Product details

The 5SY4110-7CV is a 1-pole miniature circuit breaker with C-curve trip characteristic, rated 10 A at AC and 250 V single-phase, with a breaking capacity of 15 kA per IEC/EN 60947-2. It occupies one modular width (18 mm) on a DIN rail, mounts in any position, and is IP20 rated with conductors connected.

Thermal derating is baked into the spec: at 40 °C ambient the continuous rating drops to 8.89 A, at 50 °C to 7.6 A, and at 55 °C to 6.91 A.

Panel integration

Sealable — the toggle can be locked in the OFF position for lockout/tagout compliance.

Frequently asked questions

Where can I buy 5SY4110-7CV and how do I get a price?

The part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 5SY4110-7CV drop into a panel specified around 5SY4113-7CV without rewiring?

Yes — both are 1-pole C-curve MCBs in the same 5SY7 family, same 18 mm width, same DIN-rail footprint, same terminal arrangement. The difference is the rated current: 10 A for this part versus 13 A for the peer. If the circuit load is 10 A or less, it is a direct mechanical and electrical swap.

What compliance documentation does this brand provide for 5SY4110-7CV?

The breaker is designed to IEC/EN 60947-2, carries a pollution degree 3 rating, overvoltage category III, and is halogen-free and silicon-free. Specific compliance documentation (RoHS, REACH, UL) should be requested at quote time.
