Product details

DC-rated MCB for string and panel protection

The Siemens SENTRON 5SY5201-7CC is a 2-pole miniature circuit breaker rated 1 A at 35 °C with a C tripping characteristic, designed for DC circuits up to 440 V and a breaking capacity of 10 kA per IEC 60947-2.

Panel fit and environmental range

Ambient range spans -40 °C to 75 °C, with derating above 35 °C: 0.93 A at 40 °C, 0.9 A at 45 °C, 0.86 A at 50 °C, 0.82 A at 55 °C. That derating matters if the breaker sits next to heat-generating loads or in a warm enclosure — at 55 °C you lose nearly 20 % of the nominal current.

Frequently asked questions

How do I get current pricing and availability for 5SY5201-7CC?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels.

Will 5SY5201-7CC drop into a panel that was specified around 5SY5240-7 without rewiring?

Yes — both are 2-pole SENTRON MCBs on the same 36 mm (2 MW) footprint, same depth and mounting. The 5SY5240-7 is a 40 A variant; swapping to the 1 A 5SY5201-7CC requires verifying the load current and cable sizing, but the mechanical fit is identical.

What compliance documentation does this brand provide for 5SY5201-7CC (RoHS, REACH, UL, IEC)?

The breaker is designed to IEC 60947-2, carries the CE mark, and is halogen-free and silicon-free. RoHS and REACH declarations are standard with the SENTRON series; contact us for specific certificates.
