It's configured for line protection with a TM240 thermal-magnetic trip unit, ATAM, rated In=50 A, with overload protection adjustable Ir=35 A...50 A and short-circuit protection Ii=5...10 x In. The 55 kA Icu at 415 V puts this breaker in the M class of breaking capacity for the 3VA1 frame, suitable for downstream distribution where fault currents can reach that level. The 4-pole design with an unprotected neutral suits IT or corner-grounded delta systems common in industrial OEM panels. The nut keeper kit is a mechanical detail for secure busbar mounting — verify the DC Power OEM's specific gland plate and DIN-rail fill factor if integrating into a pre-punched enclosure. For a BOM freeze, note the adjustable overload (Ir=35...50 A) and short-circuit (Ii=5...10 x In) ranges give selectivity flexibility downstream of a larger feeder. The TM240 trip unit is thermal-magnetic with a fixed magnetic pickup — coordination studies should confirm the Ii setting doesn't trip on motor inrush.","metaTitle":"3VA1150-5EF42-0AA0-ZD00 3VA1 IEC Frame 160 55kA @ 415V 4-Pol","metaDescription":"Siemens 3VA1150-5EF42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, breaking capacity class M, Icu=55kA @ 415V, 4-pole, In=50A.
