Selection & installation notes
- Element type, protective class and terminal construction conflict between page text and product images. Request the exact model datasheet and wiring drawing before selection or connection.
- The selection chart defines two usage configurations but does not establish a safe field switching procedure. Do not rewire under power or infer terminal connections from the order code.
- The general naming image uses a hyphen before K while the selection chart omits it. Order codes above follow the selection chart; confirm the complete manufacturer code.
- Fan versions accept only their listed AC or DC supply; the no-fan AC/DC range does not extend to fan versions.
- Reference dimensions are explicitly estimated in the source. Obtain a production drawing. Use ON/OFF control, allow clearance around hot surfaces, and confirm thermal protection and inrush with the manufacturer.
