Amphenol Industrial H4 Plus Solar Connectors
Amphenol Industrial H4 Plus™ Solar Connectors are single-pole power connectors that are designed to exceed the performance of the UTX and H4 family of PV connectors. The Amphe-PV H4 Plus is dual-certified at 1500VDC to UL 6703 and IEC 62852, while the H4 Plus P2KV is built for 2000VDC photovoltaic systems. Designed for use in photovoltaic PV modules, inverters, and installations, these robustly constructed connectors are reliable, durable, and stable over a lifetime. The connectors offer robust thermal shock performance 3x above that of UL requirements; exceed UL dry heat and damp heat exposure requirements by 2x; and surpass UL humidity and freeze thermal cycling robustness requirements by 3x, making them extremely robust in the field.
Amphe-PV H4 Plus solar connectors use Amphenol’s patented RADSOK technology to achieve higher current ratings, as well as to lower temperature rise and contact resistance. The Amphe-PV H4 Plus components feature 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 1m) performance. Constructed of polymer material to ensure long-term stability, these connectors feature an ambient temperature range of -40°C to +85°C with and upper limiting temperature of +120°C. It is chemical-resistant and has low moisture absorption. It accepts wire gauges from 14AWG (2.5mm2) to 8AWG (10mm2).
H4 Plus P2KV connectors offer ultra-low contact resistance of ≤0.25mΩ, minimizing power loss and maintaining long-term system performance. Available in both field-assembled and pre-assembled configurations, these connectors are mating-compatible with H4 connector solutions, and the dedicated tooling supports reliable, repeatable installation. P2KV connectors accommodate cable diameters of Ø8.38mm to Ø11.0mm, provide IP68 protection when properly mated, and have flame-resistant UL 94V-0 construction.
