Ag AgNi Power Control Relay SPST Or SPDT Feature Class F Insulation
Overload Protection 12V 50A Relay BS4-12S-C20 Class F Insulation Class
12V 50A Relay Introduce:
The relay is kept in the released state by the permanent magnet. After the working voltage is applied, the electromagnetic induction makes the armature and the permanent magnet generate an attractive and repulsive torque, resulting in a downward movement, and finally reaches the state of attraction. When the relay is working, the electromagnet is energized, the armature is sucked down to contact, and the working circuit is closed. When the electromagnet is powered off, it loses its magnetism, and the spring pulls up the armature to cut off the working circuit. Therefore, the relay is a switch that uses an electromagnet to control the on-off of the working circuit.
12V 50A Relay Features:
Selectivity: It means that the protection of the faulty equipment or the line itself should remove the fault first, and only when the protection of the faulty equipment or the line itself or the circuit breaker refuses to operate, the fault can be removed by the protection of the adjacent equipment, the line or the protection of the circuit breaker failure.
