Overcurrent circuit breaker series 10kA 1-pole FAZ-Z4/1 278622

Overcurrent circuit breaker FAZ-Z4/1 is a reliable protection for electrical installations, designed for both home and commercial use. The device effectively protects circuits against overload and short circuit, ensuring safe operation and minimizing the risk of failure. The rated switching capacity of 10 kA (according to IEC 60947-2) guarantees an effective response in the event of serious disturbances.

Characteristics and application

The FAZ-Z4/1 circuit breaker is characterized by a Z tripping characteristic, which means a delayed response to current increase. This makes it particularly recommended for protecting circuits with receivers generating high inrush currents during start-up – such as electric motors or transformers. The rated current of 4A makes it an ideal choice for circuits with lower power consumption, such as lighting or electrical outlets. The ability to connect wires with a cross-section from 1 to 25 mm² provides flexibility during installation and allows you to adapt the circuit breaker to different types of wires.

Construction and mounting

The FAZ-Z4/1 circuit breaker has been designed with easy mounting in electrical distribution boards in mind. Its compact dimensions (1 module width) save space in the distribution cabinet. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of water or dust – therefore, the circuit breaker should be mounted in dry and closed rooms. The ambient temperature range from -25°C to 75°C enables the device to operate in difficult environmental conditions. Made of high-quality materials, it guarantees long-term and trouble-free operation. The rated insulation voltage Ui of 440V ensures safe use in various electrical installations.
