It carries a TM240 thermal-magnetic trip unit with an In of 25A. The overload protection (Ir) is adjustable from 18A to 25A, and the short-circuit protection (Ii) is adjustable from 6.4 to 12.8 times In. That adjustability lets you dial in the trip settings to match the cable and load without swapping the breaker — a real time-saver on a panel build or retrofit where the load current isn't exactly 25A. The breaker is fitted with a nut keeper kit and three HQ auxiliary switches. The nut keeper keeps the terminal hardware from backing off under vibration, which matters on a motor control center or a panel near rotating equipment. The auxiliary switches report the breaker position back to the PLC or status light, so you know whether it's tripped or open without walking the line. This breaker is designed for DIN-rail mounting inside a standard industrial enclosure. The 3VA1 series is a common choice for UL and IEC panel builds, so it fits into a wide range of switchgear and motor control center designs.","metaTitle":"Siemens 3VA1125-5EF32-0AD0 Circuit Breaker, 55kA @ 415V, 25A","metaDescription":"Siemens 3VA1125-5EF32-0AD0 IEC frame 160, 55kA breaking capacity at 415V, 3-pole, TM240 thermal-magnetic, 25A.
