Frequently Asked Questions

We have compiled some common questions from our clients. If your question isn’t included here, our customer service is always available to help. We’d love to talk with you.

Q1: What is a blade fuse and what does it do?

A blade fuse is a standard type of electrical fuse used in modern vehicles. Its primary job is to protect the wiring and electrical equipment in a circuit. It contains a metal element designed to melt and break the circuit if the current exceeds a safe level, preventing damage and potential fire.

Q2: What do the different blade fuse colors mean?

The color of the fuse indicates its amperage rating. This is a standardized industry code:
Yellow: 20A
Clear/White: 25A
Green: 30A
Blue: 15A
Red: 10A
Pink: 5A (Common in Mini size)
Purple: 3A
Orange: 5A (Common in ATO size)
Brown: 7.5A
Tan: 25A (Less common, sometimes used for 25A Mini)

Q3: What are the different sizes of blade fuses?

The main sizes are:

  • Micro2 & Micro3: Smallest, for very new vehicles with limited space.

  • Low-Profile Mini: Shorter than standard Mini fuses.

  • Mini (APM/ATM): The most common size in modern cars.

  • Standard (ATO/ATC): The classic size found in most vehicles for decades.

  • Maxi (APX): The largest size, used for very high-current circuits.

Q4: What causes a car fuse to blow repeatedly?

A blown fuse is a symptom of an underlying problem. If a new fuse blows immediately or repeatedly, it indicates:

  • short circuit in the wiring (e.g., damaged insulation).

  • malfunctioning component (e.g., a motor seizing, like in a power window or blower fan).

  • Overloading the circuit by adding accessories that draw more power than the circuit was designed for.

Q5: Can I use a higher amp fuse if I don't have the correct one?

No, absolutely not. This is extremely dangerous. A fuse is a safety device calibrated to a specific wire gauge. Using a higher amp fuse (e.g., a 25A instead of a 15A) allows excessive current to flow, which can overheat the wiring, melt insulation, and start an electrical fire. Always replace a fuse with one of the exact same amperage rating.

Q6: Can I repair a blown fuse?

No. Blade fuses are sealed, single-use units. They cannot and should not be repaired. Attempting to bypass a blown fuse with foil, wire, or any other metal object completely defeats its safety purpose and creates a severe fire hazard. Always replace it with a new, high-quality fuse.

Q7: What is the difference between a "fast-acting" and a "slow-blow" fuse? •

  • Fast-Acting (Standard): These blow almost instantly when their current rating is exceeded. They are used to protect sensitive electronic devices (e.g., stereos, ECUs, display screens).

  • Slow-Blow (Time-Delay): These are designed to tolerate a temporary current surge (like when a motor starts) without blowing, but will blow under a sustained overload. They are used for circuits with motors (e.g., power windows, sunroofs, fuel pumps).

Q8: How can I tell if a TONFUL fuse is high quality? •

High-quality fuses, like those from TONFUL, have distinct features:

  • Clear, Laser-Etched Markings: The amperage rating won’t rub off over time.

  • Precise Dimensions: They fit snugly and securely in the fuse box without being loose or too tight.

  • Robust Housing: Made from high-grade plastic that is heat-resistant and durable.

  • Quality Internal Element: Made from precise materials to ensure it reacts at the exact specified current.

  • Compliance Marks: Look for marks like CERoHS, and compliance with international standards (ISO 9001), which indicate rigorous testing.

Q9: Does TONFUL offer custom or OEM services for blade fuses?

Yes. As a professional manufacturer, TONFUL specializes in OEM and ODM services. We can provide custom amperage ratings, branding, packaging (bulk, blister packs, clamshells), and even tailored performance characteristics to meet specific client requirements.
