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.

Use this dependable motor protection circuit breaker (MPCB) from Eaton to safeguard motors against overload and short circuits. For added convenience, it also functions as a motor on/off switch. A built-in isolator cuts off the current when a fault is detected, keeping you and your workplace safe from electrical hazards. It can accommodate a broad range of currents from 6.3 to 10 A and a high voltage supply of 690 V AC. You'll commonly find this product used for automation, as well as process control applications.

• Three poles for use in three-phase circuits
• Broad operating temperature range of -25°C to +40°C when enclosed, for use in demanding conditions
• Designed for a high number of operations and a long service life
• Ingress protection rating of IP20 for protection against solid objects 12 mm in size and greater

MPCBs are specifically designed to protect motors, while MCCBs are more general circuit-protection devices. While both MPCBs and MCCBs protect against overload and short circuits, MPCBs can also protect motors against phase loss and under-voltage faults.
