Product details

DC-rated MCB for 220 V circuits

The Siemens SENTRON 5SL5104-7RC is a 1-pole miniature circuit breaker rated for 4 A at 220 V DC with a C tripping characteristic and 10 kA breaking capacity. This is a DC-specific variant — the operating voltage is DC only, not AC, so it's the right pick for DC distribution panels, telecom power supplies, or solar combiner boxes where you need overcurrent protection on a 220 V DC bus.

Environmental range and pollution rating

The product designation explicitly lists suitability for residential buildings/infrastructure, so it's not intended for heavy industrial motor circuits but fits commercial lighting panels, HVAC disconnects, and building power distribution.

Frequently asked questions

What is the closest functional alternative to 5SL5104-7RC?

The 5SY6006-7 is a 1P+N C-curve 6 A AC MCB with the same 18 mm width and 76 mm depth, but it's rated for AC only (250 V max) and includes a switched neutral. The 5SL5104-7RC is DC-only at 220 V and does not switch the neutral. They share the same SENTRON platform, same housing, and same DIN-rail clip — so a panel designed for the 5SY6006-7 can physically accept the 5SL5104-7RC without rewiring the DIN rail, but the circuit ratings and neutral handling are different. Verify the system voltage and neutral switching requirement before substituting.

Where can I buy 5SL5104-7RC and get current pricing?
