Product details

Breaking capacity is 15 kA per EN 60898 for standard residential/commercial duty, and 50 kA per IEC 60947-2 for industrial installations where higher fault currents are expected — the 50 kA rating means it can safely interrupt a fault up to that level without cascading upstream, which simplifies coordination in a panel with a transformer-fed bus.

Thermal derating and installation

Rated 1.6 A at 35 °C, derated to 1.36 A at 60 °C — the thermal curve matters if the breaker sits in a warm enclosure or next to other heat-generating devices. Combined top and bottom terminals with touch protection; sealable and halogen-free. Quick-assembly system clips onto the DIN rail without tools.

Frequently asked questions

How do I get current pricing and availability for 5SY7115-7?

Submit an RFQ through this listing; availability and current pricing are confirmed at quote time. The part is sourced through independent distribution channels.

When sourcing 5SY7115-7, what is the closest functional second-source — 5SY4116-7CV?

The 5SY4116-7CV is a direct functional equivalent: same 1-pole, 1.6 A, C-curve, 18 mm width, and 15/50 kA breaking capacities. It drops into the same panel footprint without rewiring.

Will 5SY7115-7 drop into a panel that was specified around 5SY4116-7CV without rewiring?

Yes — both share the same 18 mm width, 1-pole form factor, DIN-rail mounting, and terminal arrangement. No busbar or wiring changes are needed.

What compliance documentation does this brand provide for 5SY7115-7?

The part is certified to EN 60898 and IEC 60947-2. It is halogen-free and silicon-free, and carries a degree of pollution 3 rating. Specific RoHS/REACH/UL declarations should be requested at quote time.
