AM75 contactors provide a safety function in those circuits where standard contactors would drop out in the event of a faulty control circuit supply voltage, i.e. excessive voltage drops, control circuit voltage failures.
They also provide an energy saving function in those circuits where contactors are used for an uninterrupted duty, i.e. distribution or current carrying duty.
This type of contactor is particularly suitable for industrial processes where voltage sags have heavy consequences and is totally immune to voltage dips.
The AM... magnetically latched contactors are very similar in construction and dimensions to the A... standard contactors of equal rating. Only the electro-magnet and coil have a specific design in order to achieve the latching and de-latching operations.
The operating coil is built with 3 connecting terminals and 2 windings which, when energized, create two magnetic fields of opposite strength.
The coil windings must be energized from a DC supply, polarity (+ and -) must be observed.
The AM... contactors have two resting positions, closed position and open position and are delivered in closed position.
Changeover from one position to another is achieved by impulses on the coil with a minimum duration of 100 ms.
