Siemens 5SU1354-1RC16 RCBO

The 5SU1354-1RC16 belongs to the Siemens SENTRON / Betagard 5SU1 RCBO family. Unlike a conventional RCCB, an RCBO combines multiple protective functions in one device:

• Overload protection

• Short-circuit protection

• Residual-current protection

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

Siemens documentation lists 5SU1354-1RC16 within the 5SU1 RCBO range.

16 A Rated Current

The RCBO has a rated current of 16 A.

This makes it suitable for compatible single-phase circuits designed around a 16 A protective device. Final selection should consider the cable capacity, connected load, installation method, ambient temperature and applicable installation requirements.

The exact product data confirms the 16 A operational current at the AC rated value.

C Tripping Characteristic

The 5SU1354-1RC16 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

• Contactors

• Solenoids

• Control transformers

• Industrial auxiliary equipment

• Selected electrical equipment

The actual tripping characteristic should be selected according to load behaviour and protection coordination. The exact data identifies the device as C characteristic.

Type AC Residual Current Protection

The device uses Type AC residual-current protection.

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

The leakage-current waveform of the connected equipment should be checked 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 residual current type AC.

30 mA Residual Current Sensitivity

The 5SU1354-1RC16 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 overall electrical protection design and applicable national requirements.

The exact product data confirms the 30 mA rated tripping fault current.

2-Pole / 1P+N Configuration

The device has 2 poles in a 1P+N configuration, with 1 protected pole.

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

• Office circuits

• Equipment feeders

• Industrial auxiliary circuits

• Control-panel supplies

240 V AC Application

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

10 kA Short-Circuit Breaking Capacity

The 5SU1354-1RC16 has a 10 kA short-circuit current breaking capacity according to EN 61009-1.

The technical data also specifies:

• 10 kA according to EN 60898

• 20 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.

Energy Limitation Class 3

The exact technical data specifies energy limitation class 3.

This characteristic is relevant when evaluating the RCBO's behaviour under short-circuit conditions within the applicable standard and installation arrangement.

Compact 2-Module Design

The product is specified as a 2-module RCBO.

Siemens' data gives a physical width of 36 mm and 2 modular width units.

This compact format is useful where electrical-panel space is limited, including:

• 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 indicate a power rating.

DIN-Rail / Modular Installation

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

The 5SU1354-1RC16 can be integrated into compatible distribution boards and electrical panels alongside other DIN-mounted protective and control components.

The exact mounting arrangement should follow Siemens installation instructions and applicable national electrical regulations.

Overload Protection

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

The 16 A rated current should be coordinated with:

• Cable ampacity

• Connected load

• Installation method

• Ambient temperature

• Protection requirements

Correct coordination helps protect the circuit while minimizing unwanted 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 actual application should be evaluated according to the load's starting-current characteristics.

Type AC Load Compatibility

The 5SU1354-1RC16 is intended for compatible sinusoidal AC residual currents.

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

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 national installation regulations

Power-Supply Connection

The exact technical data specifies that the power-supply connection can be made from either the top or bottom.

This gives practical flexibility during electrical-panel wiring and installation.

IP20 Protection

The technical data specifies IP20 when the distribution board is installed with connected conductors.

The RCBO should therefore be installed within a suitable electrical enclosure or distribution assembly.

Environmental Conditions

The exact product data specifies:

• Operating ambient temperature: -5 °C to +45 °C

• Storage temperature: -40 °C to +75 °C

• Maximum relative humidity: 95%
