The MJN3CF-DC12 power relay is typically used for applications requiring over 2 Amps of current in the switched circuit. It is a small, compact, and low cost unit with a load capacity up to 16A, making it ideal for a range of applications from home and industrial automation, smart meters, and lighting control to monitoring systems and industrial instrumentation.

The MJN3CF-DC12 is a single, pole double throw (SPDT) type relay, meaning it has two independent switching contacts that are controlled by a single coil. The contacts are normally open (NO) when the coil is de-energised, and closed when the coil is energised. This type of relay is typically used for logic switching and signal transmission applications.

The MJN3CF-DC12 is designed to operate with a maximum switching current of 16A, a maximum switching voltage of 250VAC, and a minimum operating voltage of 5V. It has a low power consumption of less than 500mW and a response time of less than 11ms. The operating temperature range is from -40°C to 85°C and the insulation resistance is greater than 100MΩ. The MJN3CF-DC12 has a maximum current range of 200mA- 16A and a maximum voltage range of 250VAC. The relay has a life expectancy of more than 10,000,000 operating cycles.

The primary components of the MJN3CF-DC12 are two contact plates, a control coil, an armature, an armature housing, and a frame. The two contact plates are what closes and opens the circuit when the relay is energised and de-energised, respectively. The control coil is the magnetic field source that is used to move the armature, which in turn opens and closes the contact plates. The armature and the armature housing together form the movable electrical contact, while the frame serves as the support structure for all the components.

When power is applied to the control coil, the magnetic field generated attracts the armature towards it. This causes the armature to move and make contact with the appropriate contact plate for the desired circuit. When the current to the coil is removed, the magnetic field dissipates and the armature springs back to its original position, closing off the circuit and disconnecting the contact plates.

The MJN3CF-DC12 is commonly used as a control component for on/off switching and signal transmission in various types of automation systems. It is also used in applications where the contact switching is vital for maintaining the safety and proper function of the system, such as in smoke detectors, security systems, and industrial process control.

The MJN3CF-DC12 is a reliable and cost-effective solution for any application requiring more than 2 Amps of current in the switched circuit. It is easy to mount and requires minimal maintenance. With its low cost, small design, and long life expectancy, the MJN3CF-DC12 is a great option for any application that needs more than 2 Amps of current without compromising performance or reliability.
