• Rotating handle with clear switch position (ON and OFF)
• DIN-rail mounting
• Forms part of the xStart family of control gear products
• Rated operating voltage 690Vac
• Typical motor protection accessories – Shunt release 492-1709 & 492-1715, lockable rotary handle 244-0113

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.
