Product details

The Siemens SENTRON 5SU1326-6FP25 is a 2-pole RCBO (residual current operated circuit breaker with overcurrent protection) combining a 25 A B-curve MCB and a 30 mA Type A RCD in a single 36 mm wide, 2-module-width housing. It is rated for 230/240 V AC at 50 Hz, with a breaking capacity of 6 kA per EN 60898 and 7.5 kA per IEC 60947-2.

DIN-rail fit and panel integration

It mounts in any position and accepts supply from either top or bottom. The IP20 rating applies only when installed in a distribution board with connected conductors — it is not a standalone outdoor device.

Frequently asked questions

What is the breaking capacity of 5SU1326-6FP25?

6 kA per EN 60898 and 7.5 kA per IEC 60947-2 at 230/240 V AC.

What is the difference between 5SU1326-6FP25 and 5SU9354-7KK16?

The 5SU9354-7KK16 is a 1P+N RCD-operated circuit breaker with a C-curve, 10 kA breaking capacity, and a 1-module protected pole. The 5SU1326-6FP25 is a 2-pole RCBO with a B-curve, 6 kA breaking capacity, and both poles protected. They share the same 36 mm width and DIN-rail footprint, but the 5SU1326-6FP25 provides full overcurrent protection on both poles and a lower inrush tolerance (B-curve), while the 5SU9354-7KK16 offers higher fault-clearing capacity on a single protected pole.

Where can I buy 5SU1326-6FP25?
