IEC 125A MCCB Molded Case Switch 3P Circuit Protector

Product​‍​‌‍​‍‌​‍​‌‍​‍‌ Description

This molded case circuit breaker (MCCB) is a perfect fit for AC 50Hz power distribution networks, rated operating voltages up to 400V and rated currents up to 800A and a max insulation voltage of 800V. It is excellent for electrically distributing energy and at the same time, safeguarding the circuit and the connected equipment against overloads, short circuits, and undervoltage. Moreover, it is capable of handling a limited motor starting and can be used as a trustworthy protection device for electrical systems. Small in size, with high breaking capacity and minimal arcing, the MCCB can be mounted either vertically or horizontally. The product conforms to IEC60947-2, GB14048.2, and other standards.
