The 1597D4MPRHTPC is a clear Italtronic top cover with inlay for DIN 4 enclosures in the 1597DM Series. Its short description is "D4 TOP PNL INLAY CLEAR, CLIPS", making it the transparent version of the clip-in inlay top panel. It is drawn on the grey Module 4 enclosure 1597DIN4MH53, and the drawing marks the top cover as not included with the enclosure.

It is made from PC with a UL94 V-2 flame rating, as the series specifies for clear accessories, and measures 2.63 in x 1.65 in x 0.1 in (67 mm x 42 mm x 3 mm). Shipping weight is 0.01 lbs (0.00 kg). It is RoHS and REACH compliant.

The gray PC-ABS equivalent is the 1597D4MPRH; DIN 4 also has flat gray and clear covers and a clear hinged cover, 1597D4MPHGTPC. The enclosure ships with base, cover and DIN clip in PPO. In the 1597DM range the DIN group number refers to the number of terminals on each side. Hammond notes that some accessories are not compatible with all enclosures in a DIN size group; confirm fit against the enclosure drawing.

Use the 1597D4MPRHTPC where the inside of a DIN rail housing for PCBs or terminal blocks should stay visible. Some chemicals can damage or weaken plastic, so check the manufacturer's Chemical Resistance Statement before using solvents, thread-locking compounds or cutting fluids near the part.
