The PLZ4 miniature circuit breaker (MCB) is a protective device that’s equipped with both a thermal and an electromagnetic release. The former responds in the event of an overload, while the latter offers protection against short circuits. The 1+N-pole PLZ4 is 2 HP wide and is available with rated currents from 0.16 A to 63 A.

It is not only suitable for conventional AC applications but also for DC applications up to 48 V. It has a switching capacity of 4.5 kA.

The right MCB for every situation

When selecting the right type of circuit breaker for a particular application, the following three criteria must be taken into account:

1) Current limiting class (= selectivity class)
2) Rated current
3) Tripping characteristics

A design that’s standard-compliant and quality-tested

In principle, all Eaton miniature circuit breakers are type-tested and approved in accordance with either IEC/EN 60898-1 or IEC/EN 60947-2. 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 transitional shift is complete

Miniature circuit breakers are now among the most common overcurrent protection devices. Traditional fuses are increasingly being replaced by modern circuit breakers that can be switched on again after tripping.
Eaton offers premium miniature circuit breakers with different rated currents and tripping characteristics, for residential and commercial applications (xPole series) as well as for industrial applications (xEffect series). The basic task of MCBs is to protect the cables in low-voltage networks against damage due to overload and short circuits.
