Automotive mini micro3 blade fuses are compact 3-pin fast-acting blade fuses, specially engineered for dense, space-saving vehicle fuse boxes. This Micro3 blade fuse design protects two independent circuits with one single fuse, widely used for passenger cars, SUVs and motorcycles with limited wiring compartment space. Rated for 32V DC automotive electrical systems, it delivers stable overcurrent and short-circuit protection.
Key Features
- Unique 3-pin Micro3 blade footprint, dual-circuit protection in one fuse
- Fast blow characteristic, rapid response for short-circuit fault
- Color-coded housing for quick ampere rating identification
- High interrupting capacity: 1000A @ 32V DC
- PA66 flame retardant housing, zinc alloy tin-plated terminals
- RoHS compliant, lead-free construction for global automotive aftermarket export
- Compact outline, perfect for high-density automotive fuse panels

FAQ
Q: What is Micro3 blade fuse?
A: Micro3 blade fuse is a special 3-pin mini automotive blade fuse. One single fuse provides protection for two separate circuits, designed for space-limited compact car fuse panels.
Q: What voltage is Micro3 blade fuse rated for?
A: Standard rating is 32V DC, it is only suitable for automotive DC circuits, not for AC power circuits.
Q: What amp ratings are available for this Micro3 fuse?
A: Available ratings: 5A,7.5A,10A,15A with color coded housing for easy identification.
Q: Do I need to consider temperature derating for Micro3 fuses?
A: Yes. Higher ambient temperature will reduce continuous carrying capacity. It is recommended to derate current when installed inside high-temperature engine compartment fuse boxes.
Q: Are these mini Micro3 blade fuses RoHS compliant?
A: Yes, all automotive mini micro3 blade fuses are RoHS compliant and lead-free, suitable for export markets.
Q: Can you support OEM custom marking and bulk supply?
A: Yes, we provide bulk wholesale, OEM laser marking and custom packaging service. Contact sales team for quotation.
