Products Information
- Integrated design,small size,expedient installation and simple maintenace. Products are applicable for interface LPZ0B-LPZ1(lightning protection zones)
- The core parts are metal oxide vanistor and Gas Discharge Tube(GDT) With high discharge capacity&reliable quality
- Low residual voltage, fast response time
- Thermo Dynamic control disconnector can automatically cutoff the circuit to protect from fire accident entirely. The flameproof & explosion-proof functions are especially applied in the fire protection situations
- Fit for TT and TN system protection against common-mode or differential-mode interferences
- Rarefied craftwork, Can work permanently in adverse conditions, such as acid, alkali, saltspray and humidity, ect.
