GA040A - 3P SWITCH 40A-DIRECT/DOOR COUPLING

Why Choose the GA040A?

Lovato’s GA040A is a three‑pole switch disconnector designed for reliable isolation in AC systems. This direct‑operated, 40 A device delivers robust performance with a 1000 V rated insulation voltage and 8 kV impulse withstand. The compact unit mounts by screw on plate or on a 35 mm DIN rail, offering flexible installation. SKU GA040A meets IEC/EN 60947-3 and 60947-1, plus UL60947-4-1 and CSA C22.2 standards.

Rated for AC21A, AC22A and AC23A duties, the GA040A carries 40 A at 400–690 V in AC21/22, and in AC23A delivers 40 A at 400 V and 25 A at 500–690 V. It offers 18.5 kW (400 V) and 22 kW (690 V) operational power, IP20 frontal protection and 10 kA conditional short‑circuit current with gG40 fuse. With 100,000 mechanical/electrical cycles, −25 to 55 °C operation and pollution degree 3, it’s built for dependable service.
