3-Phase Monitor with Adjustable Trip & Restart Delays

22H

The 22-H 3-Phase Monitor provides critical protection for industrial systems. Its adjustable trip delays, ranging from 1 to 30 seconds, allow for precise fault response customization, preventing unnecessary shutdowns. A wide 475-600 VAC operating voltage range and 50/60Hz frequency compatibility ensure broad application suitability across diverse electrical environments. The unit supports both Wye and Delta systems without requiring a neutral connection, simplifying installation and reducing wiring complexity. Adjustable restart delays, from 1 to 500 seconds, facilitate controlled equipment re-energization after a fault event, protecting machinery from immediate re-stress. With 2X SPDT 10A output contacts and an operating temperature range of -20° to +140° F, the 22-H maintains system integrity and operational continuity under demanding conditions. Its auto-reset functionality minimizes manual intervention, enhancing overall system uptime and reliability.
