About this part
MCCBs cover the range above miniature breakers, from around 63 A up to 800 A and beyond, and are chosen by current rating, number of poles and breaking capacity.
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
Match the rating to the cable and the load, and choose 3 or 4 poles to suit the installation. Breakers must be installed by a qualified electrician.
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.
