Eaton 4 A Motor Protection Circuit Breaker, 690 V

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.

• Manually-actuated motor protective circuit breaker
• Rotating handle with clear switch position (ON and OFF)
• DIN-rail mounting
• Forms part of the xStart family of control gear products
• Rated operating voltage 690Vac
• Typical motor protection accessories – Shunt release 492-1709 & 492-1715, lockable rotary handle 244-0113

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.

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
• Compact dimensions of 93 (length) x 45 (width) x 76 mm (depth) for use in tight spaces
• Ingress protection rating of IP20 for protection against small objects of 12 mm in size and larger

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.
