GAZM040 - 3P 40A METAL ENCLOSED ISOLATOR

Why Choose the GAZM040?

Lovato GAZM040 is an enclosed switch disconnector for reliable three-phase isolation. In a robust IP65 metal enclosure with a rotating red/yellow handle, this 3-pole, 40 A unit is engineered for AC duties where safe, visible switching matters. The compact housing measures 150x200x120 mm (5.9x7.9x4.7"), combining durability with clear operator control for machinery, panels and plant areas.

Performance is proven with Ui 1000 V and Uimp 8 kV, plus 40 A Ie for AC21A/AC22A up to 690 V. For AC23A, it delivers 40 A at 400 V and 25 A at 500/690 V, with 18.5 kW at 400 V and 22 kW at 690 V. Conditional short-circuit current is 10 kA with gG40 protection. Built for endurance to 100,000 mechanical and electrical cycles, it operates from -25 to +55 °C and complies with IEC/EN 60947-3 and 60947-1.
