The Eaton PFR-W-70 is a summation current transformer with a 70 mm through-opening, intended to work with the PFR-5 earth-fault relay for residual-current protection on NZM1-4 circuit breakers. It carries a nominal primary current of 400 A and delivers a 5 A secondary suited to the relay input, rated for 690 V AC 50/60 Hz systems. Typical installations include distribution boards where sensitive residual-current detection is required together with a moulded-case circuit breaker.
