3-Phase Monitor
The MODEL 259 3-Phase Monitor, SKU EX259, provides essential protection for industrial systems. This device features adjustable trip and restart delays, allowing for precise control over operational parameters. Its adjustable voltage level accommodates diverse application requirements, operating nominally at 380VAC with a 300-400VAC range. With DPDT 600VAC output contacts, it ensures reliable switching capabilities for critical loads. The monitor offers robust transient protection of 2500V for 10ms, safeguarding connected equipment from electrical disturbances. Operating efficiently across a -20° to +131° F temperature range and tolerating 0-97% humidity without condensation, it maintains consistent performance in challenging industrial environments. The unit's 5-year unconditional warranty underscores its design for sustained utility and operational longevity. Its repeat accuracy of ± 0.1% ensures consistent monitoring.
