Amphenol H4 PV Connector is TUV-certified to 1500V
Amphenol Industrial Global Operations’ photovoltaic (PV) H4 connector is TUV-certified to 1500V and meets the requirements of IEC EN 50521, Certificate #: R-72123201. This new rating approval, combined with the existing 1000V by UL, further establishes Amphenol’s H4 series of PV connectors as the technology leader for PV systems worldwide.
PV module manufacturers can now offer 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.
Used in large scale utility and commercial PV installations, the H4 not only adheres to UL requirements in the US up to 1000V, but meets IEC requirements for use up to 1500V in markets where IEC is recognized, including the European Union, parts of Asia, India, and the Middle East.
Amphenol’s H4 connectors feature RADSOK technology, and offer the highest current ratings and lowest contact resistance, resulting in lower power losses and improved reliability. They are compatible with industry-standard connectors.
The upgraded connectors 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 32A, 12 AWG rated at 40A, 10 AWG rated at 44A, and 8 AWG rated at 65A.
