The 40 A rated current (In) and thermal-magnetic TM240 trip unit with adjustable overload protection (Ir = 28...40 A) and short-circuit pickup (Ii = 5...10 x In) let you dial in the protection curve to match a specific load, not just a generic breaker rating. ## Deployment context This is a panel-mount MCCB for IEC distribution boards and motor control centers. The 3-pole construction suits three-phase loads: pumps, conveyors, compressors, or feeder circuits up to 40 A.","metaTitle":"Siemens 3VA1140-5EF32-0AB0 Circuit Breaker, 40A, 55kA @ 415V","metaDescription":"Siemens 3VA1140-5EF32-0AB0 IEC 3VA1 frame 160 MCCB, 40A, 55kA breaking capacity at 415V AC.
