GAZ125T4B - 4P SWITCH 125A-ENCLOS-BLACK HAND.PADLOCK

Why Choose the GAZ125T4B?

Lovato’s GAZ125T4B is a robust 4‑pole switch disconnector supplied in an enclosed, non‑metallic IP65 housing with a rotating black handle. Rated 125 A Ith for AC applications, it provides reliable on‑load isolation for machinery and panels. Compact yet spacious, the enclosure measures 220×280×170 mm (8.7×11×6.7''), helping simplify installation and ensure dependable operator control.

Engineered for demanding duties, it maintains AC21A and AC22A currents of 125 A up to 690 V, and AC23A ratings of 125 A at 400 V, 100 A at 500 V, and 47 A at 690 V. With Ui 1000 V, Uimp 8 kV and conditional short‑circuit current 50 kA (gG125 fuse), it meets IEC/EN 60947‑3 and 60947‑1 with 30,000 mechanical and electrical cycles.
