How do I select the right Motor Protection Circuit Breaker?
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.
To select the right MPCB, consider the systems you and your business rely upon. Checking the features and benefits of each MPCB will prove invaluable when deciding what critical infrastructure you wish to protect.

Eaton Motor Protection Circuit Breaker, 690V, 6.3A - PKZM 0 Series - PKZM0-6.3
Need a reliable solution to protect your motors from electrical faults? This robust motor-protection circuit breaker (MPCB) from Eaton will terminate power supplies in the event of voltage overloads, short circuits or relay shutdowns. As an intermediary between electrical circuits and applications, it prevents damage to devices and equipment. It's suitable for motors in fans, pumps and compressors. Use this unit to reduce the downtime of instruments and prevent interruptions to workflows. By reducing the chance of electrical fire, it also contributes to workplace safety.
Features & Benefits
• Short circuit breaking capacity ensures the unit trips the power before damage is caused to equipment
• Accessories like auxiliary contacts and shunt trips can be fitted without using additional tools
• IP20 (ingress protection) rating indicates this MPCB is touch-proof and protected from items over 12mm
• Accessories like auxiliary contacts and shunt trips can be fitted without using additional tools
• IP20 (ingress protection) rating indicates this MPCB is touch-proof and protected from items over 12mm
How do MPCBs work?
Excess current causes a bimetallic strip in the MPCB to trip. This releases a switch, which moves the electrical contact points apart to confine the arc. The arc is divided and cooled by an insulated metal strip. The contacts close again once the fault has been fixed.
