Product details

It carries a 15 kA breaking capacity per EN 60898 and 40 kA per IEC 60947-2, with a separate 5 kA rating under UL 1077 and CSA C22.2 No.235.

The 40 kA rating under IEC 60947-2 gives this breaker headroom for high-fault installations — think industrial distribution boards with large upstream transformers. The 15 kA per EN 60898 covers the residential and light commercial side. Both ratings are verified; the 5 kA UL 1077 figure confirms it passes North American branch-circuit protection tests. The part also complies with IEC/EN 60898-1 and IEC/EN 60947-2, and carries a pollution degree 3 rating (conductive pollution, typical in factory environments).

Mounting position is any orientation. The neutral conductor is switched (3P+N), so it breaks all poles including neutral. IP20 with connected conductors; sealable for tamper-proofing. Halogen-free and silicon-free construction.

Environmental range

Operates from -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH to 70 °C, 35% RH to 75 °C. Overvoltage category III (fixed installation). Frequency 50/60 Hz.

Current production — no end-of-life notice.

Frequently asked questions

Will 5SY7604-7 drop into a panel specified around 5SY4140-7 without rewiring?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, but verify the tripping characteristic and breaking capacity against your BOM — the 5SY4140-7 carries a different curve and rating. Mechanical fit is the same; electrical substitution depends on the circuit requirements.

What compliance documentation does Siemens provide for 5SY7604-7?

The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No.235. Halogen-free and silicon-free. Standard RoHS/REACH declarations are available from the manufacturer.
