The FAZ-NA / FAZ-RT miniature circuit breaker is a protective device equipped with both a thermal and an electromagnetic release that is available in 1-, 2-, 3- and 4- pole versions. The FAZ-NA is available with rated currents of 0.5 A to 63 A. The switching capacity is 15 kA according to IEC/EN 60947-2, and 10 kA or 14 kA according to UL 489/CSA C22.2 No. 5, depending on the device type.

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

IEC/EN 60947-2 (VDE 0660-101) applies to circuit breakers in circuits with rated voltages up to 1,000 V AC, or up to 1,500 V DC. UL 489 and CSA-C22.2 No. 5 prescribe much larger clearances and creepage distances than the IEC standard. The FAZ-NA MCBs are also suitable for applications that fall within the scope of UL 1077/CSA C22.2 No. 235.

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 inductive and capacitive loads (solenoid valves, transformers etc.).
