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.

Looking for a reliable way to protect your equipment? Choose this motor protection circuit breaker (MPCB) from Eaton. It functions both as an on/off switch and an isolator with built-in protection against short circuits and overloads. It has a breaking capacity of 60 kA, so it will cut the power to your circuits even in the event of a high surge of current. This robust safety unit is ideal for a range of applications, including automation and process control engineering.

• Isolator switch for safe and easy maintenance
• Three poles for enhanced protection
• Wide operating temperature range of -25° to +55°C for use in demanding environments
• Screw terminals for ease of installation
• Compact dimensions of 93 (length) x 45 (width) x 76 mm (depth) for use in areas where space is limited

An isolator switch lets you disconnect your device from the current so that you can carry out routine maintenance and inspection without the risk of electric shock.
