Model 19 3-Phase Monitor with Trip & Restart Delays
The Model 19 3-Phase Monitor (SKU 19-415-50) provides essential protection for 415VAC, 50Hz systems. It detects phase loss, low voltage, and phase reversal, ensuring operational integrity. Users can configure trip delays from 1 to 30 seconds and restart delays from 1 to 300 seconds, allowing precise system response tailoring. This monitor features automatic reset functionality and robust transient protection up to 2500VAC for 10ms. Its repeat accuracy of ± 0.1% of set point ensures consistent performance. With SPDT 10 amp output contacts and compatibility with both Wye and Delta systems without requiring a neutral connection, the Model 19 offers versatile and reliable three-phase monitoring. Its durable construction, wide operating temperature range from -20° to +131° F, and 0-97% humidity tolerance support demanding industrial environments, minimizing downtime and extending equipment life.
