H05Z-U / H07Z-U / H07Z-R, 90º C
300/500V for H05Z-U, 450/750V for H07Z-U & H07Z-R
Application
These cables are designed for the internal wiring of switchboards and distributor boards with an alternating nominal voltage up to 1000 Volts or a direct voltage up to 750 volts. The cables produce no corrosive gasses when burnt which is particularly important where electronic equipment is installed.
