Eaton 4A PKZM 0 Motor Protection Circuit Breaker, 690V, 40 °C, 25 °C

When you need robust protection for motors in your industrial automation or process control applications, choose this motor protection circuit breaker (MPCB) from Eaton. It combines a motor on/off switch and isolator with protection from short circuits and overload, making it a convenient choice for safely operating your motor. You can use it for low-current applications of 2.5 to 4 A and high supply voltages of up to 690 V AC. It has three poles for safe use in a three-phase electrical system.

• Designed for a high number of operations for reliability and a long service life

By offering protection to your motor, an MPCB eliminates the need for frequent replacement and repair of motor parts. This reduces downtime for maintenance and keeps your processes running smoothly and efficiently.

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.

• Manually-actuated motor protective circuit breaker

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.
