Circuit breakers

The FAZ6 miniature circuit breaker is a protective device equipped with both a thermal and an electromagnetic release that is available in 1-, 2-, 3-, 4-, 1+N and 3+N pole versions. The FAZ6 is available with rated currents of 0.5 A to 63 A. The switching capacity is 10 kA according to IEC/EN 60947-2 and 6 kA according to IEC/EN 60898-1. A guide for secure terminal connection and a 3-position DIN-rail simplify the installation of the circuit breaker.

Reliable cable protection

MCBs protect cables against damage due to overload and short circuits: In the event of dangerously high currents, the circuit breaker’s bimetallic thermal release will disconnect the power supply. In the event of a short circuit, the electromagnetic release will disconnect the power supply in a timely manner.

A design that is standard-compliant and quality-tested

Circuit breakers that fall within the scope of IEC/EN 60898-1 are primarily intended for use in domestic installations and are designed to be operated by non-experts. IEC/EN 60947-2 applies to circuit breakers in circuits with rated voltages up to 1,000 V AC, or up to 1,500 V DC.

The right MCB for every situation

Circuit breakers with tripping characteristic B are the standard MCB type used for lighting and socket circuits. For circuits with high inrush and peak currents (e.g. motors and luminaire banks) devices with tripping characteristic C are used. Circuit breakers with tripping characteristic D are used for circuits with inductive and capacitive loads (solenoid valves, transformers etc.).
