Product details

Integrator note: 5SY4201-8CC11

The Siemens SENTRON 5SY4201-8CC11 is a 2-pole miniature circuit breaker with a D tripping curve, rated 1 A at 400 V AC.

Panel fit & wiring

Width is 36 mm (2 width units), depth 76 mm, installation depth 70 mm. Terminals accept solid or stranded conductors from 0.75 to 35 mm² — large enough for the feed-through on a 1 A circuit. Tightening torque 2.5 to 3.5 N·m. Sealable cover is standard, and touch protection is built in.

Ambient & environmental

Rated for ambient temperatures from -40 to +70 °C; storage range is -40 to +75 °C. Halogen-free and silicon-free construction. Overvoltage category III. Rated frequency 50/60 Hz. The multi-phase rating at 440 V AC covers line-to-line faults in three-phase systems.

Frequently asked questions

What is the breaking capacity of 5SY4201-8CC11?

10 kA per EN 60898 at 400 V AC. That is the rated short-circuit capacity the breaker can safely interrupt under standard test conditions.

Where can I buy 5SY4201-8CC11 and what is the lead time?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time; submit an RFQ for a real ETA.

Will 5SY4201-8CC11 drop into a panel specified for 5SY3132-6?

Both are SENTRON 2-pole MCBs on the same DIN-rail footprint. The 5SY3132-6 carries a different tripping curve and current rating, so verify the circuit's protection requirements before substitution. Physically they share the same 36 mm width and mounting system, but the electrical ratings differ.
