GAZM040T4 - 4P 40A METAL ENCLOSED ISOLATOR

Why Choose the GAZM040T4?

Lovato’s GAZM040T4 switch disconnector delivers reliable isolation in a robust IP65 metal enclosure. This four‑pole, 40 A AC device features a rotating red/yellow handle for clear status indication and safe operation. Compact 150×200×120 mm dimensions make it suitable for space‑constrained installations, providing dependable load switching and isolation across demanding industrial environments.

Engineered for performance, it carries Ui 1000 V and Uimp 8 kV, with AC21A/AC22A ratings to 40 A and AC23A up to 40 A (25 A at 500–690 V). Rated operational power reaches 18.5 kW at 400 V and 22 kW at 690 V. IP65 protection, 10 kA conditional short‑circuit (gG40 fuse), and IEC/EN 60947 compliance ensure durability, backed by 100,000 mechanical and electrical cycles.
