GAZ125T4 - 4P SWITCH 125A-ENCLOS-R/Y HAND.PADLOCK

Why Choose the GAZ125T4?

Lovato GAZ125T4 is a four‑pole switch disconnector in a robust IP65 non‑metallic enclosure, engineered for reliable isolation in AC systems. Delivering 125 A Ith with a rotating red/yellow handle, it suits enclosed installations where clear, safe disconnection is required. Rated Ui 1000 V and Uimp 8 kV, this GAZ series unit combines strong performance with compact 220×280×170 mm dimensions for easy placement.

Tested to IEC/EN 60947-3 and 60947-1, the GAZ125T4 achieves AC21A and AC22A currents of 125 A up to 690 V, with AC23A ratings of 125 A at 400 V, 100 A at 500 V and 47 A at 690 V. With 50 kA conditional short‑circuit rating (gG125 fuse), 30,000 mechanical and electrical cycles, and 4–70 mm² terminals tightened to 5–6 Nm, it delivers dependable service.
