The Siemens 5SY5132-7CC12 is a 1-pole miniature circuit breaker from the 5SY5 series, rated C32 with a 10 kA breaking capacity at 220 V DC. The C-trip curve means it handles moderate inrush currents typical of motor and lighting circuits without nuisance tripping, while still protecting against short circuits and overloads. The 10 kA SCCR at 220 V DC tells you it can safely interrupt a fault up to that level without upstream damage — critical for DC bus protection in control panels or solar combiner boxes.
Panel Integration
Snap-on DIN rail mounting for standard 35 mm rail. The 1-pole form factor takes one module width (roughly 18 mm), so it fits neatly into a populated distribution board without crowding adjacent breakers. Spring-cage terminals accept 0.2–2.5 mm² conductors — strip length 8 mm, torque to the value printed on the housing.
