Metz Connect Cos-Phi Monitoring Relay

The cosinus F aut. controller is used for recognising an underload (without sensor). The monitoring effected through recognising the phase shift between current and voltage. The phase angle shifts with the loading of a motor. It can also be used along with a frequency converter (frequency 2...200 Hz). Motor current from 0,2...10 A, bigger motors can be connected through current transformers. Response value and time are adjustable. Connections with lift terminals and underplugging protection. Cross-section of the connection, 2,5 mm². Slender construction: 22,5 mm, can be snapped onto DIN-rail.
