Suntree DC Solar String Fuses with Holder

Product Overview

Suntree DC Solar String Fuses with Holder are protective accessories designed for solar PV systems and DC electrical installations. They help protect solar panel strings from overcurrent, short circuits, and PV array faults by disconnecting the circuit when unsafe current levels occur. The range includes 16A, 20A, and 32A fuse options, with 1000V DC rating and compact 10x38mm fuse link size, making them suitable for solar combiner boxes, DC distribution boards, inverter protection, and other solar DC applications. The 32A option is supplied with a holder for easier installation and replacement, while the 20A DC link with 1-pole holder is also listed as suitable for protecting PV strings from PV array faults.

Designed for Solar PV String Protection

In a solar PV system, each panel string carries direct current from the solar array to the inverter, charge controller, or combiner box. If a fault occurs, excess current can damage cables, panels, or connected equipment. Suntree DC string fuses are designed to interrupt that unsafe current and help protect the system. The 16A model is rated at 1000V DC, uses a 10x38mm fuse size, supports DIN rail mounting, and has a breaking capacity of 33kA, making it suitable for modern PV systems. (Solar Shop Africa)
