GAZS063 - S/STEEL ENCLOSED ISOLATOR SWITCH 63A 3 POLE

Why Choose the GAZS063?

The Lovato GAZS063 switch disconnector delivers reliable three-pole, 63 A isolation in a rugged, enclosed design. Housed in an IP65 stainless steel AISI 304 enclosure with a high-visibility red/yellow rotary handle, it's built for harsh industrial environments. Its compact 150x200x120 mm footprint simplifies installation where space is limited while maintaining robust performance for AC circuits and compliant operation to IEC/EN 60947-3.

With Ui 1000 V and 8 kV impulse withstand, the device supports on-load switching across AC21A, AC22A and AC23A duties up to 690 V. It offers 30,000 mechanical and AC21A electrical cycles, 50 kA conditional short-circuit rating with gG63 fuse, and works from -25 to +55 °C. Terminal torque is 5 to 6 Nm with 4 to 70 mm² conductors.
