High Durability PCB Mount Relay RA1-112LM High Capacity Home Appliances
PCB Mount Relay Introduce:
RA series power relay is T-shaped with 30A at maximum range. There are PCB mounting, PCB mount, and fast terminal 250 or PCB mount and fast terminal 187 for installation. That type with QT 187 terminal, especially has enough insulation distance for the control switch, is easier to use for different users.
PCB Mount Relay Features:
1. Speed: It means that the protection device should be able to cut off the short-circuit fault as soon as possible. Its purpose is to improve system stability, reduce the damage of faulty equipment and lines, reduce the scope of faults, improve the effect of automatic reclosing and backup power supply or automatic input of backup equipment, etc.;
2. 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.
