HONEYWELL 51307687-176 PCB Board
Made in U.S.A
Honeywell 51307687-176 Phase Monitoring Relay Module
Missing phase discharge: Detect the lack of phase at a terminal in a three-phase system. When it detects a fault in one of the three phases, the relay trips and disconnects the circuit at its output.
Phase monitoring/loss relays are used in systems where three phases are required for proper operation. If one or more stages are missing, the entire system will stop working. Therefore, these relays are an effective preventive measure for electrical and electronic components.
For example, a mixer uses a three-phase electric motor for its mixing operation. If the three-phase does not exist, the motor will not operate. In addition to motor applications, phase monitoring/loss relays are also used in transformer and generator applications.
