These contactors provide safety function those circuits where standard contactors would
drop out the event faulty control circuit supply voltage, i.
The coil windings can energized from both a. and d. standard contactors equal rating..c.2, June 2008

Same technical data for the A110, A185 and A300 contactors with the exception of:
- coil consumption
- operating time
- mechanical durability
- mounting positions: position and prohibited (see "Technical Data" for mounting position diagram). magnetically latched contactors are very similar construction and dimensions to

- The contactor opens via the "OFF" circuit which eliminates the force from the permanent

- closing and opening the coil windings are automatically controlled through 35X 36X

The AM.
The operating coil built with windings which, when energized, create magnetic fields of
opposite directions. distribution current carrying duty. excessive voltage drops or
control circuit voltage failures.
They also provide energy saving function those circuits where contactors are used for an
uninterrupted duty, i. Only the electro-magnet and coil have specific
design order achieve the latching and de-latching operations. contactors have two resting positions, open position and latched position and
are delivered latched position..e.
