Product Description

Product Description

 

HCH series Household AC Contactor (also called modular AC Contactor), is mainly used in power systems with current 50Hz/60Hz, rated working voltage up to 400V, and rated working current up to 100A. Under the AC-1, AC-7a (No-inductive or low-inductive load, resistance furnace, household appliances or low-inductive load for similar purposes) usage category, it can be used as remote switch and control circuit, and also can be used to control household motor load. Household AC contactors are not used to break short-circuit current, so appropriate short-circuit protection appliances (such as Micro Circuit Breaker) should be selected when in use. Compliance with IEC61095, GB17885 standards.
AOCT Household AC Contactor has expandable auxiliary control, protection and indication functions. Mainly used in homes, hotels, apartments, office buildings, public buildings, shopping centers, stadiums and other places.

Note: When the contactor is installed in the distribution box, spacers must be assembled on both sides to facilitate heat dissipation.

Working principle.When the coil is electrified, the coil current generates magnetic field, which generates enough electromagnetic suction to overcome the reaction force, and the armature is sucked in to make the contact connected. When the coil voltage disappears or the coil voltage will be low to a certain value, that is, when the so-called release voltage, the magnetic flux generated by the armature end surface decreases, the electromagnetic suction begins to be smaller than the reaction force produced by the reaction spring and the contact spring. The armature of the contactor is released under the action of this reaction force, leaving the yoke, and the contact breaks off immediately.
