Product Types Selection

1. The nominal voltage of the gas discharge tube in the DC ci is selected to be 1.8 times the working voltage: in the AC circuit, it is selected to be 2.5 times the effective value of the working voltage.

2. The nominal current capacity of the gas discharge tube should be greater than the maximum possible surge impact capacity of the protected circuit.

3. Due to the freewheeling of the gas discharge tube, the gas discharge tube generally cannot be used in a DC circuit unless the DC working voltage is lower than the breakdown voltage of the gas discharge tube.
