Frequently Asked Questions:

Q. How to reset a moulded case circuit breaker that has been tripped?

A. When the breaker trips, it can be reset again by pressing the OFF and then ON pushbutton to close the breaker contacts and start the current flow.

Q. What is interrupt capacity?

A. Interrupt capacity is defined as the maximum current an MCCB can safely interrupt in case of short circuits.

Q. What is the breaking capacity of an MCCB?

A. The breaking capacity of an MCCB is defined as the maximum level of fault current which can be safely cleared by tripping, to prevent permanent damage.
