Product details

The Siemens 5SU1354-4KK10 is a 1P+N residual current operated circuit breaker (RCBO) from the SENTRON Super Resistant K line, combining overcurrent and earth-fault protection in a single 2-module-width (36 mm) package.

Temperature derating — the real current limit

The 10 A rating holds only at 30 °C ambient. At 40 °C it derates to 9.5 A, at 50 °C to 9 A, and at 70 °C to 8 A. The mounting position is unrestricted, but the IP20 rating assumes the distribution board is installed with conductors connected; open-back enclosures void that protection.

At 36 mm wide (2 MW) and 77 mm deep (70 mm installation depth), it occupies standard DIN-rail space — two adjacent 18 mm slots. Supply can enter from top or bottom, which simplifies busbar routing in a crowded enclosure.

Frequently asked questions

Where can I buy 5SU1354-4KK10 and how is it quoted?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, not listed here.

What is the depth and width of 5SU1354-4KK10?

Depth is 77 mm (70 mm installation depth behind the panel face), width is 36 mm (2 modular width units).

Will 5SU1354-4KK10 drop into a panel designed for 5SL6550-7BB?

Physically yes — both are 2 MW wide. But the 5SL6550-7BB is a plain MCB with no residual-current function; swapping in the RCBO adds earth-fault protection but requires the neutral connection that an MCB-only panel may not have wired.

What compliance documentation is available for 5SU1354-4KK10?

The device is rated per EN 60898 (10 kA) and IEC 60947-2 (20 kA), carries overvoltage category III and pollution degree 2, and is halogen-free and silicon-free. Standard Siemens SENTRON declarations of conformity cover RoHS and REACH compliance.
