The Siemens 5SL6603-7BB is a miniature circuit breaker (MCB) rated 400 V with a 6 kA breaking capacity, 3+N-pole configuration, C-trip curve, and 3 A rated current. The 3+N-pole arrangement gives overcurrent protection on all three phases plus a switched neutral, so it fits three-phase panelboards where the neutral needs isolation for maintenance or fault clearing.
