Main features and installation method
※ Fast response speed, less than 100 nanoseconds
※ Low limit voltage
※ Large flow capacity
※ Normal white, invalid red
※ Can be installed by Kevin wiring
※Class B lightning current HD-DLY protection, used for equipotential connection during lightning strike
※ In order to prevent product deterioration from affecting the normal power grid, the corresponding specification circuit breaker or fuse must be installed in the front section
※ Parallel installation at the incoming low-voltage main distribution cabinet, an overhead incoming line
※ Protector adopts standard 35mm track
※ Please specify the model, specification and quantity of HD-DLY when ordering
※ The protection shall be connected with a copper wire of 10~35mm2, and the grounding wire shall be a two-color wire of 16mm2 or more.
