Eaton 0.25 → 0.4 A Motor Protection Circuit Breaker, 690 V ac

Eaton's reliable and robust transformer protective 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-*-T transformer 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 and the PKZM0-*-T transformer protective circuit breakers are matched to the DIL contactor series making the ideal configuration or motor starter combinations. This transformer and 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.

MPCBs are more critical now than ever. Most infrastructures now rely on a motor behind the scenes to power critical uninterruptible systems such as heating, ventilation and cooling. These systems are vital in ensuring business continues as usual, therefore must be protected against overcurrent's, thermal overloads and similar problems.
To select the right MPCB, consider the systems you and your business rely upon. Checking the features and benefits of each MPCB will prove invaluable when deciding what critical infrastructure you wish to protect.

PKZMO accessories can be used allowing additional functions.
