Kentech FB800MA Fast-Blow Glass Fuse (5 x 20mm, 800mA)

• Precision fast-acting (fast-blow) miniature glass tube fuse engineered to protect delicate low-power circuits, pro-audio signal processing gear, and sensitive electronic instruments against overcurrent damage.
• Features a highly sensitive fast-blow profile that rapidly interrupts the circuit upon detecting minor electrical overloads, power surges, or short circuits.
• Manufactured in the standard European 5 x 20 mm footprint with nickel-plated brass end caps for high conductivity and long-term oxidation resistance.
• Clear, transparent glass cylinder casing allows for fast, visual inspection to easily confirm whether the internal fuse wire is intact or blown.
• Ideal replacement component for active speaker preamps, mixer power boards, measuring instruments, and low-current circuit boards.

Features

• Sensitive Low-Current Protection: Opens rapidly when current levels exceed its 800mA (0.8A) rating to safeguard fragile downstream electronics.
• Transparent Glass Body: Clear casing enables instant visual confirmation of fuse integrity without requiring diagnostic tools.
• Corrosion-Resistant End Caps: High-grade nickel-plated brass caps maintain consistent, low-resistance electrical contact in fuse blocks and clips.
• Standard 5 x 20 mm Size: Compact European footprint compatible with standard panel-mount, inline, and PCB fuse holders.
• Broad Compatibility: Essential maintenance part for pro-audio equipment repair, bench testing, power supply boards, and delicate electronics.
