Single Phase Current Monitor
The Model 273 Single Phase Current Monitor provides essential oversight for industrial applications. It accurately detects over or under current conditions within selectable ranges of 0.5 to 5 amps or 2 to 10 amps, safeguarding connected equipment from potential damage. With automatic reset functionality, operational continuity is maintained without manual intervention, enhancing system uptime. The unit operates reliably across a supply voltage of 24VAC or 120VAC and maintains consistent performance within an operating temperature range of -20° to +131° F. Its robust design includes SPDT output contacts rated for 10A at 240VAC resistive, ensuring dependable switching capabilities. A mechanical relay life of 10 million operations and an electrical life of 100,000 at rated load underscore its durability. This monitor is a practical solution for maintaining system integrity and optimizing operational efficiency.
