GAZ125ET6 - 3P CHANGEOVER SWITCH 125A ENCLOSED

Why Choose the GAZ125ET6?

Lovato GAZ125ET6 is a three-pole line changeover switch I-0-II supplied in a UL/CSA Type 4/4X non-metallic enclosure for dependable source selection. Rated 125 A with IP65 frontal protection, this compact assembly measures 280 x 220 x 172 mm. With Ui 1000 V and Uimp 8 kV, GAZ125ET6 delivers robust performance for AC applications requiring secure changeover and clear switching positions.

Designed to IEC/EN 60947-3, IEC/EN 60947-1 and UL98 and CSA C22.2 n°4, it offers AC21A and AC22A currents up to 125 A at 690 V, and AC23A performance of 125 A at 400 V. Rated operational power reaches 55 kW at 400 V. With 50 kA conditional short-circuit current (gG125 fuse), 30,000 mechanical/electrical cycles, -25 to +55 °C operation and 4–70 mm² conductors, installation is straightforward.
