GAZM040ET6 - 3P 40A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM040ET6?

Designed for dependable source transfer, the Lovato GAZM040ET6 is a three-pole line changeover switch with I-0-II positions housed in a robust IP65 metal enclosure. Rated Ith 40 A with AC operation, it offers strong insulation (Ui 1000 V) and impulse withstand (Uimp 8 kV). Compact 150x200x120 mm dimensions support easy installation while meeting IEC/EN 60947-3 and 60947-1 requirements.

Engineered for demanding duty, it delivers 40 A across AC21A and AC22A up to 690 V, and AC23A performance of 40 A at 400 V or 25 A at 500/690 V. High endurance is assured with 100,000 mechanical and AC21A electrical cycles, plus 400 A making and 320 A breaking at 400 V. Operates from -25 to +55 °C at altitudes to 3000 m.
