FAQ
-
What's the difference between an MCB and an MCCB?
An MCB (miniature circuit breaker) is typically rated up to 100A with a fixed, non-adjustable trip and lower breaking capacity, used for final circuits. An MCCB (moulded case circuit breaker) is built for higher currents and fault levels, and is used for main incomers, sub-mains, and feeder protection where an MCB's rating or breaking capacity would be insufficient.
-
When do I need an MCCB instead of an MCB?
Use an MCCB where the prospective fault current or load current exceeds what an MCB is rated to handle safely — typically at the main incomer or major sub-main level of a commercial or industrial distribution board.
-
Does this MCCB have an adjustable trip setting?
Check the specific trip unit type in the Technical Specifications table above — thermal-magnetic MCCBs may have a fixed or adjustable trip range depending on the model; an electronic trip unit typically offers configurable protection curves.
-
Can I install this myself?
No. MCCBs are installed in distribution boards and panels by a licensed electrician, in line with UAE wiring regulations.
