The TM240 thermal-magnetic trip unit provides adjustable overload protection from 70 A to 100 A (Ir) and fixed short-circuit protection set at 5 to 10 times In (Ii). This variant includes a nut keeper kit, configured for a DC Power OEM application in China. For a 415 V distribution board feeding motor control centers or transformer secondaries, this rating handles the prospective short-circuit current typical of a 1 MVA to 2 MVA transformer secondary. The 100 A frame and adjustable Ir (70–100 A) let you size the overload to the actual load, not the frame max, avoiding nuisance trips on a 75 A conveyor drive or 80 A pump feeder. ## Deployment context The nut keeper kit indicates the breaker ships with captive hardware for the DC Power OEM's busbar or cable lug connections — a detail that saves panel-build time compared to sourcing loose hardware.","metaTitle":"Siemens 3VA1110-4EF32-0AA0-ZD00 Circuit Breaker, 36kA @ 415V","metaDescription":"Siemens 3VA1110-4EF32-0AA0-ZD00 IEC frame 160 circuit breaker, 36kA breaking capacity at 415V, 3-pole, TM240 overload protection 70-100A.
