Eaton Specification Sheet - PV15M-4A-CT
High‑voltage protection is built into PV15M-4A-CT with a 1500VDC rating and 4A amperage. This combination delivers fast overcurrent separation for solar strings, helping prevent insulation damage and potential arc faults that can lead to shutdowns or equipment damage. The device is compact enough to fit in standard inline fuse blocks, measuring 81.4 mm in height and 10.31 mm in diameter, and weighing 13 g for easy mounting in dense PV layouts. This product is well suited to utility-scale and commercial PV deployments. Crimp terminal termination simplifies field wiring and improves connection reliability. The robust crimp interface reduces termination errors during installation and maintenance, translating to fewer callbacks and faster commissioning. In practice, technicians benefit from predictable contact integrity when mounting protection in Eaton BMM fuse blocks or HEB inline holders, supporting consistent protection across multiple strings. Non‑indicating fuse indicators reduce visual checks and simplify status management in remote solar sites. With no external flag or LED that can degrade, maintenance teams can rely on electrical tests to confirm protection status, saving time during outages or routine inspections and ensuring uninterrupted PV protection in tough environments. Compatibility with BMM fuse blocks and HEB inline holders enables plug‑and‑play protection upgrades. This integration minimizes system redesign and accelerates retrofits in existing solar arrays, while maintaining Eaton Bussmann PV protection standards. The PV15M-4A-CT remains compatible with a broad range of standard photovoltaic protection configurations, reducing procurement complexity for project engineers. GB15166 certification and PV‑specific classification (Class gPV) address industry safety and reliability requirements for solar installations. This compliance supports risk management and insurer confidence while the 1500VDC rating aligns with modern high‑voltage PV strings for rooftop and utility-scale projects.

FAQs
PV15M-4A-CT is designed for plug‑and‑play integration within Eaton Bussmann BMM fuse blocks and HEB inline holders. It uses crimp terminals for secure field connections, enabling quick replacements without rewiring. This compatibility reduces project lead times and simplifies spare parts inventories for solar developers deploying modular PV protection assemblies.
Key specs include a 4 A amperage rating, 1500 VDC operating voltage, Class gPV construction, and a non-indicating fuse indicator. The 81.4 mm height, 10.31 mm diameter, and 13 g weight support straightforward mounting in inline fuse blocks, while the crimp terminal provides robust, code‑compliant terminations critical for reliable string protection in high‑voltage PV systems.
PV15M-4A-CT is suited for utility-scale and commercial PV installations that use 1500 V DC strings. It protects photovoltaic arrays against overcurrent events, supports rapid fault isolation, and helps maintain uptime in rooftop and ground-mounted configurations where high‑voltage protection is required. The inline form factor and compatibility with common Eaton protection blocks simplify scaling across large deployments.
PV15M-4A-CT carries GB15166 certification for safety and reliability within PV applications and is designed as Class gPV equipment for solar protection. This alignment with PV‑specific standards helps satisfy regulatory and insurer requirements for both new builds and retrofit projects. It is also suitable for 1500VDC standards used in modern PV systems.
Routine maintenance for photovoltaic fuses is minimal; the non‑indicating design reduces on-site checks, while the crimp terminal and compact form factor simplify replacements. Over time, reliable protection minimizes downtime, lowers repair costs, and supports faster project commissioning, delivering a favorable total cost of ownership for solar deployments.
