Voltage Relay CP-730

The voltage relay CP-730 is used for monitoring the voltage of a three-phase network and protecting a single-phase receiver from the effects of voltage increase or decrease beyond the specified values.

• Operating potentiometers for the lower (U1) and upper (U2) voltage threshold for the three phases.
• Green LED light indicates the correct voltage of the receiver, while changes above or below the specified limits activate the relay.
• Red LED signals a voltage drop below U1 or an increase above U2.
• Activation time setting for the lower limit U1 with potentiometer T.
• Power supply up to 450 V~, protection of the receiver from unstable voltage.
• Automatic locking of the relay in case of multiple voltage changes.
• Locking status is indicated by the yellow LED.

Technical specifications: power supply 3×(50÷450V)+N, load current 10A.
