• Monitor for overcurrents or undercurrents.
• Manual resetting and automatically resetting supported by one
• Startup lock and operating time can be set separately.
• One SPDT output relay, 6 A at 250 VAC (resistive load).
• Output relay can be switched between normally open and
• Process control signal (4 to 20 mA) and commercial CT input
• Output status can be monitored using LED indicator.
• Inputs are isolated from the power supply.
