● This product is a single-port, indoor fixed-installation voltage switching type SPD. It is designed in accordance with current national standards such as GB50057-2010 and GB18802.1. It features high impulse current (Iimp: 30kA) and low residual voltage (Up: 2.5kV). Its core components consist of multi-stage graphite gaps. Through reasonable design and precise processing, the spark gaps are integrated to form a sealed structure, ensuring the safe distance inside the spark gaps. No arc leakage will occur even when surge current passes through, so no special space for arc leakage is required during installation. The product quality is stable and reliable.

● The product is installed at the junction of LPZ0A / LPZ0B zone and LPZ1 zone, or at the main distribution box (cabinet) for power incoming, mounted on 35mm standard DIN rail. Connecting wires adopt 6~35mm² multi-strand copper flexible cables.

● The grounding wire shall use bicolor wires with cross-section ≥16mm² and length ≤500mm.

● To prevent the failure of surge protective devices from affecting the safe operation of the power grid, a matching LYSCB backup protector shall be connected in series with the protector connected to the L line.
