The 3VA1132-3EF32-0AE0 is a Siemens 3VA1 IEC frame 160 molded case circuit breaker with a 32 A thermal-magnetic trip unit (TM240, ATAM). For a 415 V three-phase supply, that puts it in breaking capacity class N, suitable for downstream distribution panels where fault levels are moderate. The overload protection is adjustable from 22 A to 32 A (Ir), and the instantaneous short-circuit pickup (Ii) is set at 5 to 10 times the rated current In — so at the 32 A setting, the magnetic trip fires between 160 A and 320 A.
Deployment context
This breaker mounts in a standard IEC distribution panel or motor control center. The 3-pole construction handles three-phase loads — typical for feeding a sub-distribution board, a group of motor starters, or a large single load like a compressor or chiller. The nut keeper kit and four auxiliary switches (HQ) are factory-fitted, so you get remote status indication (open/closed/tripped) without adding separate accessory modules. The auxiliary switches share the same mounting footprint as the breaker; no extra DIN-rail space is consumed beyond the breaker itself.
