GAZS100 - S/STEEL ENCLOSED ISOLATOR SWITCH 100A 3 POLE

Why Choose the GAZS100?

Lovato GAZS100 is a three-pole switch disconnector housed in an IP65 AISI 304 stainless steel enclosure for reliable isolation in demanding environments. The GAZS100 features a rotating red/yellow handle and a 100 A IEC conventional free air thermal current (Ith) for AC systems. Compact enclosure dimensions of 150x200x120 mm (5.9x7.9x4.7'') support enclosed installation in control panels and machinery.

Designed for performance, it offers Ui 1000 V and Uimp 8 kV, with AC21A/AC22A ratings at 100 A up to 690 V and AC23A ratings of 100 A (400 V), 80 A (500 V) and 47 A (690 V). Conditional short-circuit current is 50 kA with gG100 fuse. Mechanical and electrical life reach 30,000 cycles, with operation from -25 to +55 °C up to 3000 m. Compliant with IEC/EN 60947-3 and 60947-1.
