GAZM040ET8 - 4P 40A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM040ET8?

Lovato GAZM040ET8 is a four‑pole I‑0‑II line changeover switch supplied in a rugged IEC/EN IP65 metal enclosure for reliable source selection. Rated Ith 40 A with AC operation, it offers Ui 1000 V and Uimp 8 kV performance. Compact enclosure dimensions of 150x200x120 mm suit control panels where space is at a premium.

Delivering AC21A and AC22A currents of 40 A up to 690 V, and AC23A 40 A at 400 V (25 A at 500/690 V), it handles 18.5 kW at 400 V and 22 kW at 690 V. With 10 kA conditional short‑circuit (gG40 fuse), 100,000‑cycle life, 1.8–2 Nm terminal torque and 0.75–16 mm² conductors, installation is robust and dependable.
