Glass Fuse Holder with 2A Fuse (Mains Protection)

The Glass Fuse Holder with 2A Fuse is a practical circuit-protection accessory for adding a replaceable fuse to electronic equipment. It is designed for the common 5 mm x 20 mm miniature glass cartridge fuse format, widely used in power supplies, adapters, chargers, instrumentation, household electronics and educational projects. The included 2A fuse is rated up to 250V AC, making it suitable for many mains-input protection layouts when used within the correct circuit design and safety practices. A fuse protects a circuit by opening when current exceeds its rated limit for a defined period, helping reduce damage caused by overloads, wiring faults or short circuits. The holder provides a secure mechanical contact for the fuse and allows quick replacement after a fault, instead of soldering a new fuse directly onto the board. This is especially useful for prototypes, repair jobs and equipment that may need service access. This product is best used on the input side of small power supplies, AC-to-DC converter projects, control panels, test fixtures, LED drivers, amplifier boards and general electronics kits. The 5 x 20 mm glass fuse size is easy to source, so you can replace the supplied 2A fuse with another compatible current rating if your design requires it, provided the voltage, breaking capacity and safety approvals match your application. The holder is intended for PCB mounting and uses two electrical terminals for connection in series with the live or positive supply line. For mains circuits, always maintain proper creepage/clearance, insulation, enclosure safety and earthing as applicable. Installation should be performed only by a competent person. Package includes one 5 x 20 mm glass fuse holder and one 2A 250V glass fuse.
