GAZ125B - 3P SWITCH 125A-ENCLOS-BLACK HAND.PADLOCK

Why Choose the GAZ125B?

Lovato’s GAZ125B is an enclosed switch disconnector designed for dependable on‑load isolation. This three‑pole, 125 A unit is housed in a robust IP65 non‑metallic enclosure with a rotating black handle for clear, positive operation. Compact yet spacious at 220×280×170 mm (8.7×11×6.7''), the GAZ125B suits industrial panels and machinery isolation points where safe manual switching and environmental protection are essential.

Engineered for resilience, it offers Ui 1000 V and Uimp 8 kV, with AC21A/AC22A operational currents of 125 A up to 690 V. AC23A duty is 125 A at 400 V, 100 A at 500 V, and 47 A at 690 V. With 50 kA conditional short‑circuit current (gG125 fuse), 30,000-cycle mechanical and electrical life, −25 to +55 °C operation, and IEC/EN 60947-3 conformity, it’s built for demanding sites.
