DC isolator switch for disconnecting the DC circuit and controlling the PV installation; up to 1000V / 32A, with handle, with valve, for safe use and maintenance. Can be widely used in residential and commercial solar PV systems. It is the first DC switch compliant with AS 60947.3:2018 DC-PV2 standards and can be used worldwide in PV DC systems. Features: 2 poles, 1000V DC, 32A. No polarity. Fire retardant and UV resistant. The switch is locked in the off position. Arcing time less than 3ms, that make PV solar system effectively disconnected. A breathing valve shall be attached on the DC isolator. Pre-wired MC4 in factory avoid the loose wiring or failure installation. The DC isolator switch is wired with MC4 for faster and safer installation.
