GA063A - 3P SWITCH 63A-DIRECT/DOOR COUPLING

Why Choose the GA063A?

The Lovato GA063A is a three‑pole switch disconnector engineered for dependable AC isolation in panels and machinery. With 63 A Ith and direct operation, GA063A enables confident on‑load switching for AC21, AC22 and AC23 duties. Rated Ui 1000 V with 8 kV impulse withstand, it installs on 35 mm DIN rail or screws to a mounting plate, supporting fast, flexible integration in industrial control systems.

Built for longevity and compliance, this GA series isolator meets IEC/EN 60947‑3, IEC/EN 60947‑1, UL98 and CSA C22.2 n°4. It offers IP20 frontal protection, mechanical and AC21A electrical life of 30,000 cycles, and a conditional short‑circuit rating of 50 kA with gG63 fusing. Wide -25 to +55 °C operating range, 4–70 mm² conductors and 5–6 Nm terminals simplify robust, code‑aligned installations.
