Sierra FS79190 AGC Glass Tube Fuse 20 Amp 5-Pack Marine Electrical

The Sierra FS79190 is a pack of five AGC-style fast-acting glass tube fuses rated at 20 Amps and 32 Volts, designed for use in marine electrical systems. The standard AGC form factor measures 1/4" x 1-1/4", making these fuses compatible with the vast majority of AGC-style fuse holders and fuse panels found on boats, watercraft, and other powersports equipment.

Key Features:

• Fast-acting glass tube fuse construction for precise overcurrent protection
• 20 Amp rating at 32V DC — ideal for marine-grade electrical circuits
• Standard AGC form factor: 1/4" diameter x 1-1/4" length
• Pack of 5 replacement fuses for ongoing maintenance and onboard spares
• Compatible with AGC-style inline fuse holders and multi-circuit fuse panels
• Suitable for protecting electronics, lighting, bilge pumps, and accessory circuits

Keeping a supply of spare fuses onboard is an essential part of marine electrical preparedness. The Sierra FS79190 ensures you have the correct 20 Amp AGC replacement on hand whenever a fuse needs to be swapped out, minimizing downtime on the water. Always replace fuses with an identical amp rating to maintain proper circuit protection.
