Product details

The Siemens 5SY4260-7 is a SENTRON 2-pole miniature circuit breaker with a C-curve trip characteristic, rated 10 kA breaking capacity per EN 60898-1 and 15 kA per IEC 60947-2 at 400 V AC. It also carries a 15 kA DC rating at 60 V (72 V max) per IEC 60947-2, and 5 kA per UL 1077.

The 76 mm depth (70 mm installation depth) leaves clearance for standard 80 mm deep enclosures. IP20 with connected conductors; suitable for panel environments, not washdown zones.

Environmental range

Rated for -40 °C to 75 °C ambient, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Mount in any position. Sealable to prevent tamper — useful for metering or critical circuits.

Frequently asked questions

What are the key ratings of 5SY4260-7?

2-pole, C-curve, 10 kA per EN 60898-1, 15 kA per IEC 60947-2 at 400 V AC, 15 kA at 60 V DC. Rated 400 V AC (440 V max multi- or single-phase), 60 V DC (72 V max).

Will 5SY4260-7 drop into a panel specified for 5SY4140-7?

Yes — both are 2-pole SENTRON MCBs with the same 36 mm width (2 MW), same DIN-rail mounting, same depth. The difference is the trip curve: 5SY4140-7 is a B-curve (3–5× In) for resistive/light loads; 5SY4260-7 is a C-curve (5–10× In) for motor or moderate-inrush circuits. No rewiring needed if the panel was laid out for a 2-pole SENTRON.

Where can I buy 5SY4260-7?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
