Model 274 3-Phase Current Monitor
The Model 274 3-Phase Current Monitor provides essential oversight for industrial electrical systems. Operating at 240VAC, it monitors three simultaneous currents within a 1 to 5 amp range, ensuring precise control. This device supports a frequency range of 50 to 400Hz, accommodating diverse application requirements. Its SPDT 10A at 240VAC resistive contact rating ensures robust switching capabilities for connected loads. Users can configure reset options for automatic or manual operation, enhancing system flexibility and response. With an expected mechanical relay life of 10 million operations and an electrical life of 100,000 operations at rated load, the Model 274 offers sustained performance and reduced maintenance needs. It functions reliably across an operating temperature range of -20° to +131° F, suitable for various industrial environments. Power consumption is limited to 3W maximum.
