Amphenol Industrial Operations (PV) H4 connector is now TUV-certified to 1500V and meets the requirements of IEC EN 50521, Certificate: R-72123201. This new rating approval, combined with the existing 1000 V by UL, establishes the H4 series of PV connectors as suitable for PV systems worldwide.
Certification means that PV module manufacturers can now offer its global customers a single field-installable connector that meets the highest voltage rating of both UL (Underwriters Laboratories) and IEC (International Electrotechnical Commission). EPC (engineering, procurement and construction) firms around the world can now use the H4 for cable assemblies and interconnections to meet the highest voltage standards available.
The H4 not only adheres to UL requirements in the US up to 1000 V, but meets IEC requirements for use up to 1500 V in markets where IEC is recognised including the European Union, parts of Asia, India and the Middle East.
The connectors feature RADSOK technology that offers the highest current ratings and lowest contact resistance resulting in lower power losses and improved reliability. They are compatible with industry-standard connectors and meet NEC 2011 requirements without the need for extra locking collars or locking sleeves. They are RoHS-compliant and use a simple unlocking tool for easy mating and unmating in the field. The H4 is available in four different gauges including 14 AWG rated at 32 A, 12 AWG rated at 40 A, 10 AWG rated at 44 A and 8 AWG rated at 65 A.
