ST25-20 – 25 A modular contactor with a 230 V AC coil
The ST25-20 is a compact electromagnetic contactor designed for switching electrical circuits on and off. Applying voltage to the coil causes two normally open contacts to close, and when the voltage is removed, the contacts return to their rest position.
The single-module design helps to minimise the space required in the switchboard. The switching status is indicated by a marker on the housing.
