GA063C - 3P SWITCH 63A-DOOR MOUNTING

Why Choose the GA063C?

Lovato’s GA063C three‑pole switch disconnector provides dependable AC isolation for control panels and machinery. The door‑mount version delivers 63 A Ith, Ui 1000 V and 8 kV Uimp, with IEC/EN 60947‑3 and UL98 compliance. SKU GA063C offers IP20 frontal protection, 30,000‑cycle mechanical and AC21A electrical life, plus AC‑23A 400 V making 1250 A and breaking 1000 A.

Rated for AC‑21A/‑22A/‑23A duties, it carries 63 A at 400–500 V and 47 A at 690 V where specified. Conditional short‑circuit current is 50 kA with gG63 fuse. Terminals accept 4–70 mm² conductors and tighten to 5–6 Nm. Operates from −25 to +55 °C up to 3000 m altitude, Pollution Degree 3, with low 1.6 W max power loss per pole.
