VFD Panel Lightning Protection

A Type 2 Lightning Surge Protection Device is installed at the VFD panel 3Phase power breaker. This has a Frequency Response Circuit to filter the peak of lightning induced current and EMI/RFI in the power line. The unit filters the residual voltage left from the Main Panel Type 1 device. The unit is supplied in a NEMA4X enclosure for outdoor installation. It has LED indicators for each phase. The unit comes standard with a dry relay contact cable that can be connected to the facility SCADA system. This allows remote monitoring of the unit’s integrity.
