Product details

It's built for final-subcircuit protection in commercial and industrial panels, switching the neutral conductor as well as the three phases. Dual-rated at 6 kA per IEC/EN 60898-1 and 15 kA per IEC 60947-2 / UL1077, so it covers both domestic-standard and industrial-breaking-capacity specs on the same device.

The 32 A rating holds at 35 °C ambient; at 40 °C it derates to 30.72 A, at 45 °C to 30.08 A, at 50 °C to 29.41 A, and at 55 °C to 28.74 A.

Mounting position is any — vertical, horizontal, upside down — which simplifies panel layout when space is tight. The combined terminal at top and bottom accepts both busbar and cable, and the unit is sealable for tamper-proof installations.

Frequently asked questions

What is the breaking capacity of 5SY6632-6?

It is dual-rated: 6 kA per IEC/EN 60898-1 and 15 kA per IEC 60947-2 / UL1077.

Will 5SY6632-6 drop into a panel designed for 5SY4140-7?

Yes — both are 4-pole SENTRON MCBs on the same DIN-rail footprint (4 modular-width units, 72 mm wide). The 5SY4140-7 is a 40 A C-curve; the 5SY6632-6 is a 32 A B-curve. No rewiring or panel modification needed.

Where can I buy 5SY6632-6?
