Abstract (en)
[origin: EP0320411A1] A differential release unit 12 of the three-pole type comprises a fourth conductor 32 traversing the differential transformer 24. The fourth conductor 32 is connected to terminals 34 disposed on a different face from that of the terminals of the other three conductors. The same differential release unit 12 may be associated with a three-pole cut-off device in which case the fourth conductor 32 is not used, and with a four-pole device 42 whose fourth pole 44 is connected to the fourth conductor 32 of the differential release unit 12. <IMAGE>
