What is the intended use of UL Type 1 enclosures for KDR or KLR?

When your application is indoors and requires a larger space for wire bending, UL Type 1 enclosures are the optimal choice. UL Type 1 enclosures provide protection against a limited amount of falling dirt as well as a vent slot size that provides cooling for the unit. This larger enclosure provides the necessary space for heat dissipation.
