Overcurrent circuit breaker series 15kA 1-pole FAZ-C25/1 278563

Safety and reliability in your electrical installation

This single-pole circuit breaker from the FAZ series is a key element ensuring protection of electrical circuits against overloads and short circuits. Rated current of 25A combined with a breaking capacity of up to 15kA (at 400V) guarantees effective protection of installations in residential and commercial buildings. Characteristic C ensures that the breaker reacts quickly to high short-circuit currents, but at the same time allows for short-term overloads, which is particularly important when connecting devices with motors or other loads with high starting current.

Design and installation

The FAZ-C25/1 circuit breaker has been designed with easy mounting on a TH35 rail in mind. Compact dimensions – 1 module width – allow for optimal use of space in the switchgear cabinet. The cross-section of the connected wire from 1 to 25 mm² provides flexibility when choosing wires tailored to the specific needs of the installation. The degree of protection IP20 protects against accidental contact and the ingress of solid objects larger than 12.5 mm.

Application and benefits

This circuit breaker is an ideal solution for installers and users looking for reliable circuit protection. The breaking capacity at the level of 15kA according to IEC/EN 60947-2 and energy limitation class 3 testify to the high quality and safety of the device. Additionally, the possibility of mounting additional accessories allows for expanding the functionality of the circuit breaker, e.g. with a contact position indicator. Suitable for operation in a temperature range from -25°C to 75°C, it will perform well even in difficult environmental conditions. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is as high as 4kV – which confirms its high resistance to overvoltage.
