| Zusammenfassung: | A ground fault trip unit of the three-pole type, comprises a fourth conductor passing through the differential transformer. The fourth conductor is connected to terminals located on a different face from that of the terminals of the other three conductors. The same ground fault trip unit can be associated with a three-pole breaking device, in which case the fourth conductor is not use, and with a four-pole device whose fourth pole is connected to the fourth conductor of the ground fault trip unit. |
