GAZM125 - 3P 125A METAL ENCLOSED ISOLATOR

Why Choose the GAZM125?

Lovato’s GAZM125 switch disconnector delivers robust isolation in a compact, enclosed IP65 metal housing. This three-pole, 125 A AC unit features a rotating red/yellow handle for clear on/off status and safe operation. Sized 200 x 300 x 120 mm, it suits space-constrained panels while maintaining durability. Built to IEC/EN 60947 standards, it offers reliable performance for industrial switching and maintenance lock-off.

Engineered for demanding environments, it achieves Ui 1000 V and Uimp 8 kV, with AC21A and AC22A currents up to 125 A at 690 V. For AC23A duties it delivers 125 A at 400 V, 100 A at 500 V and 47 A at 690 V. With 30,000-cycle mechanical and electrical life, 6.3 W max power dissipation per pole, and terminals accepting 4–70 mm² conductors at 5–6 Nm, installation is straightforward.
