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
