Features
1. Compact to save panel space
The 24 × 48 mm hour meters are just half the DIN 48 × 48 stan-
dard size. They help save the panel space.
UL File No.: E42876
CSA File No.: LR39291
2. Reset button
The hour meters can be reset to zero (TH64 series).
3. Wide-ranging measurement display
The measurement can be displayed from 0.1 hour up to
99999.9 hours (TH63 series). The dial size is the same as that
of 48 × 48 DIN size hour meters (TH14 and TH24 series).
4. Easy to install
The flat terminals (#187) are used for easier wiring. There is no
need to undo the lock spring.
5. High-performance sync motor with 50/60 Hz selector
The noise-resistant, accurately turning motor is employed to
provide for longer period of measurement. The power frequency
can be selected for 50 or 60 Hz.
6. Rotary indicator
The rotary indicator makes one turn every 72 seconds for moni-
toring.
7. Compliant with UL, CSA and CE.
Typical applications
Management of small generators and food processing
machines; hour counting for leased equipment; maintenance
management of various equipment, etc.
