ABB 20A 400V four pole AC MCB
Compact Home SH200 miniature circuit breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electro-mechanic tripping mechanism for short circuit protection. They have C curve characteristics, and four pole configuration, breaking capacities up to 10 kA at 230/400 V AC and rated currents up to 20A. This SH200 MCB complies with IEC/EN 60898-1, allowing the use of residential applications.

1. How it will act under overload conditions?
This MCB will protect your appliances automatically by tripping when overload and a short circuit occurs.
2. Is this a certified product?
Yes, ABB MCB has CE, CB certificates.
3. Is there any warranty?
Yes, 1 year.
4. Can we use this AC MCB for residential purposes?
5. Can we use AC MCB in the DC circuit?
Since there is no 0v point, the AC breaker design will NOT work in a DC circuit.
