The 1597D4MPHTPC is a flat, clear Italtronic top cover for DIN 4 enclosures in the 1597DM Series of DIN rail mounted enclosures. Its short description, "D4 TOP PANEL FLAT CLEAR, CLIPS", marks it as the transparent version of the flat clip-in top panel. The DIN 4 drawing shows it on the grey Module 4 enclosure 1597DIN4MH53 and notes that the top cover is not included with the enclosure.

It is PC with a UL94 V-2 flame rating, the series material for clear accessories. The cover measures 2.63 in x 1.65 in x 0.09 in (67 mm x 42 mm x 2 mm), the same footprint as the gray flat 1597D4MPH. Shipping weight is 0.01 lbs (0.00 kg), and it is RoHS and REACH compliant.

A clear flat top is useful when status LEDs or labels inside the enclosure must stay visible after installation. Other DIN 4 choices are the inlay covers 1597D4MPRH and 1597D4MPRHTPC and the hinged 1597D4MPHGTPC. The enclosure itself includes base, cover and DIN clip, made from PPO. Hammond notes that some accessories are not compatible with every enclosure in a DIN size group, so check the enclosure drawing.

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.
