The Siemens 3VA1110-4ED32-0AF0 is a 3-pole IEC frame 160 molded-case circuit breaker from the 3VA1 series, rated for line protection with a fixed thermal-magnetic trip unit (TM210). It is set at 100 A overload protection (Ir = 100 A fixed) and a short-circuit pickup of 10 x In (Ii = 1000 A). The breaking capacity class S delivers 36 kA at 415 V AC — enough for most industrial distribution panels where fault currents stay under that threshold.
This breaker mounts on a DIN rail or can be screw-fixed into a panel enclosure. It ships with a nut keeper kit for secure busbar connection. The integrated 1 auxiliary switch HQ and 1 trip alarm switch HQ provide status feedback to a PLC or annunciator panel — useful for remote fault indication without adding external contact blocks.
