FIELD: electricity.
SUBSTANCE: contactor for operation on DC and AC currents is equipped with at least one contact part made of a fixed contact and a movable contact; at least one permanent magnet placed near the contact part and intended to develop a permanent magnetic arc-quenching field and at least one coil placed near the contact part and intended to develop an electromagnet arc-quenching field to suck-in the arc that originates when the contact part opens at least into one arc-quenching chamber. The contactor is also equipped with at least two contact parts, movable contacts of which are placed on the contact bridge; at least one permanent magnet placed near each contact part, besides, permanent magnets related to two contact parts are polarised in opposite directions.
EFFECT: provision of fast and reliable opening of contacts and arc-quenching, simplified design and manufacturing.
