The IP20 protection class means it is touch-safe but not sealed against moisture — suitable for indoor panel mounting where no washdown or condensation is expected. ## Integration notes Rated for overvoltage category 3 and energy limiting class 3, this breaker is designed for fixed installation in distribution boards where it provides both overload and short-circuit protection. The neutral conductor switching function (2-pole switching) ensures both phase and neutral are disconnected, which is required for some local wiring codes and for isolating circuits where the neutral is not solidly bonded.","metaTitle":"Siemens 5SQ2270-0KA50 SENTRON MCB, 2-pole C-curve 50 A, 3 kA","metaDescription":"Siemens SENTRON 5SQ2270-0KA50 miniature circuit breaker, 2-pole, C-curve, 50 A rated current, 3 kA breaking capacity per EN 60898, 400 V AC.
