Glass Fuse 1.25A 250V T6x30mm
Product Description
Ensure the safety of your high-power electronic devices with our premium 1.25A 250V Glass Tube Fuses. These 6x30mm (1/4″ x 1-1/4″) fuses are larger and more robust than standard electronics fuses, designed specifically for heavy-duty protection in industrial equipment, power tools, and older automotive circuits.
As a T-type (Time-Delay/Slow-Blow) fuse, this component is built to handle momentary “inrush” currents without blowing. This makes it ideal for devices with motors or transformers that require a quick surge of power to start, while still providing 100% protection against sustained overloads and short circuits.
Key Features:
Heavy-Duty Protection: The 6x30mm size is designed for better heat dissipation and higher breaking capacity in demanding environments.
Slow-Blow (T1.25A) Technology: Engineered to survive brief current spikes, preventing “nuisance blowing” in high-torque machinery.
Universal Industrial Fit: Compatible with standard 6.3mm (1/4 inch) fuse holders, panel-mount fuse blocks, and screw-cap holders.
High-Visibility Inspection: The reinforced glass body allows you to instantly verify the condition of the internal fuse element.
Safety Certified: Built to handle up to 250V, making it suitable for both AC and DC applications.

Common Applications
Industrial Power Supplies: Used in heavy-duty control panels.
Power Tools: Ideal for drills, saws, and grinders that have high startup current.
Consumer Electronics: Found in older amplifiers, large printers, and CRT monitors.
Automotive/Marine: Used in specific 12V/24V/250V fused panels.
Pro Tip: While they look similar, a 6x30mm fuse will not fit in a 5x20mm holder. Always measure your fuse holder dimensions before ordering to ensure a perfect fit.
