3-Phase Monitor with Trip & Restart Delays
The 18-380-50 3-Phase Monitor provides essential protection for industrial systems. This unit detects critical conditions such as phase loss, low voltage, and phase reversal, safeguarding connected equipment. Featuring an automatic reset function, it ensures operational continuity without manual intervention. Users can configure trip delays from 1 to 30 seconds and restart delays from 1 to 300 seconds, allowing for precise system integration and recovery protocols. Its robust design includes SPDT 10 amp output contacts at 240VAC resistive, suitable for demanding applications. The monitor operates across a wide temperature range, ensuring reliability in diverse industrial environments. UL Recognition further confirms its adherence to established safety standards.
