275-5-24VAC-A
The Model 275 Single Phase Current Monitor offers reliable overcurrent protection for critical systems. Designed for panel mounting, it integrates seamlessly into existing setups. Its compatibility with standard current transformers simplifies installation. The unit features a 1-5 amp current range and an adjustable trip delay from 0.2 to 20 seconds, allowing for precise system response. With a repeat accuracy of 1% maximum and transient protection up to 2500V for 10ms, it ensures consistent performance. The monitor operates across a wide temperature range of -20° to +131° F, maintaining functionality in diverse industrial environments. Its robust design and clear overcurrent and tripped indicators provide essential operational feedback. This device supports both automatic and manual reset options, enhancing operational flexibility. The SPDT 10A at 240VAC resistive contact rating and an electrical relay life of 100,000 operations at rated load underscore its durability.
The Model 275 Single Phase Current Monitor is designed for monitoring
alternating current in the range of 1-5 amps, at 50 to 400 Hz. The Model
275 provides a contact transfer when the set current level is exceeded
for a period longer than the time delay. The OVER-CURRENT indicator
illuminates immediately. After the time delay, the TRIPPED indicator
lights and the relay contact transfers. This device can directly monitor
AC currents in the range of 1 to 5 amps; 50 to 400 Hz. Matching
transformers are available to extend the use of this monitor to most any
current range. The Model 275 is available with automatic or manual
reset. Operating power is supplied by separate 24 or 120 volt power supply.
