Din Mount Surge Protector 4 pole (3Phase, Neutral and Earth) with alarm circuit.
SD-DIN series surge protectors are used to protect electrical systems from lightning and overvoltage surges in AC50/60Hz 230 /400V systems.
More Details
The product has internal non-serviceable separation device that can be replaced by replacing the replaceable modules. When the module has been exposed to a large enough over voltage or lightning strike, to permanently damage the surge protector, the internal separation device will automatically separate the protector from the electrical network and simultaneously change the green display to red to indicate the module is no longer protecting the electrical network and needs to be replaced.
Being fitted with a alarm circuit, when the indicator switches to red, the Electrical alarm circuit changes state, which in turn can be used to switch an alarm circuit and notify Building managers etc. that the Surge Diverter (SPD) needs maintenance.
