SURGE PROTECTIVE DEVICE
Construction and Feature
Unique cartridge replacement system - easy to replace cartridge without damaging the SPD base.
Users don't need to remove the enclosure's cover when replacing the cartridge.
Signalisation of varistor's abrasion degree (green-red signalisation) indicating the replacement necessity of still functional cartridge before its final failure and disconnection of SPD.
Remote signalisation without any special preparation. To any of our SPD is possible to simply add remote signalisation accessory at any time. Old version of signalisation has to be added prior to during production, so users need to know in advance which products they will need with signalisation thus they need to keep high stock suffering from low flexibility.
