GE0251 - 3P SWITCH DISCONNECTOR

Why Choose the GE0251?

Engineered for reliable isolation and switching, the Lovato GE0251 three-pole switch disconnector delivers 250 A AC performance for demanding industrial panels. With SKU GE0251, this unit mounts via screw-on plate, provides IP20 frontal protection, and is designed to IEC/EN 60947-1 and 60947-3. A 1000 V rated insulation voltage and 8 kV impulse withstand ensure robust dielectric strength across varied installations.

High utilisation categories are supported, with Ie up to 250 A in AC21A and AC22A at 400-500 V, and up to 250/200/160 A across AC23A duty at 400/500/690 V. Rated operational power reaches 138 kW at 400 V and 153 kW at 690 V. Low 2.5 W per-pole dissipation, 20,000 mechanical cycles, and operation from -25 to 55 °C enhance uptime.
