Product details

Breaking capacity is dual-rated: 10 kA according to IEC 60898-1 (the household standard) and 20 kA per IEC 60947-2 (the industrial standard), with an additional 15 kA at DC per IEC 60947-2 and 5 kA per UL 1077. That means the same unit covers both a building-services spec and an industrial panel spec without a separate high-break variant.

Mountable in any position, with a quick-assembly fastening system. Sealable cover option is available for applications requiring tamper evidence.

Humidity influence is specified: max 95% RH at 55 °C, derating to 35% RH at 75 °C.

Frequently asked questions

What is the closest functional second-source — 5SL4363-7?

The 5SL4363-7 is a Siemens SENTRON MCB in the same physical footprint (2 MW, 36 mm wide) but typically a B-curve variant. The 5SY4510-7 uses a C-curve, so it will drop into the same panel location without rewiring, but the trip curve differs — check the load's inrush characteristic before substituting.

What compliance documentation does this brand provide?

The 5SY4510-7 is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. It is halogen-free and silicon-free. Standard Siemens declarations for RoHS, REACH, and CE are available with the shipment.
