Product details

It is not sized for motor-starting inrush; that calls for a C or D curve. At 400 V AC (phase-to-phase) the 20 kA figure gives headroom for high-fault industrial supplies; the 5 kA UL 1077 / CSA 22.2 No. 235 rating covers North American acceptance on branch circuits.

Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA 22.2 No. 235, so it carries the documentation a maintenance technician needs for panel acceptance: the dual standard listing covers both European and North American compliance scopes in a single part number.

Snap-on DIN-rail mount, any position. The quick-assembly system and combined top/bottom terminals speed wiring in multi-pole panels. Sealable with a lead seal for metering or safety isolation circuits. Ambient range -40 °C to 75 °C covers most indoor and sheltered outdoor enclosures; humidity derating applies above 55 °C (max 95% RH to 55 °C, dropping to 35% at 75 °C).

Frequently asked questions

What is the breaking capacity of 5SY4632-6?

10 kA per IEC 60898-1, 20 kA per IEC 60947-2 at 400 V AC, and 5 kA per UL 1077 / CSA 22.2 No. 235.

Will 5SY4632-6 drop into a panel specified for 5SY4140-7?

Both are 4-module-width SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. The difference is in the tripping curve and rating — verify the B-curve and current rating match your branch circuit before substituting.

What compliance documentation does Siemens provide for 5SY4632-6?

The part carries IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA 22.2 No. 235 certifications. It is halogen-free and silicon-free.
