MCB 3A, 1P, 220V DC – 5SL5103-7RC

Product Description

Siemens SENTRON MCB – 3A, 1P, 220V DC – 5SL5103-7RC

The Siemens 5SL5103-7RC is a SENTRON 5SL series miniature circuit breaker (MCB) designed for protection of low-voltage AC/DC control and distribution circuits against overload and short-circuit faults. It is commonly used in industrial control panels, automation systems, and DC auxiliary networks where reliable low-current protection is required.

This model is a 1-pole (1P) MCB with C-curve tripping characteristic, suitable for both 220V DC and 230/400V AC systems, making it ideal for control circuits, PLC power supplies, instrumentation, and DC feeders.

With a 10kA breaking capacity, it ensures safe interruption of fault currents and reliable protection of sensitive electrical and electronic equipment in compact installations.
