It uses a B-curve trip characteristic and is rated at 63 A. This MCB is designed for DIN-rail mounting in distribution boards, lighting panels, and motor control centers where overcurrent protection of branch circuits is required. ## Key Ratings and What They Mean for the Panel The 6 kA breaking capacity at 230/400 V defines the maximum prospective short-circuit current the breaker can safely interrupt. In a site electrical engineer's selectivity study, this figure must exceed the available fault current at the breaker's location — otherwise a higher-rated unit or a current-limiting upstream device is needed.","metaTitle":"Siemens 5SL6163-6CC 1-Pole MCB, B-Curve, 63 A, 6 kA","metaDescription":"Siemens 5SL6163-6CC miniature circuit breaker, 1-pole, B-curve, 63 A, 230/400 V, 6 kA breaking capacity.
