Product details

Breaking capacity — two ratings, one decision

For DC circuits, it's rated 15 kA at 60 V (max 72 V) per IEC 60947-2, which covers most industrial DC control buses and small UPS feeds.

Mounts in any position via the quick-assembly system (snap-on DIN rail). At 72 mm wide (4 modular units), it occupies four standard 18 mm slots. Ambient range runs -40 °C to 75 °C, with humidity derating above 55 °C (95% RH up to 55 °C, then 55% up to 70 °C, 35% up to 75 °C).

Designed to IEC/EN 60898-1 and IEC/EN 60947-2, with UL 1077 recognition (supplementary protector). Halogen-free and silicon-free construction, which matters for clean-room or semiconductor-adjacent installations where outgassing contaminates optics or wafers. The sealable option (tamper-evident cover) is available for revenue-metering or safety-lockout applications.

Frequently asked questions

What is the breaking capacity of 5SY6632-7?

6 kA per IEC/EN 60898-1 and 15 kA per IEC 60947-2 at 400 V AC. For DC circuits, it's rated 15 kA at 60 V (max 72 V). Under UL 1077, the interrupting rating is 5 kA at 400 V AC.

Will 5SY6632-7 drop into a panel designed for 5SY4140-7?

Mechanically yes — both share the same 72 mm width (4 modular units) and quick-assembly DIN-rail mounting. The 5SY4140-7 is a different pole/curve variant, so check your circuit requirements before substituting, but the panel cutout and rail position are identical.

What compliance documentation does Siemens provide for 5SY6632-7?

The breaker complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077. It's halogen-free and silicon-free. Standard documentation includes the declaration of conformity and UL recognition file; RoHS and REACH declarations are available from Siemens on request.

Where can I buy 5SY6632-7 and how is it quoted?
