Model EX264-380 3-Phase Monitor
The Model EX264-380 3-Phase Monitor provides essential protection for industrial systems. Operating at a nominal 380VAC with an adjustment range of 300-400V, this unit safeguards equipment against critical power anomalies. It detects phase loss, low voltage, and phase reversal, preventing potential damage and operational downtime. The monitor features robust output contacts, including one SPST N.O. and one SPST N.C., rated for 10 amps at 240VAC resistive, ensuring reliable control. With a mechanical relay life of 10 million operations and an electrical life of 100,000 operations at rated load, the EX264-380 offers sustained performance. Its response time ranges from 0.2 to 20 seconds, with a rapid 0.15-second reset. The unit operates effectively from -20° to +130° F with 0-97% humidity tolerance. An automatic reset function and a 5-year unconditional warranty underscore its utility and dependability in demanding environments.
