120kA Lightning Surge Protectors (SPD)

120kA Lightning Surge Protectors (SPD)

LYD5-150T type surge protective device is the integrated product, suitable for being used in TT, TN-S, IT and low voltage AC distribution system and provide B class surge protection for three phase power supplies. Integral design is adopted, the protection mode divided into two kinds: L-PE/N-PE, L-N/N-PE, with such advantages of large carrying capacity, low residual voltage, integral structure make installation easily, the protector has thermal tripping and light alarm, remote signal can be provided if user required.

Operation elements

1. Fast response time, less than 25ns.
2. Low limited voltage.
3. Large current carrying capacity.
4. Normal state is for white color and red color is for invalid state.
5. Kelvin wiring mode available.

The contacts:

SPD can provide the NO contact for remote communication, if one or more modules of SPD is invalid, the NO and NC contact will be closed and send fault information.

Installation:

1. Category B surge protective device (SPD) used in the connection between equal potential electrodes while thunder occur.
2. Generally to be installed in low voltage main incoming distribution panel, overhead incoming.
3. To adopt 35mm standard mounting rail for SPD mounting.
4. When to place an order, please indicate the model, specifications and quantity.
5. It shall adopt 10 to 25mm² copper conductor to be connected with SPD, earthing wire shall be dual color multi-standard soft copper conductor more than 16mm².
