Acti9 Monitoring Relays
Range of relays for current, voltage and phase control, time delay relays with frontal regulation by trimmer and fault tripping indication
Schneider Electric Phase Control Relay, 8A Current Rating, 5 to 25% Phase Asymmetry Setting - Acti9 Series - A9E21180
Get the right balance of power with this phase control relay from Schneider Electric. It detects asymmetry along the line of three-phase circuits, protecting your equipment from electrical damage. The red indicator on the front gives you a clear signal when there's a loss of phase or an inversion. A rotary knob means you can tweak the asymmetry trip level. You can set it between 5% and 25% to suit your devices, giving you a way to monitor and control the power of three-phase motors. Adjustments are done with a screwdriver, making the relay a doddle to use.

What's the difference between phase monitoring and voltage monitoring relays?
Voltage monitoring relays alert you when a specific voltage threshold is reached rather than when your system is out of balance.
