Amphenol has designed a low cost stamped and formed contact option for its H4 solar connector, complementing the already existing machined contact. These low cost contacts are suited for use in large scale PV installations as well as with 1000 V PV modules. All H4 connectors, regardless of contact type, are the only field installable PV connectors on the market approved by UL for use up to 1000 V. UL6703 1000 V testing includes performance after temperature cycling (-40ºC to 90ºC) and humidity freeze (85 ºC/85% relative humidity to -40ºC). The H4 connector also meets the IEC 1000 V standard and can be used in existing systems as well as in new ones that require more voltage without having to increase cable size. The dual-rated (UL/TUV) PV connector features Amphenol's RADSOK technology, offering higher current carrying capacity and lower contact resistance. The RoHS-compliant, CSA approved connector also meets NEC 2008 requirements without the need for extra locking collars or locking sleeves.
