The Siemens 5SL6602-8CC is a miniature circuit breaker rated 400 V with a 6 kA breaking capacity, configured as 3+N-pole with a D tripping characteristic and a 2 A current rating. This is a panel-mount device in the SENTRON 5SL series, designed for DIN-rail installation in distribution boards.
Integration Note
The 3+N-pole configuration provides overcurrent protection on all three phases plus a switched neutral — common in three-phase distribution where the neutral must be isolated for maintenance. The D-curve characteristic (10-20x In magnetic trip) suits loads with high starting currents: small motors, transformers, or discharge lighting. At 2 A, this is sized for a low-current subfeed or control transformer primary, not a main feeder.
