Phase control relays provide continuous monitoring of three-phase network parameters and protection of equipment in case of emergency modes: overvoltage, undervoltage, voltage asymmetry, phase sequence, and phase failure.
Devices are widely used in automation systems, automatic transfer switches (ATS), as well as for protecting electric motors, pumps, compressors, and other equipment critical to power supply stability.
*The list of controlled parameters depends on the device modification. Detailed characteristics are in the product data sheet.
