The thermal-magnetic TM240 trip unit gives you adjustable overload protection from 70 A to 100 A (Ir), and short-circuit pickup (Ii) from 5 to 10 times the rated In of 100 A. That adjustability means you can dial it in for a specific motor or feeder load without swapping the breaker body. The TM240 trip curve is thermal-magnetic — the thermal element handles overloads with a time delay, the magnetic element trips instantaneously on short circuits. Setting Ir between 70 and 100 A lets you match the breaker to a 100 A feeder or a motor with a lower FLA, and the Ii adjustment of 5-10x In gives you selectivity headroom against downstream branch breakers.","metaTitle":"Siemens 3VA1110-5EF42-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1110-5EF42-0AA0-ZD00 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 4-pole, TM240 thermal-magnetic trip, In=100A.
