SH204-C32 Miniature Circuit Breaker (MCB)
Compact Home SH200 miniature circuit breakers are current limiting. They feature two tripping mechanisms: a delayed thermal tripping mechanism for overload protection and an electromechanic tripping mechanism for short circuit protection. Available in characteristics B and C as well as configurations 1P, 1P+N, 2P, 3P, 3P+N, and 4P. They offer breaking capacity up to 6 kA at 230/400 V AC and rated currents up to 40 A. All MCBs comply with IEC/EN 60898-1, suitable for residential applications.
