 RCBO

The 5SU1424-1RC63 belongs to the Siemens SENTRON / Betagard 5SU1 RCBO family. Unlike a conventional RCCB, an RCBO combines several protective functions in one device:

• Overload protection

• Short-circuit protection

• Residual-current protection

This integrated construction can simplify circuit-level protection and reduce the need for separate MCB and RCCB devices.

The exact article is listed with a 63 A rating, 2 poles, 4-module width, C tripping characteristic, Type AC residual-current protection and 100 mA residual-current sensitivity.

63 A Rated Current

The 5SU1424-1RC63 has a rated current of 63 A.

This makes it suitable for compatible higher-current single-phase circuits and feeders where the electrical protection design requires a 63 A protective device.

The final selection should consider:

• Connected load

• Cable ampacity

• Installation method

• Ambient conditions

• Prospective short-circuit current

• Protection coordination requirements

The exact product listing confirms the 63 A rating.

C Tripping Characteristic

The RCBO uses a C tripping characteristic.

The C curve is intended for compatible circuits where normal operation may involve moderate starting or inrush current.

Potential applications include:

• Pumps

• Fans

• Small motors

• Control transformers

• Contactors

• Solenoids

• Industrial auxiliary equipment

• Selected equipment feeders

The C characteristic should be selected according to the actual load and protection-coordination requirements.

The exact article is identified with a C curve.

Type AC Residual Current Protection

The 5SU1424-1RC63 uses Type AC residual-current protection.

Type AC protection is intended for compatible sinusoidal alternating residual currents.

The actual leakage-current waveform of the connected equipment should be considered before selecting the RCBO. Equipment capable of producing pulsating DC or other residual-current components may require another residual-current type.

The exact product is identified as Type AC.

100 mA Residual Current Sensitivity

The 5SU1424-1RC63 has a rated residual operating current of 100 mA.

When the residual-current condition reaches the specified operating threshold, the RCBO disconnects the protected circuit.

The 100 mA sensitivity should be selected according to the complete electrical protection design. It should not automatically be replaced by a 30 mA or 300 mA device because these are different protection configurations.

Indian product specifications confirm 100 mA residual-current sensitivity for this exact article.

2-Pole Configuration

The device has 2 poles and is intended for compatible single-phase applications.

The two-pole arrangement allows the phase and neutral circuit arrangement to be incorporated into the protection system according to the manufacturer's wiring configuration.

Typical applications include:

• Single-phase distribution boards

• Commercial electrical panels

• Building electrical systems

• Equipment feeders

• Office circuits

• Industrial auxiliary supplies

• Control-panel circuits

240 V AC Application

Indian product information for the exact 5SU14241RC63 identifies the rated voltage as 240 V AC.

This makes the device suitable for compatible single-phase low-voltage distribution systems where the voltage and protection requirements match the device.

The exact installation voltage should always be checked against the latest Siemens documentation and the electrical-system design.

10 kA Short-Circuit Breaking Capacity

The exact article is listed with a 10 kA breaking capacity.

The prospective short-circuit current at the installation point should nevertheless be assessed during system design, together with upstream protection and coordination requirements.

Because the device is an RCBO, its overcurrent section also provides short-circuit protection within its specified ratings.

4-Module Design

The product designation specifies 4 modules.

The 4-module designation refers to physical panel space and does not indicate a 4 MW power rating.

Indian product data identifies the exact article as a 4-module, 2-pole RCBO.

This format is suitable for:

• DIN-rail distribution boards

• Commercial panels

• Sub-distribution boards

• Control panels

• Industrial electrical enclosures

DIN-Rail Installation

The Betagard 5SU1 family is designed for modular electrical installation.

The 5SU1424-1RC63 can be integrated into suitable electrical distribution assemblies alongside compatible protective and control devices.

The panel should provide sufficient space and appropriate mounting arrangements for the device.

Overload Protection

The overcurrent section of the RCBO protects the connected circuit against sustained excessive current.

The 63 A rating should be coordinated with:

• Cable ampacity

• Load current

• Installation method

• Ambient temperature

• Protection requirements

Correct selection helps protect the circuit without unnecessary nuisance tripping.

Short-Circuit Protection

The RCBO also provides integrated short-circuit protection.

The specified 10 kA breaking capacity should be evaluated against the prospective fault current at the installation point.

The complete electrical protection system should be designed according to applicable standards and installation requirements.

Residual-Current Protection

Residual current occurs when a portion of electrical current flows through an unintended path, such as an earth-leakage route.

