GAZM125T4 - 4P 125A METAL ENCLOSED ISOLATOR

Why Choose the GAZM125T4?

Lovato’s GAZM125T4 switch disconnector provides reliable isolation in an IP65 metallic enclosure. This four-pole unit includes a rotating red/yellow handle for clear status indication and safe operation. With an Ith of 125 A for AC systems, it suits industrial panels and machinery requiring dependable disconnection. The enclosure measures 200 x 300 x 120 mm (7.9 x 11.8 x 4.7 in) to support straightforward wiring and installation.

Performance is proven with Ui 1000 V, Uimp 8 kV and AC23A ratings up to 125 A at 400 V, 100 A at 500 V and 47 A at 690 V. Conditional short-circuit current is 50 kA when protected by a gG125 fuse. Built for longevity with 30,000 mechanical and electrical operations, it accepts 4 to 70 mm² conductors, torque 5 to 6 Nm, and operates from -25 to +55 °C up to 3000 m altitude.
