IP20 with connected conductors — protected against finger contact once wired, but not against dripping water. This is a dry indoor panel breaker, not a washdown enclosure device. The sealable option (padlockable toggle) allows lockout/tagout on the breaker handle without an external lockout hasp.","metaTitle":"Siemens 5SY4201-7CC11 SENTRON MCB, 2P C-curve 1A 10kA","metaDescription":"Siemens SENTRON 5SY4201-7CC11 miniature circuit breaker, 2-pole, C-curve, 1 A rated, 10 kA breaking capacity per EN 60898.
