It measures from 0 to 400 VAC, so it covers standard single-phase and three-phase line voltages up to 400 V without an external PT — that's the main reason you'd reach for this over a general-purpose digital panel meter. The 24 VAC/DC supply means it plays nice with control transformers or a common 24 VDC panel bus, which simplifies wiring in mixed-supply cabinets. The IP66-rated front bezel is the key spec for panel builders: it seals against hose-down and dust ingress from the front, so this meter can live on a panel door in a washdown area — food, beverage, or chemical processing lines. The rectangular cutout is 92.00 mm x 45.00 mm, which is a standard 1/8 DIN footprint, so it drops into existing panel punches without rework. Screw terminals mean no special crimp tooling on the line — just strip, torque, and go. The dual-row LCD shows 5 characters per row with a large 0.560\" (14.20 mm) main display and a smaller 0.192\" (4.90 mm) secondary row. That second row is useful for displaying engineering units or a second process variable if you add an option card — the base unit supports option cards for output or communication, so you can expand it later without swapping the whole meter.","metaTitle":"K3HB-XVA 24VAC/VDC Process Meter, 0-400VAC, Panel Mount","metaDescription":"K3HB-XVA 24VAC/VDC process meter from the K3HB-X series.
