Designed for the GA...A series, the Lovato GAX42063SA fourth pole add-on accessory ensures simultaneous closing with the main switch poles for dependable isolation and switching. Rated Ith 63 A with AC operation and one pole, it extends GA063SA assemblies to a fourth pole while aligning with IEC/EN 60947 requirements for industrial control panels and power distribution boards.
Built for demanding environments, it offers Ui 1000 V and Uimp 8 kV, with Ie ratings up to 63 A in AC21A/AC22A and 25 A in AC23A at 500–690 V. Making/breaking capacity at AC23A 400 V is 450/360 A. Durable by design, it delivers 100,000 mechanical cycles and 15,000 electrical (AC21A). Installation supports 0.75–16 mm² conductors, 1.8–2 Nm torque, operation from -25 to +55 °C, up to 3000 m, pollution degree 3.
