Product details

Part identity and key ratings

The Siemens SENTRON 5SY5104-6CC is a 1-pole miniature circuit breaker designed for DC circuits, rated at 4 A with a B tripping characteristic. It interrupts fault currents up to 10 kA at 220 V DC per IEC 60947-2 — that breaking capacity ensures the breaker can clear a bolted DC fault without welding its contacts, which is the critical parameter for DC branch protection in control panels and industrial machinery.

It can be mounted in any position, and the installation depth is 70 mm plus the 76 mm overall depth — this fits standard 80 mm deep enclosures without interference.

For audit purposes, the manufacturer's datasheet and declaration of conformity (IEC 60947-2) are available on request.

Frequently asked questions

Where can I buy 5SY5104-6CC and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ to receive a firm price and lead-time confirmation.

Will 5SY5104-6CC drop into a panel specified around 5SY4116-6CC without rewiring?

Yes — both share the same 18 mm width, 76 mm depth, 90 mm height, quick-assembly DIN-rail mount, and combined top/bottom terminals. The 5SY5104-6CC is a 4 A DC-rated B-curve breaker, while the 5SY4116-6CC is a 16 A AC-rated B-curve breaker; the physical footprint and terminal layout are identical, so no panel rework is needed for the swap.

What compliance documentation is available for 5SY5104-6CC?

The breaker is designed to IEC 60947-2 and carries the SENTRON brand documentation package including a declaration of conformity. It is halogen-free and silicon-free, which supports RoHS and REACH compliance claims.
