GA100A - 3P SWITCH 100A-DIRECT/DOOR COUPLING

Why Choose the GA100A?

Lovato GA100A is a three‑pole switch disconnector designed for safe AC isolation in industrial panels. This direct operating version delivers 100 A Ith with robust AC21A/AC22A/AC23A performance across common voltages. Rated to 1000 V Ui and 8 kV Uimp, the GA100A mounts on a 35 mm DIN rail or screws to a plate, and conforms to IEC/EN 60947‑3, IEC/EN 60947‑1, UL98 and CSA C22.2 n°4.

With AC23A ratings up to 100 A at 400 V and 55 kW, the GA100A handles demanding load switching; at 500 V it is 80 A, and 690 V 47 A. It offers 50 kA conditional short‑circuit current, IP20 frontal protection, and 30,000-cycle mechanical and electrical life. Terminals accept 4–70 mm² conductors, tightened to 5–6 Nm. Operating range −25 to +55 °C, up to 3000 m altitude.
