Power relays are electrical devices that are used to control power in a variety of different applications. The MJN3C-AC12 power relay is a reliable and efficient solution for controlling and switching high voltage and high current loads. This device is suitable for a variety of electrical applications, especially those involving power switching and/or power switching and current sensing. This Relay is designed tooperate at voltages of up to 1250V with currents up to 5A (depending on temperature). It also has operational temperature ratings ranging from -40°C to 120°C, making it suitable for use in a variety of environments.

The MJN3C-AC12 power relay is a three-pole, double-throw switch. It has a metal oxide varistor (MOV) that protects the switch from transient voltage. The relay is provided with a surge arrestor to limit the current and to avoid accidental actuation in the event of a short circuit. It also has a built-in thermal fuse for safety. Additionally, the relay has an LED indicator that shows the status of the contact closure. This can be used to identify when the relay has been triggered.

The MJN3C-AC12 power relay also has a wide range of applications due to its adjustable setpoint. This setpoint can be adjusted from 0. 5A up to 5A. This allows the relay to be used for applications that require a wide variety of current settings. The setpoint can be adjusted using trimmers, which are provided with the device.

The working principle of the MJN3C-AC12 power relay is relatively simple. When the voltage across the relay contacts exceeds a certain setpoint, the contacts close and the current flows through the relay. This current then triggers the internal MOV, which protects the relay from any sudden voltage overloads. If the overload continues, the thermal fuse will be activated and the current will be interrupted.

The MJN3C-AC12 power relay is a reliable and efficient power switching device. It can be used in a variety of applications, such as in power supplies, DC motors, AC motors, solar cells, and other applications where high current and high voltages are required. Additionally, the adjustable setpoint allows it to be used in many different applications, making it a versatile and reliable power switching device.
