CNC Electric 2 Pole MCB 10A–63A (YCB7H) – Double Pole AC Circuit Breaker
Out of stock
Double pole 230V/400V AC miniature circuit breaker that switches live and neutral together. 6kA breaking capacity, C-curve, DIN-rail mount, available from 10A to 63A.
The CNC Electric YCB7H 2 pole MCB cuts both live and neutral at the same moment, so the circuit is fully isolated when it trips. That makes it a sensible main incoming breaker for a single-phase distribution board in a home, shop or office.

Frequently Asked Questions
What is the difference between a 1 pole and a 2 pole MCB?
A 1 pole MCB switches only the live wire. A 2 pole MCB switches live and neutral together, giving complete isolation of the circuit.
Which current rating should I choose?
Pick the rating from your load current and cable size. The range runs 10A, 16A, 20A, 25A, 32A, 40A and 63A. If unsure, ask a qualified electrician.
Is this suitable for DC solar circuits?
No. This is an AC breaker. For solar DC strings use a DC-rated breaker from our DC Breaker category.
