Switchboards and generator panels often have a single analog voltmeter that needs to read all three phase-to-phase voltages. The Lovato GX1667U is a front-mount rotary cam voltmeter switch (scheme 67) with two contact wafers that selects L1-L2, L2-L3 and L3-L1. Panel builders fit it beside the meter on a 48 x 48 mm plate for a clean, compact door layout.
Why panel builders pick it
- Selects all three phase-to-phase voltages to one voltmeter.
- Compact 48 x 48 mm front plate with black handle.
- IP65 front protection once installed; IP20 terminals.
- cULus listed; 600 V UL/CSA insulation rating.
- Rated for 1 million mechanical operations.

Pro tip from the counter
Check the system voltage before specifying it: Lovato lists a 440 VAC rated operational voltage, so on 575/600 V Canadian services have the panel designer confirm suitability with Lovato or measure through potential transformers. Fuse the voltage taps ahead of the switch so a wiring fault in the door does not trip the main.
Best for: switchboard and distribution panel metering, generator control panels, industrial control panel builders, 3-phase voltage checks
