Broyce Control Phase Monitoring Relay, 3 Phase, 320 → 490V ac, DIN Rail

The Broyce Control monitors it’s own three-phase supply and indicates the status of each connected phase along with whether the phase sequence is correct or not. If a phase is lost, the corresponding phase present LED extinguishes and colour of the status LED changes from green “Correct” to red “Incorrect”. If the phase sequence is reversed, only the status LED changes from green “Correct” to red “Incorrect”.

Ideal for control panels, switchboards, distribution systems that require visual indication and status of a 3-phase power supply
Used to indicate that all phases are present and phase sequence is correct (or incorrect)
Designed for use on 3-phase, 3-wire supplies
