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.

This reliable motor protection circuit breaker (MPCB) from Eaton offers protection from overload and short circuits while also acting as a motor on/off switch. It has a built-in isolator switch that lets you disconnect your equipment and perform maintenance safely. This multi-function device can tolerate currents of up to 60 kA, ensuring safety even in the event of a high-current surge. You'll find circuit breakers like this one used in automation applications, as well as process-control applications.

• Three poles for use with three-phase circuits
• Ingress protection rating of IP20 for protection against solid objects measuring 12 mm in size or smaller
• Wide operating temperature range of -25°C to +40°C for use in harsh environments

You should consider the current rating and voltage rating when selecting a MPCB. This Eaton MPCB is suitable for motors with a current rating between 1.6 A and 2.5 A and a supply voltage of 690 V AC, so it's a good choice for low-current, high-voltage applications.
