It's fitted with a TM220 thermal-magnetic trip unit — the ATFM designation — giving adjustable overload protection from 28 A to 40 A (Ir) and a fixed short-circuit pickup of 10 x In (Ii = 400 A). The nut keeper kit on this variant is specified for a DC Power OEM build in China, so if you're stocking a replacement for that exact line, the hardware matches the panel's captive fasteners. For a 40 A feeder on a 415 V three-phase supply, that's ample margin for most industrial panelboards. The adjustable overload (Ir = 28–40 A) lets you fine-tune the thermal pickup to the actual load cable without swapping the trip unit. The fixed magnetic trip at 10 x In (400 A) is a standard motor-starting characteristic — it rides through inrush without nuisance tripping on most pump and fan loads. ## Panel Integration The 3VA1 frame is a compact 3-pole footprint — three modules wide — so it fits a 9-module or larger distribution board without crowding the gland plate. The nut keeper kit means the panel builder doesn't need a second set of hands to hold the busbar fasteners during assembly; that's a time-saver on repetitive builds.","metaTitle":"Siemens 3VA1140-4EE32-0AA0-ZD00 Circuit Breaker, 40A, 36kA @","metaDescription":"Siemens 3VA1140-4EE32-0AA0-ZD00 circuit breaker, IEC frame 160, 3-pole, 40A, 36kA breaking capacity @ 415V.
