GAZM063T4 - 4P 63A METAL ENCLOSED ISOLATOR

Why Choose the GAZM063T4?

The Lovato GAZM063T4 is a four‑pole switch disconnector in a robust IP65 metal enclosure, engineered for reliable isolation in industrial and commercial installations. Featuring a front‑mounted red/yellow rotary handle and rated at 63 A, it offers clear, safe operation for maintenance and emergency cut‑off. Compact yet spacious, the 150x200x120mm housing simplifies mounting while protecting against dust and water jets.

Built for demanding duties, it carries Ui 1000 V and Uimp 8 kV, with AC21A/AC22A 63 A ratings up to 690 V and AC23A 63 A (400/500 V) or 47 A (690 V). A 50 kA conditional short‑circuit rating with gG63 fuse, 30,000 mechanical and electrical cycles, and 4–70 mm² terminals (5–6 Nm) ensure durability. Operates from -25 to +55 °C, to 3000 m, conforming to IEC/EN 60947-3 and 60947-1.
