Products Information
Features of Transient Surge Protection:
- Integrated design, expedient installation and simple maintenace. This kind of transient surge protections are applicable for interface LPZ0B-LPZ1(lightning protection zones)
- The core parts are metal oxide vanistor with high discharge capacity & reliable quality. The maximum discharge current Imax is up to 60kA(8/20μs)
- 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
- Products can be connected in parallel to fit for various power nerwork systems
- Plug-in protection module can be replaced easily when it is failed
