The IP20 rating applies with conductors connected — typical for enclosed distribution boards. ## C-curve and 0.5 A rating — what that means on the line C characteristic (5–10× In magnetic trip) suits moderate inrush loads. At 0.5 A, this is a low-current branch breaker. 10 000 mechanical switching cycles typical. Rated voltage is 400 V AC for multi-phase operation, with a maximum of 440 V AC. Single-phase operation is rated at 250 V AC. The DC rating maxes out at 72 V — if you need DC-side protection at higher voltages, this is not the breaker for that rail. Sealable design. Halogen-free and silicon-free.","metaTitle":"Siemens 5SL3205-7MB SENTRON MCB, 2-pole C-curve 0.5 A, 400 V","metaDescription":"Siemens SENTRON 5SL3205-7MB miniature circuit breaker, 2-pole, C characteristic, 0.5 A rated current, 4.5 kA breaking capacity at 400 V AC.
