Product details

The Siemens SENTRON 5SU1354-1RC32 is a 2-pole (1P+N) RCBO combining overcurrent protection and residual current detection in a single 36 mm wide (2-module) DIN-rail unit. The 4 kV surge voltage resistance (rated impulse withstand) and overvoltage category III rating confirm it is designed for fixed-installation distribution boards, not for plug-in portable use.

Depth is 70 mm, height 90 mm — fits standard enclosure cutouts. IP20 protection applies only when installed in a distribution board with conductors connected — treat it as a panel-internal device, not suitable for exposed or washdown locations.

Frequently asked questions

Where can I buy 5SU1354-1RC32 and how is it quoted?

It is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures or prices are published here.

What is the breaking capacity of 5SU1354-1RC32?

10 kA per EN 60898 and 15 kA per IEC 60947-2, so it covers the majority of residential and light commercial panelboard fault levels without needing upstream fusing.

Will 5SU1354-1RC32 drop into a panel specified around 5SL4363-7?

No — the 5SL4363-7 is a 3-pole miniature circuit breaker (MCB) with a 54 mm width, while the 5SU1354-1RC32 is a 2-pole RCBO at 36 mm. They serve different functions (overcurrent-only vs combined RCD+MCB) and have different footprints; rewiring and a different DIN-space allocation would be required.
