The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir = 70 A to 100 A) and fixed short-circuit protection (Ii = 5 to 10 x In), so it covers motor and feeder circuits where you need to dial in the exact load current. The built-in undervoltage release (24 V DC) and two auxiliary changeover switches make it a drop-in for safety circuits that need to drop the breaker on loss of control voltage, plus remote status indication. ## Deployment context Mounts on a DIN rail in a standard panel enclosure. The nut keeper kit simplifies panel assembly by retaining mounting hardware during installation.","metaTitle":"Siemens 3VA1110-4EF42-0BH0 Circuit Breaker, 100A, 36kA @ 415","metaDescription":"Siemens 3VA1110-4EF42-0BH0 circuit breaker, 100A, 36kA breaking capacity @ 415V.
