Mains frequency: 50 Hz, 60 Hz, and 400 Hz (40 Hz…500 Hz)
Prevents startup in the event of a missing phase.
Protects sensitive equipment from power supply faults.
Use of the neutral wire is optional in three-phase systems
Phase-by-phase status relay output
Contactor control, PLC input
Connecting the relays in series provides a summary relay output
