AC Current with Adjustable Time Delay

General Details

250 series ac current protectors provide continuous surveillance of the monitored circuit. When the current moves outside the set point limit for longer than the time delay, the relay operates. The protector can be used to monitor over and under-current conditions, load detection and for monitoring electric heating systems. An illuminated LED indicates when the relay is energized. For three-phase systems, the sequence of connection is not important.
