Why Choose the GD040AT4?
Engineered for safe DC isolation in solar systems, the Lovato GD040AT4 switch disconnector delivers reliable performance in photovoltaic applications. This direct-operating, 2‑pole unit comes complete with a black handle and supports up to 1500 V DC with Ui 1500 V and Uimp 8 kV. Rated 40 A at 1000 VDC, 32 A at 1200 VDC, and 25 A at 1500 VDC, GD040AT4 ensures dependable disconnection.
Flexible mounting on 35 mm DIN rail or screw-on plate simplifies installation in enclosures. With IP20 frontal protection, 10,000 mechanical cycles, and operation from −25 to +55 °C up to 3000 m altitude, it is built for demanding sites. Screw terminals accept 1–10 mm² conductors with 1.2–1.6 Nm tightening torque for secure, low-loss DC connections.
