Product details

The Siemens 5SU9156-7KK10 is a SENTRON RCD-operated circuit breaker — an RCBO that combines overcurrent protection and residual current detection in a single 2-module-wide (36 mm) package. The instantaneous design (no intentional time delay on the RCD element) means it trips on the first half-cycle of a residual fault — no selectivity with downstream delayed RCDs, but full speed for personnel protection.

Current derating and mounting

Rated 10 A at 30 °C ambient; derate to 9.4 A at 40 °C, 9.1 A at 45 °C, 8.7 A at 50 °C, and 8.1 A at 55 °C.

Frequently asked questions

What is the depth of 5SU9156-7KK10?

The depth is 77 mm, with an installation depth of 70 mm. The width is 36 mm (2 modular width units), height 90 mm.

Will 5SU9156-7KK10 drop into a panel specified for 5SY7210-7CC?

Both are 2-module-wide (36 mm) SENTRON RCBOs, so the physical footprint and DIN-rail clip are identical. However, the 5SU9156-7KK10 is a 10 A, 10 mA Type A instantaneous device, while the 5SY7210-7CC has different ratings — confirm the trip curve, residual type, and breaking capacity match your panel design before swapping.

Where can I buy 5SU9156-7KK10?
