PLHT xPole Miniature Circuit Breaker

The PLHT miniature circuit breaker is a protective device equipped with both a thermal and an electromagnetic release that is available in 1-, 2-, 3-, 4- and 3+N pole versions. The PLHT is compatible with AC and DC applications up to 60 V with rated currents from 20 A to 125 A and is available with tripping characteristics B, C and D. It has a switching capacity of up to 25 kA. 

 

The PLHT-V is a special 1-pole version of the PLHT miniature circuit breaker for installation in front of the meter in commercial applications. The PLHT-V is compatible with AC and DC applications up to 60 V with rated currents from 20 A to 63 A and is available with a tripping characteristic that is similar to type D. This special version has a switching capacity of up to 25 kA.

The most commonly used type of overcurrent protection device

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 PLHT miniature circuit breakers are type-tested and approved according to IEC/EN 60947-2 (VDE 0660-101). 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.

The right MCB for every application

Circuit breakers with tripping characteristic B are the standard MCB type used for lighting and socket circuits. For circuits with high peak currents (such as motor circuits) devices with tripping characteristic C are used. Circuit breakers with tripping characteristic D are used for circuits with inductive and capacitive loads, such as solenoid valves, transformers or motors.
