GA063SA - 3P SWITCH 63A-DIRECT/DOOR COUPLING

Why Choose the GA063SA?

Lovato’s GA063SA is a three-pole switch disconnector designed for reliable AC isolation in control panels and machinery. With Ith 63 A and Ui 1000 V, it delivers dependable performance across AC21A, AC22A and AC23A duties. The direct operating version mounts on a plate or 35 mm DIN rail for flexible installation. SKU GA063SA meets IEC/EN 60947 standards with UL and CSA recognition.

Designed for safety and longevity, the GA063SA offers IP20 frontal protection, mechanical life of 100,000 cycles and electrical life up to 15,000 cycles (AC21A). Rated Uimp 8 kV and conditional short-circuit current 10 kA with gG63 fuse, it withstands demanding environments. Terminals accept 0.75–16 mm² conductors with 1.8–2 Nm torque. Operating temperature −25 to +55 °C and installation up to 3000 m, pollution degree 3.
