Frequently Asked Questions:
Q. What is the difference between MCBs and MCCBs?
A.
- MCBs protect items from current overloads while MCCBs protect equipment from fault currents & excess temperature rise.
- The tripping circuit of MCBs is fixed while MCCBs have a movable tripping circuit.
- MCBs have comparatively low interrupting ratings than MCCBs.
Q. What causes moulded case circuit breakers to trip?
A. Overloading of a circuit is the main reason that leads to frequent short-circuit tripping.
Q. What to check before operating Eaton ED3150 circuit breaker?
A.
- Remove dust or moisture from the surface of the circuit breaker with a vacuum or cloth. Do not blow debris into the circuit breaker.
- Switch to ON and OFF multiple times to ensure that the mechanical linkages are free.
- Check base, operating handle and cover for any cracks, discolouration & chipping.
- Check connectors and terminals for signs of overheating and looseness.
- Check the mounting hardware and the area where it is installed.
