The Siemens 5SL4602-7 is a SENTRON miniature circuit breaker (MCB) with a 4-pole 3P+N design, C-curve tripping characteristic, rated 2 A at 400 V AC. That 10 kA SCCR means it safely interrupts a bolted fault at the panelboard without cascading upstream, provided the upstream device is sized for selectivity.
The 5SL4602-7 occupies 4 modular width units (72 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position — handy when the enclosure layout is tight.
