All the main ranges of Albright contactors are now available with magnetic latching - one short pulse to close the main contacts - one short pulse to reopen them again.

The result is a bistable device, the coil of which consumes no power except during the closing and opening strokes and because there is in effect no heating of the coil, the contactors can be engineered in the first place with more powerful coils and springs than with conventional contactors.

Contact ratings and all external dimensions are identical to those of the equivalent types which have conventionally energised coils. Similarly all the additional features which are available with Albright contactors can be found with the magnetically latched versions, eg auxiliary contacts, magnetic blowouts for the main contacts, wide selection of brackets, and such like.

The magnetically latching contactors can be driven directly from a reversible power supply. Alternatively the Albright ML52 or ML53 coil controller can be utilised.

Please Note, Very Important: Magnetically Latched Contactors do not fail safe. If there is a power failure, or if the supply to the contactor coil is broken, the contactor contacts will not open or close, i.e. they will not change state. These devices should not therefore be used in applications where the failure of contacts to open or close could result in a hazardous situation for persons or equipment.

Interested parties are advised to contact Albright, or an appointed distributor, to discuss their requirements further.
