Over & Under 3-Phase Monitor
The MODEL 269R Over & Under 3-Phase Monitor, SKU C269R, provides essential protection for industrial equipment. This device monitors high voltage, low voltage, phase loss, and phase reversal conditions, ensuring operational integrity. With a nominal AC voltage of 480VAC, its adjustable ranges (upper 400-540V, lower 380-460V) allow for precise application matching. Its fixed response time of 4 ±2 seconds and automatic reset feature minimize downtime by quickly addressing power anomalies. The unit's SPDT 10A at 240VAC resistive output contacts offer reliable control for connected systems. Designed for surface mounting, it operates effectively across a -20° to +130° F temperature range and tolerates 0-97% humidity without condensation. This monitor contributes to system longevity by safeguarding against common power fluctuations and phase issues, maintaining consistent performance.
