Photovoltaic designers have been confidently incorporating Hollyland fuse products into their applications. Solar fuses protect the PV system wiring from getting too hot and catching fire. A solar fuse is a specialized fuse used in photovoltaic (PV) or solar power systems. These fuses are commonly referred to as PV fuses, solar PV fuses, fusible PV fuses, and solar panel fuses.
The main components of a standard fuse unit consist of the following items:
- Metal fuse element
- Set of contacts
- Support body
The major two categories of fuses include:
- Low Voltage Fuses
- High Voltage Fuses
In order to understand Low voltage fuses better, we can further classify it further into:
- Semi Enclosed or Rewireable Type
- Totally enclosed or Cartridge Type
The main usage of fuse is for the protection of the circuit. In a real term scenario, the current flowing through the wires may not be uniform at times. In such cases, your device could get overheated. There is also the chance of a fire if the fuse is not installed.
While the technology has advanced with the usage of circuit breaker, fuses are still used in a number of places like cars and basic electrical components.
The basic purpose of the fuse is to protect and is composed of an alloy which has a low melting point. A strip of this fuse is placed in series with the circuit. The working principle is that if the current is in excess then the strip would melt and break the circuit. There are different variants of fuse boxes available with different types of circuit breaking. For instance, in the case of slow blow fuses, a small overload is carried for some period without the circuit been broken.
Other fuse boxes are designed to break the circuit rapidly. The selection is based upon the kind of device and also the fluctuation level of the current.
- A fuse is a small, thin conductor designed to melt and separate into two pieces for the purpose of breaking a circuit in the event of excessive current.
- A circuit breaker is a specially designed switch that automatically opens to interrupt circuit current in the event of an overcurrent condition. They can be “tripped” (opened) thermally, by magnetic fields, or by external devices called “protective relays,” depending on the design of breaker, its size, and the application.
- Fuses are primarily rated in terms of maximum current, but are also rated in terms of how much voltage drop they will safely withstand after interrupting a circuit.
- Fuses can be designed to blow fast, slow, or anywhere in between for the same maximum level of current.
- The best place to install a fuse in a grounded power system is on the ungrounded conductor path to the load. That way, when the fuse blows there will only be the grounded (safe) conductor still connected to the load, making it safer for people to be around.
