The TM240 thermal-magnetic trip unit gives adjustable overload protection from 175A to 250A and fixed short-circuit protection set at 5 to 10 times In. The adjustable Ir (175–250A) lets you dial in the cable or busbar ampacity without swapping the breaker — useful when the connected load isn't exactly 250A. ## Deployment context This is a panel-mount breaker for fixed or plug-in installation in distribution boards and motor control centers. The 4-pole configuration with 50% neutral protection makes it suited for three-phase systems where the neutral conductor is sized smaller than the phase conductors — common in commercial and light industrial panelboards. The nut keeper kit simplifies busbar connection during assembly.","metaTitle":"Siemens 3VA1225-6FF42-0AF0 Circuit Breaker, 250A, 70kA @ 415","metaDescription":"Siemens 3VA1225-6FF42-0AF0 IEC frame 250 circuit breaker, 70kA breaking capacity at 415V, 4-pole, TM240 trip unit.
