3-Phase Monitor
The EX246 3-Phase Monitor offers essential protection for industrial electrical systems. This device continuously monitors for critical conditions including phase loss, phase reversal, low voltage, and over voltage, ensuring operational integrity. Its automatic reset functionality minimizes downtime by restoring operation without manual intervention once faults clear. With a robust 5-year unconditional warranty and a mechanical relay life of 10 million operations, the EX246 provides long-term reliability. Precise monitoring is maintained with a repeat accuracy of ±0.1% of the set point and a rapid 50ms response time. This unit is designed for consistent performance in demanding environments, operating from -20° to +131° F with 0-97% humidity tolerance. Its SPDT 10A contact rating at 240VAC resistive ensures reliable switching for various control applications. The compact design and ABS plastic enclosure contribute to its utility in diverse industrial settings.
