FAQ
-
What's the difference between an MCCB and an MCB?
MCCBs (moulded case circuit breakers) handle higher current ratings than standard MCBs and are typically used as main incomers or sub-main protection in distribution boards, rather than on individual final circuits.
-
How many poles do I need?
This is a 3-pole, 63A unit, sized for a three-phase supply or sub-main.
-
Can I install this myself?
No — an MCCB of this rating is installed as part of a distribution board's main protection and must be fitted and commissioned by a licensed electrician.
-
Where is this typically used?
As the main incomer or sub-main breaker in commercial, industrial, or larger residential distribution boards, protecting the downstream final-circuit MCBs and RCCBs.
