This page shows how to turn scattered MOV, GDT and TVS parts into a coordinated surge and lightning protection concept, from threat levels and device selection through multi-stage SPDs, monitoring, layout and maintenance so that substations and smart LV panels stay stable.

This page shows how to turn scattered MOV, GDT and TVS parts into a coordinated surge and lightning protection concept, from threat levels and device selection through multi-stage SPDs, monitoring, layout and maintenance so that substations and smart LV panels stay stable during real storms. This. The REC615 and RER615 are grid automation protection and control relays for remote control and monitoring, protection, fault indication, power quality analysis and automation in medium-voltage secondary distribution systems. These devices can be applied to new or already existing secondary. Surge protection plug, directly pluggable on 2 terminal blocks, with integrated status indicator on the module for a 2-wire floating signal circuit with high nominal current. Nominal voltage: 230 V AC Transmitter module, for the visual monitoring and floating remote signaling of adjacent surge. With integrated ACI switch/spark gap and RADAX Flow technology for maximum system availability. Maximum system availability thanks to RADAX flow follow current limitation. Designed to simplify deployment and take stress out of power distribution, this intelligent PDU helps reclaim valuable hours. Whether that means speeding up Saturday installs or focusing on. While our heritage is in venues like Madison Square Garden, the Austin City Limits Stage at the Moody Theater and the like, our future is everywhere there are ο¬at panel displays, screens, cameras and LED lighting to control.
