GE1250 - 3P SWITCH DISCONNECTOR

Why Choose the GE1250?

Built for demanding switch disconnector duties, the Lovato GE1250 switch disconnector delivers dependable three‑pole AC isolation and switching at 1250 A Ith. With Ui 1000 V and Uimp 12 kV, the GE1250 suits plate‑mounted panels requiring IP20 frontal protection and robust performance. Conditional short‑circuit current is 72 kA with gG1250 fuse protection, supporting safe operation in industrial power distribution where reliable on‑load disconnection and isolation are essential.

Performance spans AC21A 1250 A at 400/500 V, AC22A up to 1250 A at 400 V, and AC23A up to 1000 A at 400 V. Rated operational power reaches 443 kW at 400 V AC23A and 478 kW at 690 V. A 10,000‑cycle mechanical life, −25 to 55 °C operation, 45 Nm terminal torque (max), 3000 m altitude and Pollution Degree 3 underline durability. Conforms to IEC/EN 60947‑1 and 60947‑3, with Sustainability certification.
