Products Information
Features of Surge Protective Device:
- Integrated design, small size, expedient installation and simple maintenace are the distinguished features of our power surge protector. 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 status indicator can indicate operating status syllabify and straightly. Remote alert function makes your control easy
- 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.
