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.

Manage and protect your electrical motor with this motor protection circuit breaker from Eaton. It acts as an intermediary between devices to safeguard against faults like short circuits, high voltage overloads and relay shutdowns. This means less interruption to your processes and reduced downtime. For extra protection, the unit can also detect phase failures. As it's resistant to mechanical shock and suitable for use in hazardous areas where explosive atmospheres may be present, this breaker is a safe choice for demanding environments. You can use it in heating, cooling and ventilation applications in industrial and commercial environments.

• Screw terminals hold wiring securely, so there's little chance of conductors accidentally working loose
• Long mechanical lifespan of up to 6 million operations for consistent reliability throughout its service life
• Turn button actuator that's simple to control manually
• Protected against direct contact when actuated from the front for operator safety

This circuit breaker's test setting lets you check that the device is in good working order in a controlled setting before installing it in a live situation where you depend on it for safety.
