Over & Under 3-Phase Monitor
The Model 269 Over & Under 3-Phase Monitor provides comprehensive protection for industrial equipment operating on 208/240VAC systems. It safeguards against high voltage, low voltage, phase loss, and phase reversal, ensuring operational continuity and preventing costly damage. An adjustable response time, from 1 to 10 seconds, allows for precise system integration tailored to specific application requirements. A 5-year unconditional warranty ensures long-term reliability and reduced maintenance. The unit's automatic reset function and robust transient protection of 2500VRMS for 10ms minimize downtime and enhance system resilience. Operating effectively across a wide temperature range of -20° to +130° F, it maintains consistent performance in diverse industrial environments. UL Listed and CSA Certified, the B269 meets recognized safety and performance standards, providing assurance for critical applications. Its SPDT 10A output contacts facilitate versatile control applications.
