GE1250DT4 - 4P SWITCH DISCONNECTOR FOR DC DUTY

Why Choose the GE1250DT4?

Engineered for demanding photovoltaic isolation, the Lovato GE1250DT4 is a four-pole DC switch disconnector delivering a robust 1250 A Ith with a 1000 V Ui rating. This direct operating and door-coupling version supports flexible panel layouts and secure screw-on plate installation. With IP20 frontal protection and Pollution Degree 3 suitability, it ensures dependable switching and isolation in high-current DC systems across commercial and utility-scale solar deployments.

Built for longevity and compliance, this GE series isolator offers 10,000 mechanical operating cycles and a 12 kV impulse withstand voltage. It operates reliably from -25 to 55 °C and up to 3000 m altitude. Conforming to IEC/EN 60947-1 and 60947-3, its four-pole DC architecture suits PV arrays and DC switchboards, providing safe disconnection and clear isolation within panel enclosures.
