Lovato GX1667O48 is a GX series rotary cam voltmeter switch for selecting phase-phase voltages in industrial control panels. Part of the Voltmeters and ammeters category, it includes the O48 modular service cover for 35 mm DIN rail mounting with a black handle, plus a compact 45 x 54 mm front plate. SKU GX1667O48 delivers dependable measurement switching.
With a 16 A IEC conventional free air thermal current (Ith) and 6 kV rated impulse withstand voltage (Uimp), the GX16 designation offers robust performance. The frontal IP65 rating suits demanding environments, with an operating temperature from -25 to +55 °C. Built on the GX square-shaped contact block, it conforms to IEC/EN/BS and UL/CSA standards for assured compatibility.
