Power Relays, Over 2 Amps: HJ4-AC220/240V-6

The HJ4-AC220/240V-6 is a power relay from a series of HJ series with a rating of 240-V. This relay is rated for over 2 amps and can be used in a variety of applications. It\'s purpose is to control electrical loads such as motors, lighting systems, and pumps.

Application Field

The HJ4-AC220/240V-6 is suitable for power control in a wide variety of applications. It can be used to control motor loads in commercial and industrial equipment such as household appliances, HVAC systems, and security systems. It is also used to control lighting systems and pumps. The HJ4-AC220/240V-6 can also be used in building automation systems, such as for temperature control, window/door control, and lighting control.

Working Principle

The HJ4-AC220/240V-6 is a four-pole, two-throw (4P2T) relay. It works on a simple principle of energising and de-energising. When the relay is energised, a magnetic coil produces a magnetic field that causes the armature, which is on the centre core of the relay, to move and completes the connection thereby switching on the load. When the relay is de-energised, the armature lifts off the centre core and it breaks the circuit and the load is switched off.
