Manufacturer source discovery; confirm the exact regional equipment configuration and certification separately. Use the manufacturer configuration named NHP DTRD RCBO. ## In plain English ### What the equipment does A residual-current device compares the current leaving a circuit with the current returning. A difference can indicate current flowing along an unintended path, causing the device to trip. An RCBO also provides overcurrent protection. ### A simple example Use NHP-DTRD-RCBO-2D-CAD-Block.dwg to insert the supplied editable drawing into your layout. ### What the drawings help you do Use NHP-DTRD-RCBO-2D-CAD-Block.dwg to insert the supplied editable drawing into your layout. Use NHP-DTRD-RCBO-3D-CAD-Block.stp to place the original solid geometry in your 3D assembly. ### Before using this reference - Match NHP DIN-T DTRD RCBO and the exact source filename shown above. - The supplied model has approximate X × Y × Z bounds of 35 × 90 × 74.5 mm. These are source-model axes; mounting holes and installation clearances must come from the matching manufacturer sheet. - The orthographic views are projected from the manufacturer 3D geometry. They are labelled separately from original dimensioned sheets and do not add manufacturer dimensions. - The source was checked on 2026-11-11.
