MT331220

MT331220 Application Field and Working Principle

MT331220 is a power relay belonging to the category of power relays over 2 Amps, which offer electrical isolation between its input and output circuits. These relays have in-line construction with separate contact blocks and are ideal for use in applications requiring high inrush capacity, high switching capacity and multiple contact blocks. The main application field of MT331220 is for LED lighting and electronics, including the automotive, medical, chemical and consumer appliance industries.

Working Principle

The MT331220 power relay works by using an electromagnetic field to create a closed circuit between two points in a circuit. When electric current passes through a coil, magnetic field is created; when the coil is exposed to an exterior magnetic field, the coil produces electricity. MT331220 contain a coil, a coil frame, an armature and a contact mechanism. The coil is located within the core of the armature; the armature fasteners are then connected to the contact mechanism.

When a current is passed through the coil, a magnetic field is generated around the core. This causes the armature to move and the fasteners to move along the slot in the coil frame closing the contact mechanism, creating a physical connection between two points. When the current is removed, the armature moves back and the connection is broken. This enables the MT331220 to be used for switching power circuits.
