Intermatic UWZ48E-24U Hour Meter

The Intermatic UWZ48E-24U is an electromechanical hour meter designed for industrial electrical control and automation applications. It operates on 24V AC power at 50/60 Hz and tracks elapsed time up to 99,999.99 hours with a seven-digit display showing hours and hundredths.

Square plastic flush-mount bezel

The meter features a square plastic bezel measuring 1.88 in by 1.88 in for flush mounting into panels or enclosures. A key reset mechanism prevents accidental clearing of the recorded time. The unit carries a NEMA 1 rating and functions across an ambient temperature range of -40 to 160 degrees Fahrenheit.

Replaces meters lacking key reset

This model suits installations that require a tamper-resistant key reset rather than a simple push-button. It upgrades older counters limited to lower maximum readings or narrower temperature ranges. The jump is worthwhile when a durable plastic housing and 24V AC compatibility match the existing control circuit.

Questions about this item

What does the 24 V AC 50/60 Hz rating mean for wiring this hour meter?

It requires a 24 V AC supply at either 50 Hz or 60 Hz; the meter counts elapsed time only when that voltage is present across its terminals.

What panel cut-out and depth clearance does the 1.88 in square flush-mount bezel need?

Cut a 1.88 in × 1.88 in square hole; behind the panel allow at least 1.65 in total depth (1.3 in bezel-to-back plus the body).

How is the electromechanical counter installed and what wiring mistake should be avoided?

Mount the meter in the square cut-out, secure the flush bezel, then connect the two leads to a 24 V AC source — do not apply DC voltage or the counter will not advance.
