GAZ025ET8 - 4P CHANGEOVER SWITCH 25A ENCLOSED

Why Choose the GAZ025ET8?

Lovato GAZ025ET8 is a four-pole line changeover switch with I-0-II operation, designed for dependable source transfer in demanding installations. Rated 25 A and housed in a UL/CSA Type 4/4X non‑metallic enclosure with IP65 protection, it fits compactly at 175x210x149mm. With AC operation and robust insulation to 1000 V, it delivers safe, clear switching for panels where reliability and footprint both matter.

It sustains 25 A across AC21A, AC22A and AC23A duties up to 690 V, with 250 A making and 200 A breaking capacity at AC23A 400 V. Built for longevity with 100000 mechanical and electrical life cycles, it accepts 0.75–16 mm² conductors at 1.8–2 Nm. Operating from −25 to +55 °C up to 3000 m, it complies with IEC/EN 60947-3/-1 and UL 508/CSA C22.2 n°14.
