The Siemens 5SL3301-7MB is a 3-pole miniature circuit breaker (MCB) rated for 400 V AC with a 4.5 kA breaking capacity. At 1 A rated current, this is a low-current branch protector. On a DIN-rail panel, it guards a single control transformer, a PLC power supply feed, or a signal-conditioner loop — not a main feeder.
