PV Photovoltaic DC Switches

KATKO’s PV switch is used to break direct current so that solar panels or an inverter can be safely isolated for maintenance. PV switch can be installed for individual panels or a string of panels. Made of self-extinguishing material the Katko Photovoltaic (PV) isolators have been developed to be durable under difficult climatic conditions and require no extra protective coating. Ranging up to 32A 1200V DC, DC21B - The Katko range has been built in order to ensure safety, reliability and performance. With superior temperature performance including good resistance against UV and many chemicals. The Katko photovoltaic range is excellent for Solar Panel systems. Dalroad is an authorised distributor of KATKO products. For further information regarding specific DC switches, see product data sheets below or contact our dedicated sales teams for a quote.
