EHDT Load Break Switch(1500V,400A,630A,800A 2P)
DC load Isolator Switch with IEC standard,Available from 160A-250A-630A(DC20) in 4P version, acting as a load break switches for DC current. Especially indicated for installations for photovoltaic energy generators, which require a safe disconnection. Standard handle is supplied pad lockable in position "OFF" for maintenance. Bridging links available for series connections.
Easy to install
Wiring: Since the switch is non-polarized, all types of wiring and connections are possible.
Easy access without tools, and auxiliary contacts can be integrated without tools.
