Product Description The 40A Automotive Blade Fuse is a standard-sized safety component widely used in vehicle electrical systems to protect wiring and accessories from overcurrent. Designed for high-current applications, this fuse features a transparent housing for quick visual inspection and a robust zinc alloy element for precise protection. Whether you are replacing a blown car fuse or building high-power robotics, these fuses offer a compact and reliable solution for DC power management.

Key Features

  • High Current Handling: Rated for 40A, making it suitable for heavy-duty automotive circuits like cooling fans or amplifiers.

  • Standard ATO/ATC Fit: Compatible with all standard automotive fuse blocks, holders, and panels.

  • Visual Diagnostic: Transparent thermoplastic body allows you to instantly see if the fuse link is broken.

  • Colour-Coded Housing: Industry-standard orange colour for easy identification of the amperage rating.

  • RoHS Compliant: Manufactured using environmentally friendly materials and lead-free processes.

Technical Details

  • Voltage Max: Rated for DC systems up to 32V, covering standard 12V and 24V vehicle architectures.

  • Interrupting Rating: Designed to safely break the circuit during severe short-circuit events without melting the housing.

  • Blade Material: High-conductivity Zinc Alloy blades for low-resistance electrical contact.

  • Housing Material: Heat-resistant, self-extinguishing plastic to prevent fire hazards during overload.

  • Operating Temperature: Stable performance in harsh automotive environments ranging from -40°C to +125°C.

  • Insertion/Extraction: Designed for smooth installation and removal using standard fuse puller tools.

  • Corrosion Resistance: Blade coating prevents oxidation, ensuring long-term reliability in humid conditions.

  • Vibration Resistance: Secure friction-fit blades stay seated during heavy mechanical shocks and vehicle movement.

  • Fast-Acting Trip: Interrupts current rapidly to protect delicate high-power electronics and wiring harnesses.

  • Clear Amperage Stamp: The 40A rating is clearly embossed on the top of the fuse body for permanent identification.

  • Low Voltage Drop: Engineered for minimal power loss, ensuring maximum energy reaches your load.

  • Versatile Application: Ideal for car audio, lighting rigs, winches, and high-current robotics power distribution.

Prototyping and Engineering Tips from Robogears

  • 18650 Battery Banks: When building 18650 parallel packs for electric cycles or large robots, use this 40A fuse on the main positive lead to protect against catastrophic shorts.

  • High-Power Motor Drivers: Perfect for protecting the BTS7960 43A Motor Driver or high-current ESC (Electronic Speed Controllers).

  • 9V Battery Note: This 40A fuse is not suitable for 9V batteries, as they cannot provide enough current to blow it; use a 1A or 2A fuse instead.

  • Mounting Tip: Use a dedicated Blade Fuse Holder with thick 10 AWG or 12 AWG wire to prevent the holder itself from melting at high current.

  • Related Products: We recommend pairing these with our Automotive Fuse Holders and Heavy-Duty Silicone Wire.

Package Includes

  • 1 x 40A Automotive Blade Fuse (Standard Size).
