About this part
A moulded case breaker trips on sustained overload and instantly on a short circuit, protecting cables and equipment. On a generator it is the main protection between the alternator and the load.
When to replace it
- Installing a generator output breaker
- Upgrading a distribution board
- A breaker that trips without cause or will not reset
Before you order
Adjustable breakers let the electrician set the trip current to suit the circuit within the breaker's range.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
Questions
What is the difference between an MCB and an MCCB?
MCBs are small DIN-rail breakers for final circuits up to about 63 A. MCCBs are larger, handle higher currents and fault levels, and often have adjustable trip settings.