The RCBO monitors the residual-current condition and disconnects the circuit when the specified 100 mA threshold is reached.

This adds residual-current protection to the integrated overload and short-circuit functions.

C-Curve Applications

The C characteristic can be suitable for compatible loads with moderate inrush current.

Potential applications include:

• Pumps

• Fans

• Small motors

• Transformers

• Solenoids

• Contactors

• Industrial auxiliary equipment

• Selected commercial equipment

The actual selection should be based on load starting characteristics and protection coordination.

Type AC Load Compatibility

Type AC protection is intended for compatible sinusoidal AC residual currents.

The 5SU1424-1RC63 should therefore be selected where the connected equipment is compatible with Type AC residual-current detection.

For modern electronic equipment, the leakage-current waveform should be evaluated before selecting Type AC instead of Type A, Type F or Type B protection.

Single-Phase Applications

The 5SU1424-1RC63 can be considered for compatible:

• Commercial distribution boards

• Building electrical panels

• Equipment feeders

• Office circuits

• Industrial auxiliary circuits

• Control-panel supplies

• Single-phase equipment

• Dedicated electrical feeders

The final application should follow the electrical-system design and applicable regulations.

Protection Coordination

A typical arrangement can be:

Incoming Supply → RCBO → Protected Single-Phase Load

The complete protection design should consider:

• Prospective short-circuit current

• Cable capacity

• Load current

• C-curve characteristics

• 100 mA residual-current sensitivity

• Upstream protection

• Applicable electrical standards

Maintenance and Testing

RCBOs should be included in the electrical installation's regular inspection and testing program.

The device test function should be operated according to Siemens' instructions and applicable maintenance requirements to verify residual-current protection.

Regular testing helps confirm that the protective mechanism remains operational.

Installation Considerations

Before selecting the 5SU1424-1RC63, verify:

• Rated current: 63 A

• Residual-current sensitivity: 100 mA

• Residual-current type: Type AC

• Tripping characteristic: C

• Pole configuration: 2-pole

• Rated voltage: 240 V AC

• Short-circuit breaking capacity: 10 kA

• Required panel space: 4 modules

• Cable size and installation method

• Load inrush characteristics

• Applicable electrical regulations

Difference from 300 mA Version

The corresponding 5SU1624-1RC63 is the 63 A, 2-pole, 4-module, C-characteristic, Type AC, 300 mA configuration.

Therefore:

5SU1424-1RC63 → 63 A, 100 mA

5SU1624-1RC63 → 63 A, 300 mA

The main difference is the residual-current operating threshold.

Difference from 30 mA Version

The 5SU1424-1RC63 is specifically a 100 mA RCBO.

A 30 mA variant is a different product configuration and should not be treated as an exact replacement without checking the circuit protection requirements.

Difference from Type A Version

The exact Type AC article is 5SU1424-1RC63, whereas Type A variants use a different article configuration.

Therefore:

5SU1424-1RC63 → Type AC, 63 A, 100 mA, C

The residual-current type should be selected according to the connected equipment and its leakage-current waveform.

Difference from D Characteristic

The C characteristic is intended for compatible circuits with moderate inrush current.

A D-characteristic RCBO is intended for compatible circuits with higher starting or inrush currents.

The 5SU1424-1RC63 should therefore be selected specifically where the C characteristic is appropriate.

Difference from 40 A Version

The 5SU1424-1RC40 is the corresponding 40 A, 2-pole, 4-module, Type AC, 100 mA, C-characteristic RCBO.

Therefore:

5SU1424-1RC40 → 40 A

5SU1424-1RC63 → 63 A

The main difference is the rated current.

Difference from 32 A Version

The corresponding 32 A variant has a lower rated current while retaining the relevant Type AC, C-characteristic and 100 mA configuration.

The correct rated current should be selected according to the protected circuit and cable design.

Difference from 4-Pole Version

The 5SU1444 family contains four-pole RCBOs for compatible three-phase-plus-neutral systems.

The 5SU1424-1RC63 is a 2-pole RCBO for compatible single-phase applications.

Pole configuration should therefore be checked carefully before selecting a replacement.

Difference Between RCBO and RCCB

The 5SU1424-1RC63 is an RCBO, not simply an RCCB.

An RCCB mainly provides residual-current protection and normally requires separate overcurrent protection.

An RCBO combines:

Residual-current protection + overload protection + short-circuit protection

in one device.
