The Siemens SENTRON 5SL6204-8CC is a 2-pole miniature circuit breaker with a D tripping characteristic, rated 4 A at 400 V AC and a 6 kA breaking capacity per EN 60898. Two poles switch both phase conductors, with no neutral pole switching on this variant.
At 36 mm wide (2 width units), 90 mm tall, and 76 mm deep with a 70 mm installation depth, this MCB snaps onto a standard DIN rail in any mounting position. The IP20 rating applies with conductors connected; touch protection is built into the terminals. Sealable design allows the panel builder to lock the toggle position after commissioning.
