The 1597D4MTC6 is an Italtronic terminal insert with holes for DIN 4 enclosures in the 1597DM Series of DIN rail mounted enclosures. The series accessory table lists it as the DIN 4 terminal cover "With Holes", and the DIN 4 top-cover drawing lists it among the accessories for the grey Module 4 enclosure 1597DIN4MH53.

It is moulded from PC-ABS with a UL94 V-0 flame rating and measures 2.77 in x 0.54 in x 0.79 in (70 mm x 14 mm x 20 mm). Shipping weight is 0.01 lbs (0.00 kg), and it is RoHS and REACH compliant.

In the 1597DM range, DIN group numbers refer to the number of terminals on each side of the enclosure. For DIN 4 you can also choose punch-out holes (1597D4MTCKO), a bus connector (1597D4MBC) or an inside terminal cover (1597D4MHSC). The accessory table does not list a blank closed cover for DIN 4. Hammond notes that some accessories are not compatible with all enclosures in a DIN size group, so check the enclosure drawing before ordering.

The 1597D4MTC6 is a practical choice for integrators and OEM engineers who need pre-holed terminal access on a DIN 4 housing for printed circuit boards and terminal blocks. 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.
