Fuses

We offer a wide range of fuses to suit various applications:

• Blade Fuses: Commonly used in automotive and low-voltage circuits.
• Cartridge Fuses: Designed for higher current applications, often found in industrial settings.
• Class J Fuses: Provide protection in industrial circuits, offering high interrupting ratings.
• Class T Fuses: Fast-acting fuses used in motor circuits and other critical applications.
• Class L Fuses: Used in high-current applications, providing high interrupting ratings.
• Class CC Fuses: Compact fuses offering high interrupting ratings for branch circuits.
• Thermal Fuses: Designed to protect appliances from overheating by disconnecting the circuit when a certain temperature is exceeded.
• Time Delay Fuses: Allow temporary overloads without blowing, suitable for circuits with inrush currents.
• HVAC Fuses: Specifically designed for heating, ventilation, and air conditioning systems.
• Inline Fuses: Integrated into wires, commonly used in automotive and low-voltage applications.
• Plug Fuses: Screw-in fuses typically used in older electrical panels.
• Dryer Fuses: Specialized fuses designed for clothes dryer circuits.
• 5 Amp, 20 Amp, 25 Amp, 30 Amp Fuses: Available in various types to match specific circuit requirements.
• Bussmann Fuses: A trusted brand offering a variety of fuse types for different applications.

Testing a fuse is straightforward and can be done using a multimeter:

1. Turn off the power to the circuit containing the fuse.
2. Remove the fuse from its holder.
3. Set your multimeter to the continuity or resistance mode.
4. Place the multimeter probes on each end of the fuse.
5. Interpret the reading:

• If the multimeter beeps or shows a low resistance value (close to 0 ohms), the fuse is good.
• If there is no beep or the resistance is infinite, the fuse is blown and needs replacement.

Both fuses and circuit breakers serve to protect electrical circuits from overloads and short circuits:

• Fuse: A one-time protection device that melts when excessive current flows through it, breaking the circuit. It must be replaced after activation.
• Circuit Breaker: A resettable device that trips to disconnect the circuit when an overload or short circuit occurs. It can be reset and reused without replacement.

Fuses are generally more compact and cost-effective, while circuit breakers offer the convenience of resetting without replacement.

When selecting a fuse, consider the following factors:

• Current Rating: Ensure the fuse's amperage matches the circuit's requirements.
• Voltage Rating: The fuse's voltage rating should equal or exceed the circuit's voltage.
• Type of Fuse: Choose between blade, cartridge, class J, class T, etc., based on the application.
• Time-Current Characteristics: Decide between fast-acting, time-delay, or slow-blow fuses depending on the circuit's nature.
• Physical Size and Mounting Type: Ensure the fuse fits the holder and is compatible with the installation.

If you're uncertain, consult with a professional electrician or refer to the equipment's manual for fuse specifications.
