Manufacturer source discovery; confirm the exact regional equipment configuration and certification separately. Use the manufacturer configuration named Electro relay sensor CT Horiz. ## In plain English ### What the equipment does A current transformer, or CT, produces a smaller measuring current related to the alternating current in a power conductor. Meters and protection relays use that signal to monitor the circuit. ### A simple example Use SB115305_2D-front.dxf (revision 1.0) to insert the supplied editable drawing into your layout. ### What the drawings help you do Use SB115305_2D-front.dxf (revision 1.0) to insert the supplied editable drawing into your layout. Use SB115305_3D-simplified.stp (revision 1.0) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified SB115305_3D-simplified.stp. ### Before using this reference - Match Schneider Electric Electro relay sensor CT Horiz and the exact source filename shown above. - The supplied model has approximate X × Y × Z bounds of 110.4 × 74.4 × 60.5 mm.
