There are various types of photovoltaic fuse holders, and the specifications are also different.
1. Type
According to the installation type
Panel mount fuse holder: designed for direct installation on the panel or equipment, easy to operate and observe.
PCB mount fuse holder: designed for printed circuit boards (PCBs), fixed to the circuit board by welding or plug-in.
Lead fuse holder: connected to the circuit through leads, suitable for situations where flexible circuit layout is required.
Guide rail fuse holder: designed for guide rail installation, convenient for unified management and maintenance inside or outside the equipment. For example, the LOVATO brand fuse holder is designed for 35mm DIN rail installation.
Automotive fuse holder: a fuse holder designed for automotive electrical systems, with specific size and electrical performance requirements.
According to the size of the fuse
Large fuse holder: suitable for larger fuses, usually used in systems carrying higher currents.
Medium fuse holder: suitable for medium-sized fuses, suitable for the protection of general electrical equipment.
Small fuse holder: suitable for smaller fuses, usually used for the protection of small electronic devices or low-voltage circuits.
Classification by functional characteristics
Fuse holder with status indicator: The working status of the fuse is displayed by the indicator light, which is convenient for timely detection of faults.
Waterproof and dustproof fuse holder: It has waterproof and dustproof functions and is suitable for outdoor or humid environments.
High temperature resistant fuse holder: Made of high temperature resistant materials, it is suitable for high temperature working environment.
2. Specifications
The specifications of photovoltaic fuse holders mainly include rated voltage, rated current, fuse size, etc. The following are some common specification parameters:
Rated voltage: The rated voltage of photovoltaic fuse holders is usually higher to adapt to the high voltage characteristics of photovoltaic systems. Common rated voltages include 600V, 750V, 1000V, 1250V and 1500V, etc.
Rated current: The rated current of the fuse holder varies according to the current demand of the photovoltaic system. Common rated currents range from a few amperes to tens of amperes. For example, a 10x38mm fuse may have a different current rating of 232A, while a 10x85mm and 14x85mm fuse may have a different current rating of 632A.
Fuse Size: The size of the fuse holder usually matches the fuse installed. Common fuse sizes include 10x38mm, 10x85mm, and 14x85mm, etc.
