    Product description 

    This series of small isolation switch, mainly by the insulation shell, the operating mechanism and contact system composed of three parts, the insulation shell by the high strength of flame-retardant nylon injection molding, contact for the bridge double breakpoint, the operating mechanism for the spring energy storage fast Dynamic structure. But also has the characteristics of beautiful appearance, light weight, fast breaking speed, sensitive and reliable action. This product uses the standard installation guide rail, easy assembly and disassembly, single-phase, two-pole, three-pole, four-pole can be any combination of small circuit breakers, small leakage circuit breakers. Widely used in industrial, commercial, high-rise buildings, houses and other places.

    Normal use and installation conditions
    ○ The power must be cut off before installation.
    ○ It is recommended to connect the fuse or circuit breaker in series with the lightning protection module.
    ○ Install according to the installation diagram as shown in the connection, where + for the positive line, a negative line, PE for the ground, not wrong. After the installation is complete, close the circuit breaker (fuse) switch, check the working status is normal.
    ○ After installing the module in place, check whether the anti-co-ordination module is working properly.
    ○ Lightning protection module during use, should regularly detect and view the fault display window status, when the fault display window is red or remote signal output terminal alarm signal, that lightning module i barrier should be repaired or replaced in time.
    ○ parallel power lightning protection modules should be installed in parallel, the connection line requirements solid and reliable, and require short, thick, straight.
