All you should know about Cartridge Ceramic Fuse
What is the function of the cartridge ceramic fuse?
They are used as safety devices, designed to protect electrical equipment from overloads and short circuits.
There is a metal strip inside the fuse that is connected to the two metal ends of the fuse body. Under a short or fault anywhere in the circuit, or the circuit is overloaded, the metal strip or connection heats up and melts rapidly, breaking the circuit and cutting off the power to prevent damage. When a fuse blows, the circuit is broken.
What’s the cartridge ceramic fuse installation method?
The size of this type of fuse is compact, making it easy to install. There are various installation methods available for your preference, including ferrule, axial bolt, surface mount, and flush bolt-on.
You can choose the most suitable installation method based on the requirements of your electrical system.
Ferrule
Surface Mount
Axial Bolt-on-1
Axial Bolt-on-2
Flush Bolt-on
What factors should consider when choosing the right cartridge ceramic fuse?
The selection of fuses depends on many factors, including current, voltage, breaking capacity, installation size requirements, etc. Here are some suggestions to help you choose the right fuse for your specific application.
1. Fuse Current and Voltage Rating
Fuse current and voltage rating is a crucial adjective, once you determine them, you are on the right track. However, when at room temperature, you need to consider temperature derating at 25%.
It means if your circuit is 10 amp, you need to use 12.5 amp at 25˚C. The fuse rated voltage can be higher than the circuit voltage, but not lower.
2. Breaking Capacity
Breaking capacity is the ability of a fuse to safely interrupt a circuit in the event of a fault. Make sure the breaking capacity of the selected fuse meets or exceeds the requirements for transient overcurrents that may occur in the circuit.
3. Correct Mounting Dimensions
Correct mounting dimensions ensure that the fuse functions effectively in the circuit and can fit within given space and layout constraints.
Make sure the fuse you choose is the right size for the space available in your electrical system, including length, diameter, etc.
What’s the difference between aR, gR, gG, and gPV?
They are all IEC international standards that represent different types of fuses, which relate to the way they work.
aR
aR class type fuse usually provides partial protection for semiconductors. It could only supply short circuit protection.
gR
gR fuse can provide full range protection with both short circuit and overload protection for semiconductors.
gG
gG is a general purpose fuse for short circuit and overload protection, suitable for general industrial and commercial electrical systems, providing a full range of cables and wires protection. Their acting speed is no faster than other fuses.
gPV
gPV stands for a fuse for photovoltaic (PV) systems that are specially designed to meet the requirements of solar systems, including protection of direct current. It is mainly used in solar photovoltaic systems to protect photovoltaic modules and related electrical equipment.
How to distinguish the breaking capacity and interrupting rating?
Breaking capacity and interrupting rating are somewhat similar, and are often used interchangeably.
Breaking capacity refers to the maximum current that a fuse must be able to safely break the circuit in the event of a short circuit without damaging the circuit and the surrounding environment.
The interrupting rating is the maximum available current at a rated voltage that the fuse can safely open without rupture under standard test conditions.
The interrupting rating of the fuse must be greater than or equal to the short-circuit current available in the circuit.
Why does my cartridge ceramic fuse keep blowing?
First, unplug all from the circuit. If it works, either there’s something wrong with one of the things you unplugged, or there’s too much plugged into the circuit.
If your fuse still keeps blowing after you replace into a new one and unplugging everything, the problem might be on somewhere of your circuit itself, you could call an electrician to carefully check your circuit and fix the faulty circuit.
Applications of Cartridge Ceramic Fuse
EV/HEV
The battery system and motor used in electric vehicles usually use DC power supply. The ferrule-type fuse can be used to protect the electrical system of electric vehicles and prevent safety issues caused by circuit faults. This high-speed fuse is a good choice to protect the battery under short circuit fault conditions with excellent current limiting effect.
Battery pack
The ferrule-type fuse is also used in battery packs to prevent the current in the battery pack from exceeding the safety rating. If overload current or short-circuit current in circuit, it protects the battery and related electrical equipment by disconnecting the circuit to prevent current overload. dangers and damages.
Photovoltaic systems
HIITIO ferrule-type solar fuse is designed to integrate into an in-line assembly within a wire harness. The fuse provides photovoltaic (PV) protection that meets UL 248-19 for photovoltaic applications. This can be electrically insulated by either over-molding or using heat shrink. Same time meets IEC 60269-6 (2010) electrical performance and installation requirements.
It is important to use gPV fuses to protect photovoltaic panels and conductors from reverse over-current conditions. Our gPV series fuses have the ability to interrupt very low overcurrents at full voltage.
Inverter system
The inverter converts DC power into AC power. In the inverter system, ferrule-type fuses are usually used to protect the DC side circuit of the inverter to ensure that the system can quickly cut off the current when a short circuit or overload occurs, preventing damage to the equipment or causing a security problem.
Industrial DC power supply system
In industrial automation and control systems, DC power supplies are often used to drive motors, control solenoid valves and other equipment, the ferrule-type DC fuses can protect these key components and ensure the stable operation of the system.
DC Relay protection
The main function of ferrule-type fuse is to quickly cut off the circuit when overcurrent occurs in the circuit. Relays are typically used to control electrical current, but under certain circumstances, a current overload can occur, such as a fault or short circuit. Fuses can quickly interrupt the circuit in these situations and prevent excessive current from damaging relays and other equipment.
