GAZS040 - S/STEEL ENCLOSED ISOLATOR SWITCH 40A 3 POLE

Why Choose the GAZS040?

Engineered by Lovato, the GAZS040 is a three-pole switch disconnector supplied in an IP65 AISI 304 stainless steel enclosure with a rotating red/yellow handle. Rated at 40 A Ith for dependable isolation, this compact unit measures 150x200x120 mm (5.9x7.9x4.7''). SKU GAZS040 suits AC applications demanding durable, safe, and straightforward operation.

Designed for reliability, it offers Ui 1000 V and Uimp 8 kV, with AC21A and AC22A ratings of 40 A up to 690 V. For AC23A duty it provides 40 A at 400 V and 25 A at 500/690 V, with mechanical and AC21A electrical life of 100,000 cycles. IP65 sealing and AISI 304 construction aid durability in demanding industrial settings.
