GAZ063SAET8 - 4P CHANGEOVER SWITCH 63A ENCLOSED

Why Choose the GAZ063SAET8?

Engineered by Lovato, the GAZ063SAET8 is a four‑pole I‑0‑II line changeover switch in a UL/CSA Type 4/4X non‑metallic enclosure rated 63 A. With compact 175x210x149mm dimensions and IP65 frontal protection, it suits demanding environments. Rated insulation voltage Ui 1000 V and impulse withstand Uimp 8 kV ensure robust performance for supply switching across AC networks.

Certified to IEC/EN 60947-3, IEC/EN 60947-1 and UL 508/CSA, it offers Ie 63 A AC21A at 400–690 V, AC22A 63 A at 400 V and 45 A at 500–690 V, and AC23A 45 A at 400 V and 25 A at 500–690 V. Rated 22 kW AC23A at 400/690 V, with 10 kA conditional short‑circuit (gG63 fuse). Mechanical life 100000 cycles and IP65 simplify dependable installation.
