Overview

Mersen HP15G3CC is a 1500VDC photovoltaic (PV) fuse engineered specifically for ground fault protection in PV systems. Rated at 3A, it is designed to safely interrupt low ground fault currents typical in PV arrays, with a low minimum breaking capacity of 1.35x the rated current. The Class G fuse, measuring 10x57mm, features a Crimp Cap terminal for solderless, in-line applications, allowing for overmold encapsulation of the fuse and wiring for enhanced durability and protection against environmental factors. Built to withstand continuous temperature and current cycling, it ensures reliable performance even in harsh environmental conditions, contributing to system longevity. The HP15G3CC is UL Listed to UL2579 and compliant with IEC 60269-6, making it suitable for use in off-grid or grid-tied PV systems, combiner boxes, and inverters. It is available in bulk packs of 176 units for convenient procurement. The recommended crimping tool for #10-12 AWG wires is the T&B Sta-Kon ERG4002, ensuring proper installation and connection integrity.
