12V 15A Blade Fuse is a small automotive fuse designed to protect a 12-volt DC electrical circuit from carrying more than 15 amperes (15A) of current. If the current exceeds 15A for a sufficient period, the fuse element melts and opens the circuit, preventing damage to wiring and equipment.
Fuse Type:Blade Fuse (ATO, ATC, Mini, or Micro depending on model)
Rated Voltage:12V DC (typically rated up to 32V DC)
Rated Current:15A
Function:Overcurrent and short-circuit protection
Fuse Element Material:Zinc Alloy
Housing Material:Transparent Thermoplastic
Mounting:Plug-in blade terminals
Operating Temperature:Typically -40°C to +125°C
How It Works
Normal current: ≤ 15A → Fuse remains intact.
Excessive current: > 15A → Fuse element heats up and melts.
Circuit opens, protecting connected devices and wiring.
Typical Applications
LED lighting circuits
Dashboard electronics
Sensors and control modules
Small motors
Automotive accessories
DIY electronics projects using 12V power
