The 3VA1340-6EE32-0AA0-ZD00: The 70 kA breaking capacity at 415 V puts this in the high-fault category for IEC panels — suitable for installation close to a transformer or in a main distribution board where available fault current exceeds 50 kA. The TM220 thermal-magnetic trip is a fixed-time curve, not electronic; if the application needs adjustable short-time delay for selectivity with downstream feeders, you would step up to a 3VA2 with an ETU electronic trip.
Mounts on a DIN rail or panel-mount via the 3VA1 frame's integrated latching mechanism. The nut keeper kit is a factory-fitted accessory that retains the terminal nuts during high-vibration shipping or operation — common on OEM builds destined for DC power cabinets. Three-pole form factor occupies the standard 3-module width on a DIN-rail assembly.
