LIVE Electrical LGF40-40P2 4-Pole 40A IP66 Photovoltaic DC Rotary Switch

Product Overview

The LIVE Electrical LGF40-40P2 4-Pole Photovoltaic DC Rotary Switch delivers robust and reliable DC isolation up to 40A, making it ideal for solar photovoltaic systems and other DC power installations. Each pole is equipped with an advanced arc extinguishing system that ensures safe disconnection by instantly eliminating electrical arcs during operation. This feature significantly extends switch life and enhances safety when handling high DC voltages.

Built to withstand demanding environments, the LGF40-40P2 features a tough, fully sealed IP66-rated enclosure for complete protection against dust and powerful water jets. The switch is engineered to comply with IEC 60947-3 standards and includes a grounding terminal for added safety. Additionally, its safety interlock ensures that the cover can only be removed when in the “off” position, preventing accidental contact with live components.
