The Siemens 5SU1354-1RC20 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 is specified as a 20 A, 2-pole / 1P+N, 2-module, C-characteristic, Type AC, 30 mA RCBO with a 240 V AC rated supply voltage. Its technical data specifies a 10 kA short-circuit breaking capacity according to EN 61009-1, 20 kA according to IEC 60947-2, and 10 kA rated residual switching capacity.
The 5SU1354-1RC20 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 construction can simplify circuit-level protection and reduce the need for separate MCB and RCCB devices.
The exact product listing identifies the article as 20 A, 2-pole, 2-module, C characteristic, Type AC and 30 mA.
The 5SU1354-1RC20 has a rated current of 20 A.
This makes it suitable for compatible single-phase circuits designed around a 20 A protective device. The actual selection should consider cable capacity, connected load, installation method, ambient conditions and applicable electrical regulations.
The exact Siemens data specifies 20 A operational current.
The RCBO uses a C tripping characteristic.
The C curve is intended for compatible circuits where normal operation can involve moderate starting or inrush currents.
Potential applications include:
Pumps
Fans
Small motors
Contactors
Solenoids
Control transformers
Industrial auxiliary equipment
Selected electrical equipment
The exact Siemens product data confirms the C tripping characteristic.
The 5SU1354-1RC20 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 considered before selecting Type AC. Equipment capable of producing pulsating DC or other residual-current components may require a different residual-current type.
The exact product data confirms Type AC residual-current protection.
The 5SU1354-1RC20 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 installation requirements. The exact technical data confirms 30 mA rated tripping fault current.
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
The exact Siemens technical data specifies a 240 V AC supply voltage and 50 Hz operating frequency.
This makes the device suitable for compatible single-phase AC distribution systems within its specified ratings.
The 5SU1354-1RC20 has a 10 kA short-circuit breaking capacity according to EN 61009-1. The technical data additionally lists 10 kA according to EN 60898, 20 kA according to IEC 60947-2, and 10 kA rated residual switching capacity according to IEC 61009-1.
The prospective short-circuit current at the installation point should still be checked during system design.
The exact technical data specifies energy limitation class 3.
This characteristic is relevant when evaluating the device's response to short-circuit energy within its applicable standards and installation conditions.
The 5SU1354-1RC20 is a 2-module RCBO.
Siemens specifies 2 modular width units and a physical width of 36 mm.
This compact design is useful where 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 width and does not represent a power rating.
The Siemens 5SU1 RCBO family is designed for modular electrical installation.
The 5SU1354-1RC20 can be integrated into compatible distribution boards and electrical panels alongside other DIN-mounted protection and control components.
The technical data specifies the mounting position as any, subject to the manufacturer's installation requirements.
The overcurrent section of the RCBO protects the connected circuit against sustained excessive current caused by overload.
The 20 A rated current should be coordinated with:
Cable ampacity
Connected load
Installation method
Ambient temperature
Protection requirements
Correct selection helps protect the circuit while minimizing nuisance tripping.
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 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.
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 selection should be evaluated according to the load's starting-current characteristics.
The 5SU1354-1RC20 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.
The 5SU1354-1RC20 can be considered for compatible:
Commercial distribution boards
Building electrical panels
Office circuits
Equipment feeders
Industrial auxiliary circuits
Control-panel supplies
Single-phase equipment
Dedicated electrical circuits
The final application should follow the electrical design and applicable standards.
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
The technical data specifies that the power-supply connection can be made from either the top or bottom.
This provides practical flexibility during panel wiring and installation.
The exact 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.
The technical data specifies:
Operating ambient temperature: -5 °C to +45 °C
Storage ambient temperature: -40 °C to +75 °C
Maximum relative humidity: 95%
These conditions should be considered when selecting the installation location.
The supplied Siemens product designation states that the device is permitted in all countries and instructs users to observe national installation regulations.
For installations in India, applicable Indian electrical installation requirements and the manufacturer's installation instructions should be followed.
The 5SU1354-1RC16 is the corresponding 16 A, 2-pole, 2-module, C-characteristic, Type AC, 30 mA RCBO.
Therefore:
5SU1354-1RC16 → 16 A
5SU1354-1RC20 → 20 A
The main difference is the rated current.
The 5SU1354-1RC25 is the corresponding 25 A, 2-pole, 2-module, C-characteristic, Type AC, 30 mA RCBO.
Therefore:
5SU1354-1RC20 → 20 A
5SU1354-1RC25 → 25 A
The main difference is the rated current.
The 5SU1354-1RC32 is the corresponding 32 A, 2-pole, 2-module, C-characteristic, Type AC, 30 mA RCBO.
Therefore:
5SU1354-1RC20 → 20 A
5SU1354-1RC32 → 32 A
The correct current rating should be selected according to the protected circuit and conductor capacity.
The 5SU1354-1RC40 is the corresponding 40 A, 2-pole, 2-module, C-characteristic, Type AC, 30 mA RCBO.
Therefore:
5SU1354-1RC20 → 20 A
5SU1354-1RC40 → 40 A
The main difference is the rated current.
The 5SU1354-7RC20 belongs to the Type A version of the 5SU1 RCBO family, while 5SU1354-1RC20 is specifically Type AC.
Therefore:
5SU1354-1RC20 → Type AC, 20 A, 30 mA
5SU1354-7RC20 → Type A, 20 A, 30 mA
The main difference is the residual-current type.
The 5SU1654-1RC20 belongs to the higher residual-current sensitivity configuration.
Therefore:
5SU1354-1RC20 → 20 A, Type AC, 30 mA
5SU1654-1RC20 → 20 A, Type AC, 300 mA
The principal difference is the residual-current operating threshold.
The 5SU1354-1RC20 is an RCBO, not simply an RCCB.
An RCCB primarily provides residual-current protection and normally requires separate overcurrent protection.
An RCBO combines:
Residual-current protection + overload protection + short-circuit protection
in one device.
