>Product Overview
The CZD5 series surge protector is suitable for use on AC 50/60H2, 380V and below in TT, IT, TN-S, TN-C-S and other power supply systems, and can be used as an equipotential connection at the interface of LPZ1, LP22 and LP23 zones. The housing is designed to be mounted on a 35mm electrical rail. The product has a built-in failure disengagement device, which automatically disengages the surge protector from the grid when it fails due to overcurrent, overheating or breakdown, and at the same time visualises the alarm, when the module turns from green (normal) to red (fault).
Product conforms to standards: IEC61643-1, GB/T 18802.1.
