Fuse 19 mm 30 A, black, UL94V-0 mounting type

Cartridge fuse with a 19 mm length and a 30 A rated current in a black UL94V-0 rated housing designed to protect electrical circuits from overcurrent. The compact 19 mm form factor makes this fuse suitable for tight installations in automotive, industrial and electronic equipment where space is limited. The UL94V-0 flame-retardant enclosure reduces flammability risk and the straightforward cartridge design allows fast inspection and replacement during maintenance.

Advantages

The 19 mm cartridge fuse delivers consistent overcurrent protection at a 30 A rating while occupying minimal space. Its black housing meets UL94V-0 flammability standards, providing enhanced safety in environments where reduced ignition risk is required. The cartridge format enables quick removal and replacement without special tools, and the standardized dimensions simplify integration into existing fuse holders and assemblies.

Suitable for

• Automotive electrical circuits and accessories
• Industrial control panels with compact fuse holders
• Electronic devices and appliances requiring 19 mm fuses
• Maintenance and repair kits for field service

Key specifications

• Rated current: 30 A
• Physical length: 19 mm cartridge style
• Housing color: black
• Flammability rating: UL94V-0 (flame-retardant material)
• Mounting type: cartridge/fuse holder compatible

How to use

Turn off power to the circuit before attempting to remove or install the fuse. Verify the fuse holder is compatible with a 19 mm cartridge fuse and that the circuit requires a 30 A rated protection element. Insert the fuse into the holder until it seats securely; ensure proper polarity or orientation only if the application requires it. After installation, restore power and check the circuit for normal operation. Replace a blown fuse only with one of the same rated current and physical dimensions.

Usage recommendations

Use this 19 mm 30 A cartridge fuse in applications where the compact size and UL94V-0 flame-retardant housing are required. Avoid replacing with a fuse of a higher rating, as that can compromise circuit protection. Store spare fuses in a dry, dust-free environment and inspect fuse holders for corrosion or mechanical wear before installation.
