The Lovato GX1667U is a GX series rotary cam voltmeter switch engineered for accurate phase‑to‑phase voltage selection. As part of the Voltmeters and ammeters range, this unit features U mounting for front installation with a black handle and a compact 48 × 48 mm front plate. Switching diagram 67 designates dedicated phase‑phase voltmeter switching, while a conventional free‑air thermal current (Ith) of 16 A supports robust performance in industrial panels.
Built for reliability, the GX16 designation delivers a square‑shaped contact block within the GX series. The device offers IP65 frontal protection, a 6 kV rated impulse withstand voltage (Uimp), and dependable operation from −25 to +55 °C (storage −40 to +70 °C). It conforms to IEC/EN/BS 60947‑1, 60947‑3, 60947‑5‑1, IEC/EN/BS 61058‑1, UL60947‑4‑1 and CSA C22.2 n° 14, with a Sustainability certification.
