3-Phase Monitor
The Model 2642 3-Phase Monitor provides essential protection for industrial systems. It continuously monitors for phase loss, low voltage, and phase reversal, safeguarding critical equipment from operational damage. With an adjustable trip delay and a response time configurable from 0.2 to 10 seconds, this monitor offers precise control over system response. Its robust design accommodates an operating temperature range of -20° to +131° F and features DPDT output contacts rated at 10 amps for 240VAC resistive loads. The option for automatic or manual reset enhances operational flexibility, ensuring consistent performance and minimizing downtime in diverse industrial applications. This device is engineered for reliability, featuring a repeat accuracy of ±0.5% of setpoint and a transient protection of 2500 VRMS for 10ms. Its 380VAC nominal voltage and 50Hz frequency compatibility make it suitable for specific industrial power requirements. The unit's compact form factor and surface mounting capability simplify installation.
