Overcurrent circuit breaker series 10kA 1-pole FAZ-Z2/1 278620

Overcurrent circuit breaker FAZ-Z2/1 is a reliable protection for electrical installations, designed for both home and professional applications. 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 effective intervention in the event of serious disturbances.

Characteristics and application

The FAZ-Z2/1 circuit breaker is characterized by a Z tripping characteristic, which means a delayed response to current increase. This makes it particularly well suited for protecting circuits with receivers generating high inrush currents during start-up – such as electric motors or transformers. The rated current of 2A makes it an ideal choice for protecting lighting or socket circuits with lower loads. The ability to connect wires with a cross-section from 1 to 25 mm² (solid and stranded) provides flexibility during installation and allows the circuit breaker to be adapted to different types of wires.

Construction and mounting

The FAZ-Z2/1 circuit breaker is a single-pole device, 1 module wide, which makes it easy to install in electrical distribution boards. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of moisture – therefore, the device should be mounted in dry and well-ventilated places. The ambient temperature range from -25°C to 75°C allows it to be used in a wide range of environmental conditions. Additional possibility of busbar connection from above and below and power connection from above and below increases comfort during installation.

Standards and parameters

The circuit breaker meets the requirements of IEC 60947-2 and IEC 60898-1 standards, confirming its safety and reliability. The rated insulation voltage Ui is 440 V, and the rated impulse withstand voltage Uimp is 4 kV. The device is designed to operate with AC voltage at a frequency of 50-60 Hz and has energy limitation class 3 and surge category III. Power losses are only 3.7 W, which translates to efficient use of electrical energy.
