GA025A - 3P SWITCH 25A-DIRECT/DOOR COUPLING

Why Choose the GA025A?

The Lovato GA025A is a three‑pole switch disconnector for direct operation at 25 A, engineered for dependable isolation and load switching in industrial control panels. With Ui 1000 V and Uimp 8 kV, it provides strong dielectric performance. This GA series device mounts on a 35mm DIN rail or screws to a plate, offering IP20 frontal protection and Pollution Degree 3 suitability for demanding environments.

Rated 25 A across AC21A, AC22A and AC23A categories up to 690 V, the GA025A delivers 11 kW at 400 V and 22 kW at 690 V (AC23A). Conditional short‑circuit current is 10 kA with gG25 fuse protection. Terminals accept 0.75–16 mm² conductors at 1.8–2 Nm. Operating range is −25 to +55 °C, storage −40 to +70 °C, and altitude up to 3000 m.
