GAZM100T4 - 4P 100A METAL ENCLOSED ISOLATOR

Why Choose the GAZM100T4?

Lovato GAZM100T4 is a four-pole switch disconnector supplied in an IEC/EN type IP65 metal enclosure with a rotating red/yellow handle. Rated Ith 100 A for AC systems, it delivers dependable isolation with Ui 1000 V and Uimp 8 kV. Compact yet robust at 150x200x120 mm (5.9x7.9x4.7''), this enclosed unit streamlines specification and installation for industrial panels, machinery circuits and local isolation points.

Engineered for demanding duties, the GAZM range offers AC21A and AC22A operation at 100 A up to 690 V, plus AC23A ratings of 100 A (400 V), 80 A (500 V) and 47 A (690 V). With a conditional short-circuit current of 50 kA using gG100 fusing, IP65 sealing, and 30,000-cycle mechanical and electrical life (AC21A), it ensures reliable service across -25 to +55 °C and up to 3000 m altitude.
