What does HARTING UL 508 solutions under UL 2237 mean?

HARTING now offers focused product solutions that are fully compliant with the UL 508 (508A, 508C) certification standard for “Industrial Control Equipment”. This represents a significant advance for North American OEMs and anywhere else where UL 508 certification is a practical necessity. It will expand the use of connector-based cable assemblies or components in industrial electrical control cabinets. HARTING has created two possibilities for using its industrial connectors to make electrical connections in UL 508 control panels, switchgear and other control systems.

The first is the creation of an extensive range of “UL-Listed”, pre-assembled, connector-based cable assemblies that meet the requirements of UL 2237 (“PVVA” section), a complementary standard to UL 508 that governs multi-point connections of power cables in industrial machinery. The second is made possible through the newly launched “PVVA2” section of UL 2237, which was established by UL at the request of HARTING. It allows for field assembly using individual “UL-Recognized” components. The PVVA2 classification facilitates the use of connectors in a UL 508-certified cabinet, which in turn will deliver benefits throughout all stages of product design, fabrication, testing and commissioning, with enormous time and cost savings over hard-wired connections. HARTING connectors are the only rectangle connectors that have undergone rigorous testing by UL to gain “ULRecognized” (PVVA2) status, which also makes them suitable for incorporation in PVVA cable assemblies. A wide range of HARTING connectors now have “UL-Recognized” status, and many more HARTING products will be added to both the PVVA and PVVA2 lists in the months and years to come.
