The Siemens 5SU1324-2RC32 is a SENTRON RCBO combining overcurrent and residual current protection in a single 4-module-wide unit. Rated 32 A with a D tripping characteristic and 30 mA Type AC residual sensitivity, it protects circuits against both overload/short-circuit and earth leakage. Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher IEC figure matters when the device is used as a main or branch breaker in an industrial panel where fault currents can exceed the residential standard. The D characteristic means it tolerates the high inrush of motor or transformer loads without nuisance tripping.
Panel fit and deployment
Snap-on DIN-rail mount, 4-module width (72 mm), 70 mm installation depth. IP20 with connected conductors — standard for enclosed distribution boards. Supply can enter from top or bottom; mounting position is unrestricted. Rated for overvoltage category III and pollution degree 2, so it is suited for fixed-installation sub-distribution boards in residential or light commercial panels.
