Buying a voltage surge protector The important thing we should take consider this.

1. Features of Surge Protective Device

     - Surge Current Capacity is defined by the NEMA standard, which represents the highest level of current that a surge protector Momentarily it can withstand high voltage for a while. This level of electricity will indicate the ability of the device to protect. And used in the selection of equipment. Suitable for use in areas such as open areas, which are vulnerable to severe lightning. To consider The highest electrical level of the device. High enough to resist.

     - Clamping Voltage is a feature that refers to the peak that allows the voltage to flow. Or say that. It is the voltage that the surge protective device temporarily transmits to the connected electrical equipment at the moment of high voltage. This feature is used to measure the ability to reduce the voltage in the shortest time of the device, which is UL Certified.

2. Safety Consider

     - Surge Protective Device Fuses or circuit breakers should be installed in the circuit to be protected. To negate the MOV that may be damaged during the high-voltage period. Or to prevent over-power.

     - In case of high voltage rise Surge Protectors must be protected in such a way as to connect Line Line to Neutral Line Line to Ground Line, Line Line to Line Line and Neutral Line to Ground Line, etc.

      - Surge Protective Device There are lights or alarms. There is a Surge counter to display the status while the surge suppressor is activated.
