Hager ES110 239110 20A / 250VAC, 230VDC, 1x NO contactor

Contactor allows to control large currents with small controlling current. Contactor is almost the same as relay or solenoid, but usually when speaking about contactors it refers to something larger than relay. Contactors auxiliary contacts may be used to create latch circuit or safety feature that for example prohibits activation of other contactor while in first is activated.
