Motor protection circuit breakers – reliable protection for your devices

The PKZM01-2.5-EA motor protection circuit breaker is a key element in protecting electrical installations, designed to protect electric motors from overload and short circuit. The device combines the functions of an overload and short-circuit breaker, providing comprehensive protection. Its compact design and high reliability make it an ideal solution for both professional installers and end users.

Characteristics and application

The PKZM01-2.5-EA circuit breaker from Eaton's PKZM0 series is a three-pole device with a current setting range of 1.6-2.5A. The rated short-circuit breaking capacity at 400V AC is as high as 50kA, guaranteeing effective protection even in the event of serious disturbances in the network. The thermal-magnetic tripping method ensures a precise response to overloads and short circuits. Thanks to its phase failure sensitivity, the circuit breaker also protects the motor against damage caused by voltage asymmetry. The device is designed for permanent installation and finds application in a wide range of industrial and commercial applications – from simple home installations to advanced control systems.

Advantages and benefits
