DC switching

In photovoltaic systems, the open P-SOL and enclosed SOL switch-disconnectors from Eaton’s Moeller series safely switch off DC currents between the PV generator and the inverter. These special devices are highly versatile and cover operating currents of 20 A, 30 A and 63 A at 1,000 V DC. As no polarity is specified, they can be installed across a wide variety of distribution systems. In addition, the switch-disconnectors can also be used as a separate switching element, for example to safely disconnect a defective inverter from the power supply. And as 2-pole switches, they are also suitable for unearthed systems. With their pre-wired, out-of-the-box functionality and IP65 enclosure, they are also ideal for outdoor use.

P-SOL DC switch-disconnector

Our P-SOL open switch-disconnectors are intended for customised enclosures or inverters. Separate rotary handles and shaft extensions enable flexible installation. An auxiliary contact can be attached for indication of the switch state. A shunt release module and an undervoltage release module are available for remote tripping.

SOL DC switch-disconnector

Our SOL switch-disconnectors are available as two- and four-string versions and with the two most commonly available connector types. MC4 or metric cable glands allow for hassle-free integration into different system designs. An integrated pressure compensation element prevents condensation to protect against malfunctions due to flashover.
