Eaton 0.4 → 0.63 A Motor Protection Circuit Breaker, 690 V ac

Eaton's reliable and robust PKZ motor protection circuit breakers have been produced by Eaton since 1932. They have continued to develop safe and innovative systems that assume the role of international trendsetting for motor protection!

The PKZMO circuit breakers are the perfect solution for optimum safety and protection of motors from faults such as an overload of high voltages, electrical short circuits or relay shutdowns. Down-time of machinery can be detrimental to a business and its operations, Eaton's PKZM0 range of motor protection circuit breakers has been created and designed to act as an intermediary between your devices, offering control and protection for vital equipment in the event of unforeseen incidents. This reduces the amount of downtime of machinery to enable operations to continue running smoothly.

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 circuit breaker 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.
