GA080A - 3P SWITCH 80A-DIRECT/DOOR COUPLING

Why Choose the GA080A?

Designed for reliable isolation and load switching, the Lovato GA080A three-pole switch disconnector delivers 80 A performance for AC circuits. This direct operating version (SKU GA080A) combines robust build with ease of installation on a plate or 35mm DIN rail. With Ui 1000 V and Uimp 8 kV, it supports demanding industrial panels requiring safe disconnection and clear compliance with international standards.

Engineered for longevity with 30,000-cycle mechanical and electrical life (AC21A), the GA080A offers AC21A/AC22A/AC23A switching up to 690 V, including 80 A AC23A at 400 V and 45 kW rated operational power. IP20 frontal protection, -25 to +55 °C operation, and 4–70 mm² terminals (5–6 Nm) simplify panel integration. Conditional short-circuit current is 50 kA with gG80 fuse. Conforms to IEC/EN 60947-3/-1, UL98, CSA.
