Overview

The Mersen HP15P32CC is a 1500VDC, 32A photovoltaic (PV) fuse engineered for high-amperage PV circuits in off-grid and grid-tied systems. This 20x65mm fuse features Crimp Cap (CC) terminals, enabling solderless, overmold-encapsulated wire-to-fuse connections ideal for in-line applications. With a low minimum breaking capacity of 1.35x rated current, it safely interrupts typical low fault currents common in PV arrays. The HP15P32CC is UL Listed to UL2579, CSA Component Pending, and compliant with IEC 60269-6, ensuring global acceptance. Its durable construction withstands harsh cyclical loads and thermal extremes, providing reliable protection for PV string wiring, combiner boxes, inverters, and battery charge controllers. Designed for string/array-level protection, this fuse meets the demand for higher efficiency in 1500VDC utility-scale systems. The Crimp Cap terminal option simplifies installation by eliminating soldering while maintaining secure, encapsulated connections. With a Short-Circuit Current Rating (SCCR) of 50kA, it delivers robust fault protection in demanding PV environments. The HP15P32CC is part of Mersen’s HelioProtection® fuse line, trusted for safeguarding PV systems from unexpected ground and line faults.
