Overcurrent circuit breaker series 15kA 3+N-pole FAZ-C20/3N 278976

Safety and reliability in your electrical installation

This four-pole circuit breaker of the FAZ-C20/3N series is a key element in protecting electrical circuits. Designed to operate in AC systems with a voltage of 400V, it provides effective protection against overloads and short circuits. The rated short-circuit breaking capacity of 15kA (at 400V) guarantees safety even in the event of large voltage surges. Characteristic C makes it ideal for circuits with devices generating inrush currents, such as motors or transformers – it allows for short-term exceeding of the rated current without unnecessary tripping.

This circuit breaker, thanks to the simultaneous disconnection of the N pole, ensures full protection of the entire circuit. Its compact design (width of 4 modules) facilitates installation in electrical distribution boards, and the IP20 degree of protection protects against accidental contact. Adapted to work in a wide temperature range (-25°C to +75°C) it will perform well in various environmental conditions.

Installation and application – for professionals and demanding users

The FAZ-C20/3N circuit breaker is designed for mounting on TS 35 rail. It accepts solid and stranded wires with a cross-section from 1 mm² to 25 mm², which provides great flexibility during installation. The rated current of 20A makes it ideal for protecting lighting circuits, socket outlets and electrical devices with medium power consumption. Thanks to energy limitation class 3 and surge category III, the circuit breaker meets high standards of safety and reliability.

An additional advantage is the possibility of additional equipment, which allows you to adapt the circuit breaker to specific installation needs. The rated impulse withstand voltage of 4kV provides resistance to sudden voltage spikes. Power losses of 10.5W minimize the impact on the energy efficiency of the system.
