The Lovato GX1668U rotary cam voltmeter switch delivers reliable phase-neutral voltage selection in compact panels. Part of the GX series square contact block family, this unit suits voltmeters and ammeters applications where clear, front-operated control is essential. Designed for front mounting with a black handle and a 48x48mm front plate, it integrates neatly into control panels and switchboards without sacrificing accessibility.
Engineered for demanding environments, the GX1668U provides a 16A Ith rating, IP65 frontal protection, and robust electrical endurance with a 6kV rated impulse withstand voltage. Operating temperatures from -25 to +55 °C and compliance with IEC/EN/BS 60947 standards make it a dependable choice for industrial measurement and monitoring. The GX square-shaped contact block ensures consistent performance and straightforward panel integration.
