Intermatic UWZ48-120U Terminals

The Intermatic UWZ48-120U is a high-precision, non-resettable 120V AC hour meter engineered for the rigorous runtime tracking demands of industrial motors, HVAC systems, and commercial control panels. Designed with a synchronous motor drive, this surface mount hour meter provides an accurate 7-digit readout (99,999.99 hours) with high-visibility 0.16-inch high numerals. The unit features white-on-black characters for full hours and yellow-on-black for tenths and hundredths, supplemented by an orange running indicator dial for immediate operational verification. This analog hour meter is built in a compact 48mm x 48mm bezel frame, making it a drop-in replacement for standard DIN-sized cutouts or surface installations. Utilizing simplified screw terminal wiring, the UWZ48-120U eliminates the need for separate terminal protection in indoor environments. With an IP20 environmental rating and a wide operating temperature range of -40°F to 160°F, this Intermatic hour meter ensures long-term reliability for critical preventive maintenance scheduling in demanding mechanical rooms.

• Precise Runtime Tracking: Records up to 99,999.99 hours with a highly accurate synchronous mechanical movement to ensure reliable maintenance intervals.
• Contractor-Grade Durability: Features an IP20-rated plastic housing designed for stable operation in ambient temperatures ranging from -40°F to 160°F.
• Simplified Field Installation: The inclusive plug-in base and screw terminal connections allow for rapid surface mounting and wiring without specialized tools.
• At-a-Glance Monitoring: High-contrast 7-digit display and an integrated orange dial provide immediate confirmation of system operation.
• Low Power Consumption: Efficient 1 VA power draw minimizes the electrical load on control circuits and monitoring systems.

Can the Intermatic UWZ48-120U be reset after a maintenance cycle?
No, this model is a non-resettable hour meter. This feature is intentional for industrial compliance and asset tracking to prevent tampering or accidental loss of total operation data.

Is this hour meter compatible with 50 Hz power systems?
The UWZ48-120U is specifically optimized for 120 VAC at 60 Hz frequencies. Using this unit on a 50 Hz system will result in inaccurate timing and potential mechanical wear.

What is the purpose of the orange dial on the display?
The orange dial serves as a running indicator. It rotates while the meter is receiving power and actively counting, allowing technicians to verify the unit is functional even before the decimal digits advance.
