The Siemens 3VA1132-5EF36-0AG0 is a 3-pole IEC molded case circuit breaker in the 3VA1 series, frame size 160. It carries a 55 kA breaking capacity at 415 V (class M), meaning it can safely interrupt fault currents up to that level on a 400 V distribution bus without needing an upstream current-limiting fuse. The TM240 thermal-magnetic trip unit gives you an adjustable overload (Ir) from 22 A to 32 A and a fixed magnetic short-circuit pickup (Ii) at 5 to 10 times In — so for a 32 A breaker, that's 160 to 320 A instantaneous. That range suits motor branch circuits or feeder protection where you need to ride through inrush without nuisance tripping.
Mounting and integration
Clamp connection terminals accept copper or aluminum conductors up to the frame's rated cross-section. The 3VA1 frame mounts on a DIN rail or panel-mount plate; the compact 3-pole footprint leaves room in a distribution board for additional feeders or metering modules. The factory-fitted auxiliary switch (HP) and trip alarm switch (HP) give you remote status feedback — the auxiliary tracks the breaker's on/off position, the alarm signals a trip event. Both are wired to a terminal block on the breaker face, so you don't need to open the cover to check state.
