Product Overview

String Fuses Complete with Holder are solar protection accessories designed to protect individual PV strings from overcurrent and short-circuit faults. They are commonly installed in solar combiner boxes, DC distribution boards, and PV protection panels to help safeguard solar panels, cables, charge controllers, and inverters.

Designed for Solar PV Protection

In a solar system, each string of panels carries DC current. If a fault occurs, excessive current can damage cables or connected equipment. These string fuses help interrupt the circuit when the current exceeds the safe limit, reducing the risk of equipment damage and improving the safety of the entire solar installation.

Complete Fuse and Holder Setup

This product comes as a complete unit with a fuse holder and compatible fuse, making installation easier for electricians and solar technicians. The holder allows the fuse to be mounted neatly inside a distribution board or combiner box while also making replacement more convenient when needed.

Key Features

Reliable Overcurrent Protection

The fuse helps protect solar PV strings from overcurrent, reverse current, and short-circuit conditions that may occur during system faults.

Complete with Holder

The included fuse holder provides a secure mounting point for the fuse, making the setup easier to install and maintain.

Suitable for DC Solar Systems

It is designed for use in DC solar applications, especially where individual PV string protection is required.

Easy Maintenance

The fuse can be replaced when necessary, allowing technicians to restore protection without replacing the whole protection setup.

Compact Panel Installation

Its compact design makes it suitable for installation in solar combiner boxes, DC distribution boards, and electrical enclosures.

Suitable Applications

String Fuses Complete with Holder can be used in solar PV systems, combiner boxes, inverter input protection, charge controller protection, DC distribution boards, off-grid solar systems, hybrid solar systems, and commercial or residential solar installations.

Benefits
