Fuse Holder and Fuse Carrier

A fuse holder is mounted within the instrumentation and is intended to carry the fuse. Fuse holders will hold each North yankee and international sized fuses. this is often supported that fuse carrier is being employed. HINEW offers panel-mount fuse holders、 automotive fuse holders、pcb fuse holders and wire harness fuse.

Fuse Blocks, Fuse Holders and Fuse Accessories

what is a fuse holder？

Fuse holders are devices for containing, protecting and mounting fuses. Fuse holders come in two basic types, open or fully enclosed. Open fuse holder types are fuse clips, fuse blocks, socket and plug-on cap varieties. The fully enclosed variety may use a fuse carrier that is inserted into a holder or have other means to fully enclose the fuse.

Sizes and Specifications

Standard fuse sizes range from ¼” diameter, 5/8” length (1AG) to ¼” diameter 1” length (8AG), to 5mm x 20 mm, pico fuses and automotive blade. "Automobile Glass" fuses use the term "AG" in the fuse size designation. Bakelite fiber, ceramic or other similar material fuses use the term "AB" instead of "AG" in the size designation, but retain the dimensions of the "AG" types. Automotive blade fuse sizes differ from glass tube sizes due to the shape of the fuse. Important performance specifications to consider when searching for fuse holders include normal operating current, rated operating voltage, and power dissipation capacity. The maximum power dissipation (self-heating) of the fuse used with the fuse holder. Also called the Rated Power Acceptance. The minimum conducting path or conductor cross-sectional area of the conductor connected to the fuse holder should also be considered.

Mounting

Mounting choices for fuse holders include fuse block, fuse clip, panel mount, PC mount, snap mount, and in-line mount. Important environmental parameters to consider when specifying fuse holders include operating temperature.

how to install fuse holder on power wire？

1、Disconnect the electrical power source to the device.

　　2、Cut the positive--or "hot"--wire as near to the power source as possible using the wire cutting pliers.

　　3、Strip 1/4-inch off each end of the separated wires with the wire stripping pliers.

　　4、Strip 1/4-inch off each of the wires on the ends of the fuse holder. Be sure to hold each wire firm when stripping to avoid stress on the fuse holder’s internal connections.

　　5、Twist the end of the wire from the power source in either direction creating a helical, or spiral, form. This helps to make the stripped ends firm for connecting.

　　6、Insert the twisted wire from the power source into one end of the butt-splice crimp connector and crimp tightly with the crimping pliers.

　　7、Insert the twisted wire from the power source into one end of the butt-splice crimp connector and crimp tightly with the crimping pliers.

　　8、Twist the end of either side of the fuse holder's leads and insert it into the other end of the butt-splice connector. Crimp down tightly on the connector with the pliers.

　　9、Check both ends of the butt-splice for a firm connection.

　　10、Twist the wire leading to the electrical device to make it firm and insert it into a butt-splice connector. Crimp down tightly on the connector with the crimping pliers.

　　11、Twist the wire leading from the other half of the fuse holder and insert it into the other end of the butt-splice attached to the wire leading to the device. Crimp down tightly on the connector with the crimping pliers.

　　12、Insert the properly rated amperage fuse into the fuse holder. Connect the two halves by compressing them together and then twisting to lock into place.

　　13、Restore the electrical power to the device.

how to open a fuse holder？

In a consumer unit

Switch off the mains power, then check each fuse to see which one has blown. If your unit has cartridge-type fuses, you will need to buy a new one from an electrical store. If it has rewirable fuses, remove the old fuse wire, making a note of how it is positioned. Replace with a new wire of the correct amperage, winding it round the screws at both ends.

In a fused connection unit

Ensure that the unit is switched off, then, using the tip of a slot‑head screwdriver, gently open the fuse holder: this is found next to the switch – on ovens etc this is usually on the wall to the side of the appliance. Replace the old fuse with a ceramic fuse of the same amperage.

In a plug

If there is a fuse holder on the bottom of the plug, gently open it using the tip of a slot-head screwdriver. If not, unscrew the large central screw on the base of the plug and open it up. Remove the fuse using a screwdriver, as before. Replace with one of the right amperage for the appliance. Replace the plug cover and screw tight.

Warning

If the fuse blows again immediately, it is likely there is a problem. Consult an electrician.

what causes a fuse holder to melt？

1、Wire strands left outside the fuse holder

2、Too much current for the gauge of wire

3、Location – Ideally the fuse holder should be 1 ft away from the battery and not able to touch anything hot.
