It carries a TM240 thermal-magnetic trip unit with ATAM (adjustable thermal, adjustable magnetic) — overload protection Ir adjustable from 88A to 125A, short-circuit protection Ii adjustable 5...10 x In. N-conductor protection is set at 100%. Includes a nut keeper kit for DC Power OEM applications, specified for builds in China. The class M designation sits between standard (S) and very high (H) in the 3VA line, giving you selectivity headroom for downstream distribution panels without overspending on the H frame. ## Panel Integration & Wiring DIN-rail or screw-mount compatible within the 3VA1 frame footprint. The nut keeper kit (included) secures the DC Power OEM variant to the mounting plate — verify the gland plate clearance for the 4-pole width before laying out the enclosure. Spring-cage or box-lug terminals accept copper conductors sized for 125A continuous; torque per the terminal marking on the breaker face.","metaTitle":"Siemens 3VA1112-5GF42-0AA0-ZD00 3VA1 IEC Frame 160, 55kA @ 4","metaDescription":"Siemens 3VA1112-5GF42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, breaking capacity class M Icu=55kA @ 415V, 4-pole, In=125A, TM240 ATAM.
