GAZ025ET6 - 3P CHANGEOVER SWITCH 25A ENCLOSED

Why Choose the GAZ025ET6?

The Lovato GAZ025ET6 is a three‑pole line changeover switch with I‑0‑II positions, housed in a robust non‑metallic enclosure. Rated at 25 A with AC operation, it offers IP65 protection and UL/CSA Type 4/4X suitability. With a rated insulation voltage of 1000 V and 8 kV impulse withstand, it delivers dependable manual transfer in demanding industrial and commercial installations.

Performance is consistent across duty categories: AC21A, AC22A and AC23A currents are 25 A up to 690 V, with operational power to 11 kW at 400 V and 22 kW at 690 V. It withstands 10 kA conditional short‑circuit current with gG25 fusing, and offers 100,000 mechanical and electrical cycles. Terminals accept 0.75–16 mm² conductors with 1.8–2 Nm torque.
