Why Choose the GX1666O48?

SKU GX1666O48 is Lovato’s GX series rotary cam voltmeter switch for phase‑neutral and phase‑phase voltages. Part of our voltmeters and ammeters range, it provides a 16 A conventional free air thermal current (Ith) and installs on 35 mm DIN rail via the O48 modular service cover with black handle. A compact 45 x 54 mm front plate ensures tidy panel integration and clear operator control.

Engineered for dependable service, the GX16 designation features the GX square‑shaped contact block and IP65 frontal protection. It withstands 6 kV impulse voltage (Uimp) and operates from −25 to +55 °C, with storage down to −40 °C and up to +70 °C. Designed to IEC/EN/BS 60947 and IEC/EN/BS 61058-1, plus UL and CSA references, it suits demanding industrial panels.
