Product details

The Siemens 5SU1653-1KK13 is a 1P+N RCBO from the SENTRON series — a combined overcurrent and residual current device that fits a standard 36 mm wide DIN-rail slot (2 modular width units).

Thermal derating and installation

Above that, the continuous current must be derated: 12.48 A at 40 °C, 12.22 A at 45 °C, 11.96 A at 50 °C, 11.57 A at 55 °C, 11.31 A at 60 °C, 10.53 A at 65 °C, and 10.01 A at 70 °C. Installation depth is 70 mm, with an overall depth of 77 mm including the front projection. The IP20 rating applies only when the distribution board is installed with conductors connected — no exposed live parts during normal operation. Degree of pollution 2 and overvoltage category III cover standard indoor panel environments.

Frequently asked questions

Where can I buy 5SU1653-1KK13 and how do I get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

When sourcing 5SU1653-1KK13, what's the closest functional second-source — 5SY7210-7CC?

The 5SY7210-7CC is a different class — it's a miniature circuit breaker (MCB) without residual current protection. The 5SU1653-1KK13 is an RCBO combining overcurrent and RCD in one unit. They are not drop-in substitutes; the 5SU1653-1KK13 replaces both an MCB and a separate RCD in a single 2-module slot.

What is 5SU1653-1KK13's listed depth (77 mm) on this component line?

The overall depth is 77 mm, with an installation depth of 70 mm. The extra 7 mm accounts for the front projection of the toggle and test button.

What is 5SU1653-1KK13's listed width (36 mm) on this component line?

Width is 36 mm, which corresponds to 2 modular width units (MW) on a standard DIN rail. This occupies two adjacent 18 mm slots in a distribution board.
