Power relays can be used to control high-power circuits with an electric signal. The MJN3C-AC120 is a power relay designed for either AC or DC circuits, capable of switching up to 120 Amps of current. It has a single contact with all three contact forms available (NO, NC and changeover) to make it more versatile.

The MJN3C-AC120 is a general-purpose power relay with a 180-VAC and 250-VDC rated voltage, and an AC3 rating of 90 Amps/660V and a DC2 rating of 120 Amps/250V. It also has a 2kV dielectric strength and a 9kV impulse strength. Its power consumption is only 0.4 VA and its life cycle is 400,000 times. It also offers reverse polarity protection for extra safety in case of accidental wiring errors.

The MJN3C-AC120 has a number of applications. It is commonly used in automotive, industrial, general-purpose, and aerospace/military applications. It is commonly used in the circuit control of HVAC equipment, servo motors, elevators, and other similar equipment. Additionally, it is well-suited for applications where electrical noise must be minimized.

The MJN3C-AC120’s working principle is based on the electromagnetic relay principle. When the control signal is turned on, a coil inside the device gets energized, creating an electromagnetic field. This field attracts the armature located inside the device, causing it to move and the contact to be switched from the normally open (NO) to the normally closed (NC) position. Conversely, when the control signal is turned off, the coil is de-energized and the armature returns to its original position.

The MJN3C-AC120 is powered by either AC or DC current, making it versatile for a range of applications. It has excellent anti-interference performance, high protection level and electric strength. It is also highly reliable and shock resistant. Furthermore, its small size and low power consumption makes it preferable in areas where space is at a premium, such as in automotive and aerospace. This relay is also easy to install and maintain.

The MJN3C-AC120 is a reliable and versatile power relay with a high current rating and low power consumption. It is well suited for applications needing reliable switching over a wide range of AC and DC currents. Its small size and excellent anti-interference performance make it a great solution for tight spaces such as automotive and aerospace where reliability and shock resistance are essential.
