Product details

The 15 kA rating under EN 60898 is the domestic/light-commercial benchmark; the 30 kA under IEC 60947-2 is the industrial installation rating, so this breaker can sit in a panel with high prospective fault current without cascading upstream. The 5 kA UL 1077 rating is typical for supplementary protection in North American panels — not a branch-circuit breaker per UL 489, but accepted for internal equipment protection. The 1-pole design (single modular width unit, 18 mm wide) fits standard DIN-rail enclosures. Mounting position is any; the quick-assembly system snaps onto the rail without tools.

Snap-on DIN rail mount, 1 MW (18 mm) wide. Sealable (tamper-evident cover option available). Ambient temperature range -40 °C to 75 °C; humidity derating applies above 55 °C (max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C).

Frequently asked questions

What is the closest functional second-source to 5SY7110-7?

The 5SY4140-7 is a 1-pole SENTRON MCB with the same C-curve and similar breaking capacities, but it is a 4 A rated device versus the 5SY7110-7's rating. They share the same 18 mm width and DIN-rail footprint, so a panel specified around the 5SY4140-7 will accept the 5SY7110-7 without rewiring — just verify the ampacity match for the circuit.

Where can I buy 5SY7110-7 and how is it quoted?

We supply the 5SY7110-7 against an RFQ. Availability and current pricing are confirmed at quote time. Volume purchases are quoted per lot; compliance documentation (RoHS, REACH, UL, IEC) is included with the shipment.

What are the key dimensions of 5SY7110-7?

Width 18 mm (1 modular unit), height 90 mm, depth 76 mm, installation depth 70 mm. It snaps onto standard DIN rail.

What compliance documentation does Siemens provide for 5SY7110-7?

The part is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077/CSA C22.2 No.235. RoHS and REACH declarations are available with the shipment.
