100Amp 3-Pole Moulded Case Circuit Breaker
The 100Amp 3-Pole Moulded Case Circuit Breaker protects a circuit against overload and short circuit, rated 100 A with 3 poles.
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.
If the old part has no readable number, send us a clear photo with the engine or alternator nameplate and we will identify it before you buy.
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.
