Original STEP 3D geometry for OSS250G1SH/1; ABB document OSS250G1SH/1.STP ## In plain English ### What the equipment does A terminal provides an identified point for joining wires to equipment or to other wires. Terminal strips organise those connections so they can be wired and checked. ### A simple example When coordinating OSS250G1SH/1 in switchrooms, place the documented arrangement beside the adjacent equipment and compare its fixing and connection access with the source drawing. The supplied model spans 51.8 × 108.0 × 53.0 mm along its own X, Y and Z axes. ### What the drawings help you do Use OSS250G1SH_1.stp for OSS250G1SH/1. STEP is the supplied editable 3D exchange file; the browser model is a simplified display preview. Match ABB document OSS250G1SH/1.STP revision A when checking a replacement. ### Before using this reference - Match the configuration named “OSS250G1SH/1”; terminal direction, mounting version and pole options can change the outline. - Use ABB document OSS250G1SH/1.STP, revision A, to check the mounting and connection details before placing this item in the assembly. - The supplied model spans 51.8 × 108.0 × 53.0 mm along its own X, Y and Z axes.
