The Siemens SENTRON 5SL3201-7 is a 2-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 1 A at 30 °C and 400 V AC.
At 30 °C ambient the breaker carries 1 A continuously. At 40 °C it derates to 0.95 A, and at 45 °C to 0.92 A — per the datasheet, so if the panel runs warm (common in a crowded enclosure), factor that into the load calculation. The 1 A rating is the same for AC and DC (72 V DC max), which is useful for DC control circuits fed from a small transformer.
Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
The 5SL4120-7CC is a 2-pole C-curve breaker rated 20 A, not 1 A. The physical footprint (2 MW, 36 mm wide) is the same, so it drops into the same DIN-rail slot, but the current rating is 20× higher — not a functional substitute for a 1 A circuit.
The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code. The product is designed per EN 60898 and IEC 60947-2, which are the relevant standards for miniature circuit breakers.
