Original DXF drawing for S1 residual current release RC 211-212/1 bottom mounting Fixed version Rear terminals; ABB document ITSCE-601855341 ## 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 When coordinating S1 residual current release RC 211-212/1 bottom mounting Fixed version Rear terminals in switchrooms, place the documented arrangement beside the adjacent equipment and compare its fixing and connection access with the source drawing. ### What the drawings help you do Use ITSCE_601855341.dxf for S1 residual current release RC 211-212/1 bottom mounting Fixed version Rear terminals. DXF is the supplied drawing format; the preview shows the source sheet. A matching STEP model is not included. Match ABB document ITSCE-601855341 revision E when checking a replacement. ### Before using this reference - Match the configuration named “S1 residual current release RC 211-212/1 bottom mounting Fixed version Rear terminals”; terminal direction, mounting version and pole options can change the outline. - Use ABB document ITSCE-601855341, revision E, to check the mounting and connection details before placing this item in the assembly. - The source names rear terminals.
