● The SPD is single-port, electric shock protected, indoor fixed mounting and voltage limiting type.
● The SPD is built with a disconnector. When the SPD fails due to overheating or breakdown, the disconnector can automatically disconnect it from the power grid and send out an indication signal. The viewing window is white during normal operation and turns red after failure and disconnection.
● 1P+N, 2P+N and 3P+N types consist of 1P, 2P, 3P SPD and NPE neutral-earth protection modules, suitable for TT, TN-S and other power supply systems.
The LYD5-150T surge protector is an integrated product, applied for Class B surge protection of three-phase power in low-voltage AC power distribution systems such as TT, TN-S and IT. With integrated design, it provides two protection modes: L-PE/N-PE and L-N/N-PE. It features large discharge capacity and low residual voltage. The integrated structure enables easy installation. The protector is equipped with thermal disconnection and light alarm function, and remote signal contacts can be added upon customer request.

● Class B lightning current SPD protection, applied for equipotential connection during lightning strikes.
● It is generally installed at the low-voltage main incoming distribution cabinet for overhead line inlet.
● The protector is mounted on standard 35mm DIN rail.
● The model, specification and quantity of SPD shall be specified when ordering.
● 10~35mm² copper wires are used for protection connection, and multi-strand flexible bicolor copper wires above 16mm² shall be adopted for grounding.
● To prevent the safe operation of power grid from being affected by failed surge protectors, a matching LYSCB backup protector must be connected in series at the front of each pole SPD.
