FAQs
CHPV1U is designed for modular protection in standard PV enclosures and junction boxes. Install with secure mounting, proper cable routing, and correct fuse links per the Eaton datasheet. Ensure conductor sizing aligns with the 30 A rating and observe the -20 °C to 120 °C operating range for outdoor environments. Regular inspection of connectors reduces contact resistance and maintains reliability.
The CHPV1U is rated for 30 A continuous current and 1000 Vdc maximum voltage. It is a single-pole, modular fuse holder designed for photovoltaic protection. These ratings support protection of PV strings and related equipment, while enabling straightforward selection within standard Bussmann series protection schemes.
Yes. The CHPV1U’s single-pole modular design, plus its 30 A/1000 Vdc rating, makes it well-suited for rooftop arrays, ground-mounted systems, inverters interfaces, and PV combiner boxes. Its compact form and straightforward wiring help minimize installation time and allow scalable protection as PV layouts grow or reconfigure.
Compliance documentation includes RoHS compliance and UKCA declarations for cylindrical photovoltaic fuse-links. Eaton also provides specification sheets (CHPV1U datasheet) and related technical data to assist with supplier qualification, installation guidance, and regulatory reviews in European and UK markets.
Maintenance benefits stem from a robust, single-pole modular design that reduces wiring complexity and potential fault points. A dependable overcurrent protection device minimizes unplanned downtime in solar plants, which translates to lower maintenance costs and improved system availability, contributing to a favorable total cost of ownership over the system life.
