Product details

C-curve 1 A MCB for 400 V AC railway and industrial panels

At 1 A, this is a control-circuit or instrumentation feeder breaker, not a main distribution device.

DIN-rail footprint and terminal handling

Accepts solid or stranded copper from 0.75 mm² up to 35 mm² at the screw-type terminals, tightened to 2.5–3.5 N·m — enough for a single 6 mm² feed or a loop-through of two 4 mm² conductors. IP20 with connected conductors — protected against finger contact once wired, but not against dripping water. This is a dry indoor panel breaker, not a washdown enclosure device. The sealable option (padlockable toggle) allows lockout/tagout on the breaker handle without an external lockout hasp.

Frequently asked questions

Where can I buy 5SY4201-7CC11 and how do I get a price?

The part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — no stock count or price is published here.

What is the depth of 5SY4201-7CC11?

The depth is 76 mm (including the terminal structure), with an installation depth of 70 mm into the enclosure.

What solid conductor cross-section does 5SY4201-7CC11 accept?

The terminals accept solid copper from 0.75 mm² up to 35 mm², and stranded from 0.75 mm² up to 35 mm².

Will 5SY4201-7CC11 drop into a panel specified around 5SY7140-8CC without rewiring?

Both are 2-pole, 36 mm wide SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. However, the 5SY4201-7CC11 is rated 1 A while the 5SY7140-8CC has a different rating — verify the circuit's load current and cable sizing before swapping; the terminals accept the same conductor range.

What compliance documentation does Siemens provide for 5SY4201-7CC11?

The part carries the EN 60898 rating (10 kA breaking capacity) and is designed for railway applications (EN 50155 environment). It is halogen-free and silicon-free. For specific RoHS, REACH, and UL documentation, request the manufacturer's declaration of conformity with your RFQ — the evidence does not list a specific UL file number or RoHS certificate.
