Product details

Siemens SENTRON 5SY4202-6CC11 — 2A B-Curve MCB, 2-Pole, 10kA

The Siemens SENTRON 5SY4202-6CC11 is a 2-pole miniature circuit breaker rated for 2 A at 400 V AC with a B tripping characteristic, breaking 10 kA per EN 60898. Terminal blocks top and bottom accept solid or stranded copper from 0.75 mm² up to 35 mm², tightened to 2.5–3.5 N·m. Designed for railway applications per its construction, it carries overvoltage category III and energy limiting class 3.

At 72 V DC maximum, it also covers DC control circuits, but the DC breaking capacity is not stated — treat it as a residual rating, not a primary DC breaker. Terminal capacity up to 35 mm² is generous for a 2 A breaker — you can land larger incoming tails without a reducer.

Frequently asked questions

Where can I buy 5SY4202-6CC11 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the listed depth (76 mm) and solid wire range (0.75…35 mm²) on this component line?

The 5SY4202-6CC11 has a depth of 76 mm and accepts solid copper conductors from 0.75 mm² up to 35 mm² at its combination terminals.

Will 5SY4202-6CC11 drop into a panel specified around 5SY6140-6CC without rewiring?

Both are 2-pole SENTRON MCBs on a 36 mm DIN-rail footprint, so the mechanical fit is the same — same width, same rail clip. The difference is electrical: the 5SY4202-6CC11 is a 2 A B-curve, while the 5SY6140-6CC is a different rating/curve. If the panel wiring was sized for the 5SY6140-6CC's terminal range, the 5SY4202-6CC11's 35 mm² maximum is the same, so no rewiring is needed at the terminals. Verify the load current and trip curve against the circuit before swapping.
