The Siemens 5SU1354-1RC32 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 Siemens data identifies it as a 32 A, 2-pole / 1P+N, 2-module, C-characteristic, Type AC, 30 mA RCBO with a 240 V AC supply rating and 10 kA short-circuit breaking capacity according to EN 61009-1.

Siemens 5SU1354-1RC32 RCBO

The 5SU1354-1RC32 belongs to the Siemens SENTRON / Betagard 5SU1 RCBO family. Unlike a conventional RCCB, an RCBO combines multiple protective functions in a single 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.

Siemens' product documentation lists 5SU1354-1RC32 within the 5SU1 Type AC RCBO range.

32 A Rated Current

The RCBO has a rated current of 32 A.

This makes it suitable for compatible single-phase circuits and feeders designed around a 32 A protective device.

The final selection should consider cable capacity, connected load, installation method, ambient temperature and applicable electrical regulations.

C Tripping Characteristic

The 5SU1354-1RC32 uses a C tripping characteristic.

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

Potential applications include:

• Pumps

• Fans

• Small motors

• Control transformers

• Contactors

• Solenoids

• Industrial auxiliary equipment

• Selected electrical equipment

The actual tripping characteristic should be matched to the load and protection-coordination requirements.

Type AC Residual Current Protection

The device uses Type AC residual-current protection.

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

The residual-current waveform of the connected equipment should be considered before selecting Type AC. Equipment capable of producing pulsating DC or other residual-current components may require a different residual-current protection type.

The exact Siemens data confirms the residual-current type as AC.

30 mA Residual Current Sensitivity

The 5SU1354-1RC32 has a rated residual operating current of 30 mA.

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

The 30 mA sensitivity should be selected according to the complete electrical protection design and applicable installation requirements.

Siemens' exact product data confirms 30 mA residual-current sensitivity.

2-Pole / 1P+N Configuration

The device has 2 poles in a 1P+N configuration.

This makes it suitable for compatible single-phase circuits where phase and neutral are incorporated into the switching/protection arrangement.

Typical applications include:

• Single-phase distribution boards

• Commercial electrical panels

• Building electrical systems

• Equipment feeders

• Office circuits

• Industrial auxiliary supplies

• Control-panel circuits

The exact Siemens data specifies 2 poles, 1 protected pole and 1P+N configuration.

240 V AC Application

The exact product data specifies a 240 V AC supply voltage and 50 Hz operating frequency.

This makes the article suitable for compatible single-phase AC distribution systems within its specified electrical ratings.

10 kA Short-Circuit Breaking Capacity

The 5SU1354-1RC32 has a 10 kA short-circuit breaking capacity according to EN 61009-1.

The technical data also specifies:

• 10 kA according to EN 60898

• 15 kA according to IEC 60947-2

• 10 kA rated residual switching capacity according to IEC 61009-1

• Energy limitation class 3

The prospective short-circuit current at the installation point should still be checked during system design.

Combined Overcurrent and Residual-Current Protection

The main advantage of the 5SU1354-1RC32 is the integration of multiple protection functions.

A conventional circuit may use:

MCB + RCCB

An RCBO combines these functions:

RCBO = Overload + Short Circuit + Residual Current Protection

This can simplify panel architecture and provide dedicated circuit-level protection.

Compact 2-Module Design

The exact Siemens data specifies 2 modular width units and a physical width of 36 mm.

The compact 2-module design is suitable for:

• DIN-rail distribution boards

• Commercial panels

• Control panels

• Sub-distribution boards

• Industrial electrical enclosures

The 2-module designation refers to physical panel space and does not represent a power rating.

DIN-Rail / Modular Installation

The Siemens 5SU1 family is designed for modular electrical-panel installation.

The 5SU1354-1RC32 can be integrated into compatible distribution boards and electrical panels alongside other DIN-mounted protection and control components.

The exact installation should follow Siemens' wiring and mounting instructions as well as applicable national installation regulations.

Overload Protection

The RCBO's overcurrent section protects the connected circuit against sustained excessive current caused by overload.

The 32 A rated current should be coordinated with:

• Cable ampacity

• Load current

• Installation method

• Ambient temperature

• Protection requirements

Correct coordination helps protect the circuit while minimizing nuisance tripping.

Short-Circuit Protection

The RCBO also provides integrated short-circuit protection.

Its 10 kA EN 61009-1 breaking capacity should be considered against the prospective fault current at the installation point.

Residual-Current Protection

Residual current occurs when part of the electrical current flows through an unintended path, such as leakage to earth.

The RCBO monitors this condition and disconnects the protected circuit when the residual-current operating threshold reaches 30 mA.

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

• Solenoids

• Contactors

• Control transformers

• Industrial auxiliary equipment

• Selected commercial equipment

The final application should be evaluated according to load starting characteristics.

Type AC Load Compatibility

The 5SU1354-1RC32 is intended for compatible sinusoidal AC residual currents.

For modern electronic equipment containing rectifiers, variable-speed drives or other power electronics, the required residual-current type should be checked before selecting Type AC.

Single-Phase Electrical Applications

The 5SU1354-1RC32 can be considered for compatible:

• Commercial distribution boards

• Building electrical panels

• Office circuits

• Equipment feeders

• Industrial auxiliary circuits

• Control-panel supplies

• Single-phase machinery

• Dedicated electrical circuits

The final application should follow the electrical 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

• 30 mA residual-current sensitivity

• Upstream protection

• Applicable electrical standards

Touch Protection and Power-Supply Connection

The Siemens data specifies IP20 protection when installed in a suitable distribution board with connected conductors. It also specifies that the power supply can be connected from either the top or bottom.

This provides practical flexibility during panel wiring while maintaining the required enclosure protection.

Environmental Conditions

The technical data specifies an operating ambient temperature range of -5 °C to +45 °C and a storage range of -40 °C to +75 °C. Maximum relative humidity is specified at 95%.

These conditions should be considered when installing the device inside electrical panels or distribution boards.

Permitted Countries and National Regulations

The supplied Siemens product designation explicitly states that the device is permitted in all countries, while also requiring users to observe national installation regulations.

For an India installation, the applicable Indian electrical installation requirements and the manufacturer's installation instructions should therefore be followed.
