COS-2/400V

• Relay monitors phase shift between current and voltage in 3-phase or 1-phase networks - evaluates COS fí (replacement COS-1).
• The relay is designed to monitor overload/relieve the motors.
• Relay is designed for 3 x 400/230 V circuits.
• Galvanically isolated power supply AC 230 V, AC 110 V, AC 400 V or AC/DC 24 V.
• Adjustable upper and lower level COS fí.
• Possibility to extend the current range using a current transformer.
• Two output relays (for each level independent).
• Adjustable delay eliminating engine start-up
