What it is and what it protects
The Siemens 5SJ6132-7 is a 1-pole SENTRON miniature circuit breaker from the 5SJ6 series, rated 32 A at 240 V AC with a C tripping characteristic and a 6 kA breaking capacity per EN 60898 and IEC 60947-2. That C-curve means it's built for moderate inrush loads — think motor starters, contactor coils, or small transformers — where the magnetic trip holds through a short surge but clears a hard fault fast. On the DC side it's rated to 60 V, so it can also serve a 48 V control bus or a small battery-backed circuit.
Fit and panel integration
It snaps onto standard DIN rail, occupies a single width unit, and installs 70 mm deep. Mounting position is any orientation. The IP20 rating applies with conductors connected. Terminal touch protection is included.
