3.15A Slow-Blow Glass Cartridge Fuse

Overview

The 3.15A Slow-Blow Glass Cartridge Fuse is a reliable overcurrent protection component designed for electronic devices that experience momentary current surges. This time-delay fuse allows short, harmless inrush currents while protecting circuits from sustained overloads and short circuits. The transparent glass body provides visible confirmation of fuse status, and metal end caps deliver strong electrical contact in standard fuse holders.

Key Features

• 3.15A current rating suitable for medium-power electronics
• Slow-blow (time-delay) characteristic to withstand brief inrush spikes without blowing
• Glass cartridge body for easy visual inspection and quick fault diagnosis
• Metal end caps for secure mechanical and electrical connection
• Standard size fits common fuse holders and inline fuse clips
• Provides dependable overcurrent and short-circuit protection

Technical Benefits

• Prevents unnecessary downtime by tolerating harmless startup currents from motors and transformers
• Protects sensitive electronics from overheating and damage caused by sustained overloads
• Simple replacement and visual verification reduce service time

Typical Applications

• AC adapters and power supplies
• Audio amplifiers, receivers and speakers
• Chargers, small appliances and consumer electronics
• Test equipment and laboratory instrumentation
• DIY electronics projects and hobbyist builds
• Motor-driven devices that generate inrush current at startup

Specifications

• Current rating: 3.15A
• Fuse type: Slow-blow (time-delay)
• Body: Transparent glass cartridge for visual inspection
• End caps: Metal for reliable contact
• Mounting: Standard cartridge size compatible with common holders and clips

Installation and Compatibility

Always replace a blown fuse with the same rating and type. Confirm the fuse holder dimensions and ratings before installation. The 3.15A slow-blow glass cartridge fuse is compatible with most standard in-line and panel-mounted fuse holders used in power supplies, adapters and consumer electronics.

Safety and Handling

• Turn power off before replacing the fuse to avoid electric shock.
• Do not substitute with a higher rated fuse; this defeats protection and risks device damage or fire.
• Inspect the glass cartridge for visible signs of a blown fuse (broken filament or discoloration).
