Littelfuse 0327020 Automotive Fuse 20 Amp 32 Vdc MICRO2

Product Description

The LITTELFUSE 0327020 is a MICRO2 sub-mini blade-style automotive fuse rated at 20 amps and 32 volts DC. Designed for low-voltage vehicle circuit protection, it fits into compact fuse block positions where standard-size blades will not seat. The housing is molded from PA66 thermoplastic and the terminals are zinc alloy with a silver-plated finish, providing reliable conductivity and corrosion resistance in underhood and interior electrical environments. This fuse is sold in a package quantity of one with a minimum order quantity of ten units. It is installed by automotive electricians and fleet service technicians working on light-duty vehicle wiring systems.

The 0327020 is suited for use in passenger vehicles, light trucks, and commercial vehicles that use MICRO2 sub-mini blade fuse holders. Typical applications include infotainment circuits, accessory outputs, low-current control circuits, and other vehicle systems where space-constrained fuse block designs require a sub-mini form factor. The yellow color coding indicates the 20-amp rating, consistent with SAE and ISO blade fuse color conventions. This part meets RoHS requirements and is certified to SAE 2741 and ISO 8820-12:2020 standards.

Key Features

• Compliant with RoHS, SAE 2741, and ISO 8820-12:2020

Compatibility

Designed for use in vehicle fuse blocks and holders that accept MICRO2 sub-mini blade-style fuses rated for 32 volts DC automotive circuits.

Installation Notes

Installation is performed by automotive electricians or qualified vehicle service technicians. Disconnect the vehicle battery before servicing any fuse block to prevent accidental circuit energization. Verify the replacement fuse matches the amperage rating of the original to avoid circuit damage or fire hazard. Never substitute a higher-amperage fuse to bypass a nuisance-trip condition without first diagnosing the underlying fault.
