FAQs
PV-32A14F is designed for direct compatibility with the CHPV14 modular fuse holder, enabling quick plug-in protection for PV strings. This reduces on-site wiring complexity and service time, while maintaining secure electrical connections and consistent protection across string sections.
The PV-32A14F is rated for 32 A at 1000 V DC, with an interrupt rating of 10 kAIC (and 30 kAIC in higher fault scenarios). It features a PV-class fuse type (PV-A14F) and a Pre-arc I2T of 120, delivering reliable response in PV string fault events.
Yes. It is specifically designed for photovoltaic strings and provides UL Listed, IEC rated protection for DC solar circuits. Its 1000 Vdc rating and modular compatibility make it suitable for both rooftop arrays and small to mid-size utility-scale projects, with CCC pending in some markets.
The fuse measures 14 x 51 mm (length 51 mm, width 15 mm, height 15 mm) and weighs about 21.5 g. It is non-indicating, which suits dense installations where visual indicators are managed by other equipment, and it aligns with CHPV14 holders for straightforward mounting.
PV-32A14F ships with UL Listed and IEC rated certifications, with CCC pending where applicable. Technical datasheets and catalogs are available, including the 14x51 mm PV fuselinks data sheet and related declarations of conformity to support compliance and procurement processes.
