Features
1. Compact to save panel space The 24 × 48 mm hour meters are just half the DIN 48 × 48 standard 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 monitoring. 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.
