A1 A2 Contactor Coil - 21 Images

When electric current passes through the coil.

A1 a2 contactor coil. This is the heart of the contactor the magnetic coil makes electromagnetic field when rated supply reached on the contacts of the coil denoted as a1 and a2. If a1 and a2 are the coil connections on the contactor connecting an ac supply will energise it and the magnetic hysteresis will ensure that it remains energised when the supply changes direction alternates. Is the polarity of terminal a1 and a2 from contactor tesys green is a1 and a2 or can customer connect any polarity in the a1 and a2. Wiring diagram for magnetic motor starter copy contactor in electric.

220 volt circuit diagram unique 240 volt contactor wiring diagram. It reveals the parts of the circuit as simplified shapes and also the power and also signal connections between the devices. Contactor wiring diagram a1 a2 sample 2 pole contactor wiring diagram for in a1 a2 i have a 240 volt at. A1 or a2 can be swapped for both ac and dc.

If there is a freewheeling diode over the coil then the polarity of the dc voltage on a1 and a2 must match the freewheeling diode. Circuit diagram contactor best motor reversing contactor wiring. The coil gets energizes and start producing magnetic field. Fundamentally it doesn t matter which way round you connect the ac supply.
