Products Information
Features of Surge Protective Device:
- Expedient installation and simple maintenace. Products are applicable for interface LPZ0B-LPZ1(lightning protection zones).
- The core parts are metal oxide vanistor with high discharge capacity & reliable quality. The maxmum discharge current Imax is up to 120kA(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.
- Kelvin wire connection method can reduce inductance and residual volatage. Multiple Products can be connected in parallel to fit for various power nerwork systems.
