FAQs
PV-32ANH1 is designed for NH1 fuse bases such as the SD1-D-PV. To install, mount the base in the enclosure, align the fuse contacts with the blade terminals, and press the fuse link firmly until the status indicator confirms seating. Verify DC circuit continuity and ensure the 1000 Vdc rating is not exceeded. The dual indicator aids quick verification after installation.
A 50 kAIC interrupt rating indicates the fuse can safely interrupt short-circuit currents up to 50 kiloamps at ambient conditions without damaging the equipment. In PV applications, this provides high fault tolerance for string and combiner faults, reducing the risk of collateral damage and improving overall system resilience during surge events.
PV-32ANH1 is well-suited for PV array protection with an NH1 form factor and 32 A rating. For utility-scale installations, use in string-level protection within combiners and disconnects is common, with multiple devices in series or in parallel as per layout. Always respect the 1000 Vdc limit and verify the base compatibility (SD1-D-PV NH) for reliable operation.
Yes. PV-32ANH1 carries UL listing and IEC 60269 certification, meeting CE marking and RoHS compliance for global deployment. CSA Certified status is also listed, supporting cross-border procurement and reducing regulatory risk across multinational solar projects.
The dual fuse status indicator reduces diagnostic time by providing immediate fault visibility, while the 50 kAIC rating and 32 A capacity minimize unplanned outages. Built for NH1 bases and SD1-D-PV compatibility, it lowers spare-part complexity and supports standardized protection across sites, delivering lower maintenance costs and improved ROI over time.
