Model 19 3-Phase Monitor with Trip & Restart Delays
The Model 19 3-Phase Monitor offers essential protection for industrial systems. This device detects critical anomalies including phase loss, low voltage, and phase reversal, ensuring operational integrity. Its adjustable trip and restart delays, ranging from 1-30 seconds and 1-300 seconds respectively, allow for precise system integration and controlled recovery. The automatic reset feature minimizes downtime. Compatible with both Wye and Delta systems, it does not require a neutral connection, simplifying installation. With a five-year unconditional warranty, this monitor provides reliable performance and long-term value, safeguarding equipment against electrical irregularities. Its robust design ensures consistent operation in demanding environments, tolerating 0-97% humidity without condensation and operating from -20° to +131° F. Power consumption is a low 2.4W.
