GAZS063SA - S/STEEL ENCLOSED ISOLATOR SWITCH 63A 3 POLE

Why Choose the GAZS063SA?

Lovato’s GAZS063SA switch disconnector delivers reliable isolation in a rugged, enclosed design. Housed in an IP65 AISI 304 stainless steel enclosure with a rotating red/yellow handle, this 3‑pole unit is rated 63 A (Ith) for AC systems. With 1000 V rated insulation (Ui) and 8 kV impulse withstand (Uimp), it provides dependable performance for industrial control and maintenance isolation where durability and safety are paramount.

Operational ratings include Ie up to 63 A in AC21A at 400/500/690 V, 45 A in AC22A at 500/690 V, and 45/25 A in AC23A at 400/500/690 V, with 22 kW AC23A power at 400 V and 690 V. It offers a 10 kA conditional short-circuit current using gG63 fusing, 100000 mechanical cycles, and an operating range of -25 to +55 °C. Compact 150x200x120 mm dimensions and IEC/EN 60947-3 compliance make it ideal for dependable panel isolation.
