GE0250ET4 - 4P CHANGEOVER SWITCH

Why Choose the GE0250ET4?

The Lovato GE0250ET4 four-pole changeover switch delivers dependable AC supply transfer and isolation for control panels and switchboards. With Ith 250 A, Ui 1000 V and Uimp 8 kV, it is built for robust performance. GE0250ET4 mounts by screw-on plate and provides IP20 frontal protection, with AC21A/AC22A/AC23A operating currents to suit a range of load switching duties.

Engineered to IEC/EN 60947-1 and 60947-3, this switch offers 100 kA conditional short-circuit performance with gG250 fuse protection and a mechanical life of 10,000 cycles. Rated operational power reaches 100 kW at 400 V AC23A, with per-pole dissipation 8.5 W. It supports -25 to 55 °C operation, up to 3000 m altitude, pollution degree 3, and 24 Nm maximum terminal tightening torque.
