MCCBs take over where DIN-rail MCBs run out: main switchboards, sub-mains, motor feeds and plant. Ours are 3 pole, 100 A to 250 A, from Hager, Schneider, Legrand and CBI Heinemann, with the breaking capacity (25 kA to 70 kA) shown on each listing.
Check three things before you order: the amp rating against your load and cable, the kA rating against the fault level at the board, and whether it suits your enclosure and any accessories, like an extended rotary handle. If you're matching an existing board, the brand and series matter more than the price.

Frequently asked questions
What is an MCCB breaker used for?
An MCCB protects higher-current circuits than a DIN-rail MCB: main switches, sub-mains, motor circuits and plant feeds. Ours are all 3 pole, 100 A to 250 A. Your electrician should size it to the load, the cable and the fault level at the board.
How much does an MCCB cost?
It depends on the frame size, amp rating, kA rating and brand, and each listing shows its current price. For bulk pricing, email info@alledirect.com with the part numbers or ratings and quantities.
Do you sell adjustable MCCBs?
Some MCCBs have adjustable trip settings and some are fixed. Check the datasheet on each listing, or email info@alledirect.com with the trip range you need and we'll confirm before you buy.
Can I buy MCCB accessories like rotary handles?
Yes. Extended rotary handles and distribution blocks are in our MCCB accessories collection. They're usually brand and frame specific, so match them to your breaker.
