Eaton 40 → 50 A Motor Protection Circuit Breaker, 690 V ac

Eaton Motor Protection Circuit Breaker - PKZM4 Series

Eaton's reliable and robust motor protection circuit breakers are the perfect solution for your motor protection needs, providing protection from electrical faults such as an overload of high voltages, short circuits or relay shutdowns. Two motor protection circuit breakers cover the entire PKZ series ranging from 0.1 A to 63 A, storage and space are reduced for simplified engineering with 18 different types.

Eaton's PKZM4 motor protection range of circuit breakers has been created and designed to act as an intermediary between your devices, protecting vital equipment in the event of unforeseen incidents. This reduces the amount of downtime of machinery to enable operations to continue running smoothly.

The PKZM4 series are manually actuated circuit breakers featuring a breaking capacity of up to 50kA that make current limiters become almost unnecessary. This motor protection range of circuit breakers has a short circuit breaking capacity rated to 150 kA up to 12 A and 50kA up to 32 A. Accessories including auxiliary contacts, trip indicating auxiliary contacts, voltage release and shunt trips can be installed without tools and greatly reduce installation time.

The PKZM4 motor protection circuit breakers have been specifically designed for electrical and mechanical compatibility to the DIL contactor series, making them ideal for the configuration of motor starter combinations.
