What is cylindrical fuse link？
A cylindrical fuse is an overcurrent protection element with a cylindrical structure. Its core consists of a fuse wire (fusible element), an insulating shell (ceramic/glass material), and leads or terminals. It is widely used in electrical circuits.
Its working principle: When an overload or short circuit occurs in the circuit, the excessive current causes the fuse wire to heat up and melt, quickly cutting off the circuit and preventing damage to electrical equipment and wires due to overheating, thus providing safety protection.
Cylindrical Fuse Link Key features:
Compact structure, easy installation (compatible with fuse holders or direct wiring);
Sensitive operation, fast protection response;
Diverse materials (fuses are mostly lead-tin alloy or copper alloy, housing is ceramic/glass);
Wide range of specifications (rated current and voltage adaptable to different circuit requirements).
How to Choose the Right Cylindrical Fuse Link？
Choosing the right cylindrical fuse requires matching the core parameters of your circuit. Follow these key steps to ensure accurate and safe protection:
Confirm Rated Voltage: The fuse's rated voltage must be ≥ the circuit's operating voltage (e.g., select a ≥220V fuse for a 220V circuit). Otherwise, arcing may occur upon fuse blowing, posing a danger.
Match Rated Current: Select according to load type: For resistive loads (e.g., resistors), select a rated current ≈ 1.1 times the operating current; for inductive/capacitive loads (e.g., motors), select 1.5–2.5 times the operating current to avoid accidental fuse blowing due to normal starting current.
Check Size Specifications: Cylindrical fuses have fixed outer diameter and length standards (e.g., 5×20mm, 6×30mm). These must perfectly match the fuse holder size to prevent loose installation.
Select Fusing Characteristics: Fast-blow (Type F): Suitable for precision electronic equipment, it blows instantly upon short circuit, protecting sensitive components.
Select Fusing Characteristics: Delayed fuse (T type): Withstands short-time starting current and is suitable for circuits with impact loads such as motors and transformers.
Cylindrical Fuse Link Application
Cylindrical fuse link are widely used in low-voltage power systems requiring short-circuit/overload protection, with core applications covering the following areas:
Home appliances: air conditioners, refrigerators, washing machines, microwave ovens, and other common household appliances.
Industrial electrical equipment: machine tools, water pumps, fans, frequency converters, and other general machinery, as well as wiring protection inside distribution boxes and control cabinets.
New energy: photovoltaic inverters, energy storage battery packs, electric vehicle charging piles, and other equipment that ensures the circuit safety of new energy equipment.
