GAZM160 - 3P 160A METAL ENCLOSED ISOLATOR

Why Choose the GAZM160?

Engineered for dependable isolation, the Lovato GAZM160 is a three-pole switch disconnector housed in a rugged IP65 metal enclosure with a red/yellow rotary handle. Rated Ith 160 A for AC applications, this enclosed unit simplifies installation and operator safety. Compact yet robust at 200x300x120 mm (7.9x11.8x4.7''), the GAZM160 suits space-constrained panels while providing clear, positive switching.

Backed by IEC/EN 60947-3 and 60947-1 compliance, it delivers strong electrical performance: Ui 1000 V, Uimp 8 kV and utilisation category ratings up to AC21A 160 A. A conditional short-circuit current of 50 kA (with gG160 fuse), 30,000 mechanical cycles and operation from -25 to +55 °C ensure long service life across demanding industrial environments.
