GAZ063SAET6 - 3P CHANGEOVER SWITCH 63A ENCLOSED

Why Choose the GAZ063SAET6?

Lovato’s GAZ063SAET6 is a three-pole line changeover switch with I-0-II positions, housed in a UL/CSA Type 4/4X non-metallic enclosure. Rated 63 A with Ui 1000 V and Uimp 8 kV, it offers IP65 protection. Compact dimensions 175x210x149 mm (6.9x8.3x5.9'') suit control panels where space and reliability matter.

Designed for dependable source transfer, it delivers AC21A currents up to 63 A and AC23A 45 A at 400 V, with 22 kW operational power. A 10 kA conditional short-circuit rating with gG63 fuse enhances protection. Durable construction provides 100,000 mechanical cycles and 15,000 electrical (AC21A). Terminals accept 0.75–16 mm² conductors, tightened to 1.8–2 Nm. Operates from -25 to +55 °C. Complies with IEC/EN 60947-3, IEC/EN 60947-1, UL 508 and CSA C22.2 No. 14.
