Overload protection uses a TM240 thermal-magnetic trip unit, adjustable from 18 A to 25 A (Ir), so you set it to the exact load current. Short-circuit pickup Ii adjusts from 6.4 to 12.8 times In — 160 to 320 A at the 25 A setting — which lets you coordinate with downstream branch breakers and avoid nuisance trips on motor inrush. The 3VA1 frame accepts DIN-rail or rear-panel mounting; the nut keeper kit (included) secures the breaker in a panel without loose hardware rattling around during transport or vibration.","metaTitle":"Siemens 3VA1125-3EF32-0DC0 Circuit Breaker, 25A, Icu=25kA @","metaDescription":"Siemens 3VA1125-3EF32-0DC0 IEC frame 160 circuit breaker, 25A, Icu=25kA @ 415V, TM240 overload, UVR 208-230V AC.
