Hi, Dear! Welcome to our online store...
SKBB Class B AC Power Supply Lightning Protector (Limited Voltage Type)
· Generally used in LPZ1 zone and LPZ2 zone, it can reduce the residual voltage on the power grid to a large extent and dredge the simulated lightning impulse current of 8/20us. It is used to prevent low voltage equipment from being affected by overvoltage, and has a fault detection window and a remote alarm function. The protection forms of "3+0", "4+0" and "3+1" can be formed according to the different power supply systems.
· The voltage limiting type lightning arrester is generally used in the LPZ1 area and the LPZ2 area, which can greatly reduce the residual voltage on the power grid and dredge the simulated lightning impulse current of 8/20μs. The Class B power supply lightning arrester is mainly used to prevent low voltage equipment from being affected by overvoltage, and has a fault detection window and a remote alarm function. The protection forms of "3+0", 4+0" and "3+1" can be formed according to the different power supply systems.
· When the fault occurs, the detection window jumps from green to red.
· With monitoring trip device.
· Remote telecom connection (normally closed contact) as a fault indication.
