GE0250T4 - 4P SWITCH DISCONNECTOR

Why Choose the GE0250T4?

Lovato’s GE0250T4 is a GE series four‑pole switch disconnector engineered for dependable AC isolation in control panels and power distribution. With an IEC conventional free‑air thermal current of 250 A and screw‑on plate mounting, it integrates cleanly into panel layouts. Fully compliant with IEC/EN 60947‑1 and 60947‑3, it provides reliable multi‑pole switching where clear, safe isolation is required across industrial and commercial installations.

Designed for performance headroom, it offers Ui 1000 V and Uimp 8 kV, with AC23A operational currents of 160 A at 400 V, 125 A at 500 V and 80 A at 690 V. Rated operational power reaches 90 kW at 400 V and 75 kW at 690 V. IP20 frontal protection, 30,000 mechanical cycles, and operation from −25 to 55 °C up to 3000 m underline robust service.
