GA040C - 3P SWITCH 40A-DOOR MOUNTING

Why Choose the GA040C?

Designed for reliable isolation in industrial panels, the Lovato GA040C three‑pole switch disconnector delivers 40 A AC performance in a door‑mount format. With a rated insulation voltage Ui of 1000 V and 8 kV impulse withstand, the GA040C supports AC21A and AC22A duties up to 690 V, and AC23A operation including 40 A at 400 V, with an IP20 frontal protection degree.

Built for endurance, it offers 100,000 mechanical cycles and 100,000 AC21A electrical cycles, plus 10 kA conditional short‑circuit current with gG40 fuse protection. A wide −25 to 55 °C operating range, 0.75–16 mm² conductor capacity and 1.8–2 Nm terminal torque aid dependable installation. Conforms to IEC/EN 60947‑3 and 60947‑1, with UL and CSA conformity as stated.
