- Information on the PF7 Phase Sequence Monitoring Relay
The PF7 phase sequence monitoring relay has been specifically developed for installation in switchgear used in potentially explosive atmospheres in industrial plants.
- Due to the 3 phase AC, 50 Hz, mains voltage to be monitored with a max. possible rated operating voltage of max. 1,250 V AC (1,140 V AC +10%) the entire installed electronics inside the protective housing were fully encapsulated with insulating casting compound due to the high dielectric strength of the measuring input.
– The test voltage of the manufactured module is: 3 AC, 50 Hz, 1250 VA AC
