Lovato’s GX1668O48 is a rotary cam voltmeter switch from the GX series, engineered for phase‑neutral voltage selection. Supplied with an O48 modular service cover for 35 mm DIN rail mounting, a black handle and a 45 x 54 mm front plate, it integrates cleanly in control panels. As part of the Voltmeters and ammeters category, SKU GX1668O48 streamlines safe, reliable measurement switching.
With a 16 A conventional free air thermal current (Ith) and IP65 frontal sealing, this switch withstands demanding environments. Rated 6 kV impulse withstand and an operating range of −25 to +55 °C support robust installations. The GX square‑shaped contact block ensures dependable operation, while compliance with IEC/EN/BS 60947‑1/‑3/‑5‑1, IEC/EN/BS 61058‑1, UL60947‑4‑1 and CSA C22.2 n° 14 underpins panel‑building standards.
