Siemens 5SU1324-7FP25 is a SENTRON RCBO designed to combine residual current protection and miniature circuit breaker functionality within a compact two-pole device. Rated at 25 A with a C tripping characteristic, it is intended for AC circuits operating at 230/240 V and 50 Hz, providing protection against overloads, short circuits and residual currents.
This Type A instantaneous RCBO has a rated residual current of 30 mA and a short-circuit breaking capacity of 10 kA according to EN 61009-1, making it suitable for use in distribution boards across commercial, industrial and building electrical installations. Its two-module width, IP20 protection rating when installed with connected conductors, and flexible supply connection from either the top or bottom support straightforward panel integration.
The 5SU1324-7FP25 features screw-type terminals accepting solid, stranded and finely stranded conductors from 1 mm² to 35 mm², with a tightening torque of 2 N·m. With a typical mechanical service life of 10,000 operating cycles, overvoltage category III rating and pollution degree 3 classification, this Siemens RCBO is built for dependable circuit protection in low-voltage electrical systems.

What type of electrical component is this?
This is an RCBO, combining residual current protection and overcurrent protection in one two-pole device. It is designed for AC circuits where both earth fault protection and circuit breaker functionality are required.
What current rating does it have?
The device is rated at 25 A at 30 °C. Its operational current is derated at higher ambient temperatures, for example 24 A at 40 °C, 23 A at 50 °C and 21 A at 70 °C.
What residual current sensitivity does it provide?
It provides 30 mA residual current sensitivity, making it suitable for circuits where additional protection against residual current faults is required.
What tripping characteristic does this RCBO use?
It uses a Type C tripping characteristic. Type C devices are commonly selected for circuits with moderate inrush currents, such as lighting groups, small motors and general distribution applications.
How many poles does the device have?
It is a 2-pole RCBO with protection on both poles. The device is intended for 230/240 V AC circuits operating at 50 Hz.
What is the short-circuit breaking capacity?
The short-circuit current breaking capacity is 10 kA according to EN 61009-1. The switching capacity is also listed as 10 kA according to EN 60898 and 15 kA according to IEC 60947-2.
What type of residual current detection is used?
This model is Type A, which means it is designed to detect residual sinusoidal AC currents and pulsating DC residual currents.
What are the device dimensions?
The 5SU1324-7FP25 measures 85 mm high, 36 mm wide and 72 mm deep, with an installation depth of 70 mm. It occupies 2 modular width units.
What conductor sizes can be connected?
The terminals accept solid, stranded and finely stranded conductors with end processing from 1 mm² to 35 mm².
What tightening torque should be used for the terminals?
The screw-type terminals are specified for a tightening torque of 2 N·m.
Can the supply be connected from the top or bottom?
Yes. The power supply cord position is specified as either top or bottom, giving flexibility during panel layout.
What is the operating temperature range?
The device is specified for operation from -25 °C to 40 °C. It may be stored between -40 °C and 70 °C.
What ingress protection rating does it have?
The protection class is IP20 when installed in a distribution board with conductors connected.
What is the mechanical service life?
The typical mechanical service life is 10,000 operating cycles.
What is its approximate weight?
The net weight is approximately 236 g, while the weight with packaging is approximately 262 g.
