GAZM025ET8 - 4P 25A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM025ET8?

The Lovato GAZM025ET8 is a four-pole line changeover switch (I-0-II) supplied in a robust IEC/EN IP65 metal enclosure for dependable source transfer. Rated at 25 A with AC operation, it offers Ui 1000 V and Uimp 8 kV performance. Compact enclosure dimensions of 150x200x120mm help simplify panel layouts while maintaining protection, making it a reliable choice for industrial switching and power continuity.

Consistent performance is assured with Ie 25 A across AC21A, AC22A and AC23A at 400, 500 and 690 V, plus operational power of 11 kW at 400 V and 22 kW at 690 V. Designed for durability, it delivers 100000 mechanical and electrical cycles, supports 0.75 to 16 mm² conductors at 1.8–2 Nm, and meets IEC/EN 60947-3 and 60947-1. Conditional short-circuit current is 10 kA with gG25 fuse protection.
