The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir = 88–125 A) and fixed short-circuit pickup (Ii = 5–10 × In, so 625–1250 A), which is a standard range for motor feeders and general power circuits. ## Deployment context The 25 kA SCCR at 415 V makes it suitable for IEC distribution networks where fault levels are moderate — typical for commercial buildings, light industrial lines, and motor feeder circuits. The shunt trip allows remote tripping from a safety relay or emergency-stop pushbutton, which is common in panel-level safety circuits.","metaTitle":"Siemens 3VA1112-3EF32-0JH0 Circuit Breaker, 125A, 25kA @ 415","metaDescription":"Siemens 3VA1112-3EF32-0JH0 IEC frame 160 MCCB, 125A, 25kA breaking capacity @ 415V.
