The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir = 44…63 A) and fixed short-circuit pickup (Ii = 5…10 × In), so you set the Ir to match the cable or load ampacity, not the breaker frame. ## Protection and accessories This breaker ships with a factory-fitted shunt trip (STL) rated 110–127 V DC / AC 50/60 Hz — a remote-trip coil for emergency-stop or supervisory circuits. The clamp connection terminals accept copper or aluminum conductors without lugs, which saves panel space and installation time compared to bolted connections.","metaTitle":"Siemens 3VA1163-4EF36-0JC0 Circuit Breaker, 63A, 36kA @ 415V","metaDescription":"Siemens 3VA1163-4EF36-0JC0 IEC frame 160 MCCB, 3-pole, 63A, Icu=36kA @ 415V, TM240 thermal-magnetic, shunt trip 110-127V, 2 aux switches.
