EATON MOTOR PROTECTION CIRCUIT BREAKER – PKZM0 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.
Down-time of machinery can be detrimental to a business and its operations,
Eaton’s PKZM0 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 PKZM0 motor protection circuit breakers are matched to the DIL contactor series making the ideal configuration or motor starter combinations. 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.
