It provides line protection via a TM240 thermal-magnetic trip unit with adjustable overload protection Ir=35 A...50 A and short-circuit protection Ii=5...10 x In. The adjustable overload band (Ir = 35...50 A) lets you fine-tune the continuous current protection to match the downstream load, while the short-circuit pickup range (Ii = 5...10 x In) gives flexibility to coordinate with upstream breakers. The TM240 designation indicates a thermal-magnetic trip curve optimized for cable and busbar protection; it is not a motor-protective (mag-only) curve, so it is best applied on feeders or distribution circuits rather than direct motor starting.","metaTitle":"Siemens 3VA1150-4EF32-0DC0 IEC Frame 160 MCCB, 50A, 36kA @ 4","metaDescription":"Siemens 3VA1150-4EF32-0DC0 3-pole MCCB, 50A, Icu=36kA @ 415V, TM240 overload, UVR 208-230V AC, 2 aux switches.
