| Zusammenfassung: | A magnetic flux concentrator shield (94) is disclosed for use with magnetic flux sensors (98) in an overload relay (141) for multiple pole electromagnetic contactor (10, 12) applications. The magnetic flux concentrating shield (94) has slotted layers (96) of laminated members. The layers (96) have a series of pole shielding slots (144) which concentrate magnetic flux generated by conductors (16) carrying current through conductor apertures (103) in each layer (96). Magnetic flux sensors (98) are positioned within air gaps (132) within each pole (130) of the shield (94). By shielding the generated magnetic flux from reaching the magnetic flux sensor (98) of another pole (130), the pole shielding slots (144) minimize cross pole magnetic flux sensor interference. |
