ATL Low-Profile Mini Blade Fuse Series (5A–30A, 32V DC)
Overview
The ATL series is a low-profile mini blade fuse designed for automotive, aftermarket, and low-voltage DC circuit protection. With rated currents from 5A to 30A at 32V DC and a 1000A interrupt rating, it protects wiring harnesses, accessories, and control modules in passenger vehicles, light trucks, and agricultural equipment.
The compact 9.0 × 3.8 × 15.4 mm body fits standard mini fuse blocks and panels, while the nylon PA66 housing withstands under-hood temperatures and chemical exposure. Each amp rating has a distinct body color for quick visual identification during field service.

FAQ
Q1: What is the difference between ATL and ATC blade fuses?
ATL is the low-profile mini blade fuse (9.0 × 3.8 mm body), while ATC is the standard blade fuse (19.1 mm body). ATL is smaller and used in modern compact vehicle fuse panels where space is limited.
Q2: What amp ratings are available in the ATL series?
The ATL series covers 5A (tan), 7.5A (brown), 10A (red), 15A (blue), 20A (yellow), 25A (natural/white), and 30A (green), all rated at 32V DC.
Q3: What is the interrupt rating of the ATL blade fuse?
1000A at 32V DC, which is sufficient for typical automotive short-circuit protection in passenger vehicles.
Q4: Can the ATL fuse be used in 12V and 24V systems?
Yes, the 32V DC rating covers both 12V and 24V automotive electrical systems.
Q5: What is the operating temperature range?
Silver-plated versions operate from -40°C to +125°C. Tin-plated versions operate from -40°C to +105°C. Choose silver plated for under-hood installations with higher ambient temperatures.
