• Suitable for maximum protection of sensitive devices in harsh environments.
• It is suitable for LEMP protection of TN-S, TN-C, TT and other power supply systems of 220V/380V (50Hz/60Hz).
• It is used at the interface of LPZOA or LPZOB and LPZ1. It is applied to the power first-level surge protection of the equipment system in areas with high lightning risk.
25KA Low Voltage Surge Protector Advantage:
• With remote signal terminal alarm function, easy to remote alarm monitoring.
• Lightning current discharge ability is strong.
• Low level of voltage protection.
• Flame retardant housing design, can be easily installed in 35mm Din rail.
25KA Low Voltage Surge Protector Working Principle:
• Under normal circumstances, the surge protector is in a state of high resistance, thus ensuring the normal operation of the power system.
• When there is a surge voltage or current on the system line, the high resistance of SPD changes to the low resistance, and SPD immediately conducts to the ground within nanosecond, releasing the surge energy to the earth through SPD.
• After the surge, the surge protector quickly returns to the high resistance state, so as not to affect the normal power supply of the system.
25KA Low Voltage Surge Protector Installation:
• Class I surge protector is suitable for LPZOA area of lightning strike or interface between LPZOB and LPZ1 area.
• It is installed in parallel in the main distribution inlet panel at the low-voltage entry end of transformer, the distribution box with overhead input in the building, the outdoor distribution cabinet/distribution box and other positions.
