The new 3-phase monitoring relay from Teledyne is designed to meet the requirements of electrical engineers, panel builders and automation engineers. It is designed to protect motors and other 3-phase powered machinery from the damaging effects of phase anomalies and undervoltage. The monitoring relay addresses critical power quality issues such as incorrect phase sequence, total and partial phase loss, and undervoltage. Key features include monitoring to ensure all three phases are present and in correct sequence, adjustable undervoltage detection, a compact DIN-rail 17.5mm housing, monitoring voltage range of 208 to 480V AC, LED indication for power supply and output relay on, and simple wiring for easy installation.
