A fuse holder is a base used for installing fuses, and the following are some of its important
parameters:
Electrical parameters
rated voltage
The maximum voltage that the fuse holder can withstand under normal operating conditions. If
the actual voltage used exceeds the rated voltage, it may cause breakdown, flashover, and other
phenomena inside the fuse holder, leading to safety accidents.
rated current
The maximum current value that indicates the long-term stable operation of the fuse holder. When the
current passing through the fuse holder exceeds the rated current, the fuse holder may be damaged due
to overheating, affecting its normal use and safety.
breaking capacity
Also known as short-circuit breaking capability, it refers to the maximum short-circuit current
value at which a fuse holder can safely cut off a circuit in the event of a short circuit or other fault without
the risk of arcing, explosion, or other hazards.
The higher the breaking capacity, the more reliable the protection of circuits and equipment in
the event of a short circuit. For example, in some industrial circuits where large short-circuit currents may
occur, it is necessary to choose fuse holders with higher breaking capacity.
mechanical parameters
Size specifications
Including the external dimensions of the fuse holder, installation hole dimensions, etc. Appropriate
size specifications are crucial for the installation and use of fuse holders.
Pin spacing
Pin spacing can affect the connection and wiring with other circuit components. If the pin
spacing does not meet the requirements, it may lead to difficulty in connection or unreasonable wiring,
affecting the performance and stability of the circuit.
Material and structural strength
Fuse holders are usually made of materials such as plastic and ceramics, and the mechanical strength,
heat resistance, insulation performance, etc. of different materials may vary.
environmental parameters
Working temperature range
The temperature range within which the fuse holder can operate normally. If the operating
temperature exceeds this range, it may affect the performance and lifespan of the fuse holder.
Humidity and protection level
Humidity can affect the insulation performance of the fuse holder, and excessive humidity may cause
moisture inside the fuse holder, leading to faults such as short circuits. The protection level indicates the
ability of the fuse holder to protect against external factors such as dust and water.
