Magnetic Latching Contactors (GCR1-F)

Magnetic latching contactors of both block and bar mounted types are fitted with a special electromagnet which enables them to remain in the "On" position when the coil is no longer energised.

Applications

The special properties of magnetic latching contactors make them suitable for a large number of applications.

■ Refineries, power stations, excitation circuits.
■ Contactors remaining in the closed state for long periods.Examples:refineries, power supplies,low voltage distribution.
■ Selective opening control.
■ No unwanted opening and closing of the main power poles.
■ Current carrying at voltages up to 1000 Volts.

Properties

■ Retention of the sequence memory in automatic control equipment in the event of loss of control voltage.
■ Energy saving, since the source of supply to the coil does not need to supply current when the contactor is latched in the
    closed state.
■ Change of state from "Closed" to "Open" by current signal through the coil.
■ Unaffected by mains interference.
■ Utilisation of contactors beyond their breaking capacity, as operations are performed off-load.
■ Contactors are silent in the latched position.

Operation of the electromagnet (GCR1-F block contactors)

■ GCR1-F magnetic latching contactors are fitted with a double coil with 3 terminals comprising a latching winding and an
    unlatching winding. The 2 windings have a common point which can necessitate special wiring precautions when the
    latching supply is separate from the unlatching supply.
■ The power supplies may be a.c. or d.c. For d.c. operation, the polarities indicated must be complied with.
■ Operating precautions:the 2 windings must not be supplied simultaneously,a winding must not be supplied
    continuously,supply to the coils must be via pulsed contacts.
■ Manual opening: if the control voltage is not present, the contactor can be unlatched manually.
