LIVE Electrical LGF40-25P2 4-Pole 25A IP66 Photovoltaic DC Rotary Switch

Product Overview

The LIVE Electrical LGF40-25P2 4-Pole Photovoltaic DC Rotary Switch is a high-quality isolator designed for safe and efficient disconnection of DC circuits up to 25A. Each pole is fitted with an advanced arc extinguishing system that instantly suppresses electrical arcs during operation, ensuring long-lasting safety and reliability. This makes the switch ideal for solar PV systems, battery storage, and DC distribution applications requiring dependable isolation and protection.

With its rugged IP66-rated enclosure, the LGF40-25P2 is completely dust-tight and resistant to strong water jets, making it suitable for both indoor and outdoor installations. It also includes a grounding terminal for enhanced electrical safety, and the cover can only be removed in the “off” position to prevent accidental contact with live parts. Built to IEC 60947-3 standards, this rotary isolator is engineered for superior performance and durability in demanding environments.
