Circuit breakers

The FAZ 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 FAZ is available with rated currents of 0.16 A to 63 A. Depending on the device type, the switching capacity is 15 kA or 10 kA according to IEC/EN 60947-2, 10 kA according to IEC 60898-1, and 10 kA or 5 kA according to UL 1077.

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

Eaton’s FAZ miniature circuit breakers are type-tested and approved according to IEC/EN 60947-2 (VDE 0660-101). This standard applies to circuit breakers in circuits with rated voltages up to 1,000 V AC, or up to 1,500 V DC. In addition, these protective devices comply with the requirements of the American UL 1077 standard for additional protective elements.

The right type of MCB for every application

For circuits with high inrush and peak currents (e.g. motors and luminaire groups) devices with tripping characteristic C are used. Circuit breakers with tripping characteristic D are used for circuits with inductive and capacitive loads. Tripping characteristic K is intended for circuits with high (inrush) current peaks. Tripping characteristic S is especially suitable for control transformer circuits. Tripping characteristic Z is used for the protection of semiconductors and measuring circuits, especially in the event of high line impedance.

Maximum safety in railway applications

The xEffect range of protective switchgear also ensures the highest safety standards in railway applications. Thanks to compliance with specific standards such as IEC 61373 (Rolling stock equipment – Shock and vibration) and EN 45545-2 (fire protection of railway vehicles), the devices provide maximum safety and performance in rolling stock applications. In addition to standard switchgear, we also offer a wide range of MCBs and RCDs for the connection of ring cable lugs in railway applications.
