Detailed Product Description

Application scope

The normal operating condition
1. The altitude should less than 2000m
2. Ambient temperature: normal range: - 5~+40C. Extension range: - 40~+70C
3. Relative humidity: room condition: 30%~90%.
4. No obvious shock and impulse vibration
5. No dangerous explosion medium, and there's no gas and dust which can make metal rust and destroy the insulation ( including electric dust)

Usage
Voltage limiting type SPD combined with voltage switching type SPD is formed the Group SPD, which is suiting to A.C 50/60 Hz , 380V and under 380V voltage's electric power system and protects all the distribution systems shocked by the thunder or surge over voltage.
Using the combination SPD between phase line and earth line in the distribution system, which not only eliminates the power-frequency continuous current, but also over comes the leakage tripping which results from the bad performance of MOV. So SPD is suitable to all the distribution system which is with the protection of surplus current. Since the voltage switching SPD is connected between zero line and earth line, at the same time with its much higher maximum continuous operating voltage and enough impulse current capacity, it will have its peculiar superiority when used in TT system.

Remote signaling contact
SPD can be connected with remote signaling contact, which is a normal close contact ( the end with H) or normal open contact ( the end with K). If one or more of modular of the protector is in malfuction, the contact will be closed, and sending the malfunction signal.The rated value of remote signaling contact is 125V~1A.
