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 solution to protect your electrical motors and reduce machinery downtime? This motor protection circuit breaker from Eaton prevents electrical faults like voltage overloads, short circuits and relay shutdowns. It acts as an intermediary device to protect crucial and costly equipment and prevent loss of productivity. Screw terminals mean you can make secure connections without needing to use special tools. Install this circuit breaker on motors running assembly and production lines in industrial settings.

• Manually actuated, so it provides fuseless protection against short circuits, overloads and phase failures
• Rotating handle with clearly marked ON and OFF positions prevents operating mistakes
• DIN rail mounting capability lets you organise installations and save space on busy boards

When selecting a motor protection circuit breaker, consider the motor's voltage and current specifications. Your choice of circuit breaker must match these. This device from Eaton is suitable for use with 690V motors, with currents of between 25A to 32A.
