New PV connector from Amphenol Industrial achieves higher current rating, exceeds several UL requirements

By Chris Crowell January 31, 2022

Amphenol Industrial Sustainable Technologies has a new single pole power connector designed to exceed the performance of the UTX and H4 family of PV connectors. The Amphe-PV H4 Plus is dual-certified at 1500V DC to UL 6703 and IEC 62852.

These new solar connectors use Amphenol’s patented RADSOK technology to achieve higher current ratings, as well as to lower temperature rise and contact resistance, as compared to other contact methods on the market.

Some quick facts on its performance about UL requirements: The Amphe-PV H4 Plus lists thermal shock performance three times above that of UL requirements. It exceeds UL dry heat and damp heat exposure requirements by two times; and it surpasses UL humidity and freeze thermal cycling robustness requirements by three times.

The Amphe-PV H4 Plus features a ratcheting cable gland that prevents backspin after termination. It is designed with an enhanced sealing grommet and internal collet for better wet leakage performance and cable retention. The unit’s innovative sealing structure offers stable protection and IP68 (24 hours at 1 meter) performance.

Constructed of high-performance polymer material, this connector has an ambient temperature range of 40˚C to +85˚C, and upper limiting temperature of 120˚C. It is chemical resistant and has low moisture absorption. It accepts wire gauges from 14 AWG/2.5mm2 to 8 AWG/10mm2.
