Power relays, especially over 2 amps, are used in a wide variety of applications. In some cases, they are used to switch large current loads or solely for controlling circuit switching. In this article, we are looking at the MJN3C-N-AC120 power relay, its application field and working principle.

The MJN3C-N-AC120 power relay is a 24V DC operated coil with a 5A contact rating. This relay is suitable for simple ON/OFF applications, such as lighting, motor control, pumps, and solenoids. The contact rating is 5A at up to 120V AC.

The MJN3C-N-AC120 can be used as a direct replacement for existing power relays in industrial applications such as machine tools, material handling, motor drives, industrial automation, and other 24V DC applications. The contact material is made up of a silver-nickel alloy, which is extremely resistant to arcing and welding, and has an exceptionally long life. It also has a long-term temperature rating of 105°C.

The MJN3C-N-AC120 is ideal for applications where size and cost are the primary considerations. The compact size of the relay enables it to be used in a wide range of engineering products that require higher switching capacities. It is also suitable for applications that have a limited number of contacts.

The working principle behind the MJN3C-N-AC120 relies on the use of electromagnets. When the coil is energized, the magnetic force of the electromagnet moves the armature from the normally open to the normally closed position. This opens or closes the contacts of the relay. When the coil is de-energized, the force of the armature spring returns the armature to its original position, thus opening or closing the relay contacts.

The MJN3C-N-AC120 relay is a reliable and effective solution for applications requiring power switching and relay control. It is robust and compact, and offers excellent performance and long life. It is also suitable for use in applications that require higher switching capacities, such as motor drives and industrial automation.
