Control relay on three-phase lines, this relay detects when all phases are connected in the correct sequence and the asymmetry is less than the set value, the output relay R switches on and the yellow LED lights up. As soon as the phase sequence changes, the output relay switches off and the yellow LED goes out.

Electronic relay for control and monitoring of three-phase lines with an output contact. This relay allows to monitor the following parameters:

  • Phase sequence control. When all phases are connected in the correct sequence and the asymmetry is less than the set value, the output relay R switches on and the yellow LED lights up. As soon as there is a change in the phase sequence, the output relay switches off and the yellow LED goes out.

  • Phase failure monitoring. When a fault occurs in any of the three phases, the output relay R switches off and the yellow LED goes out.

  • Asymmetry control. When the asymmetry exceeds the set ASYM value, the output relay R switches off and the yellow LED goes out. The disconnection occurs even in the case of an asymmetry caused by the return voltage in a motor running on only two phases.
