Product Description
The CEI 4A Fast-Acting Glass Fuse is a high-reliability safety component designed to protect medium-load electronic circuits. Measuring the standard 5x20mm, this "small" format fuse is ideal for protecting power adapters, charger circuits, and small motorised appliances. With a 4-Amp rating, it acts as a sacrificial link that interrupts power during an overload, preventing expensive damage to your main controller boards and sensitive semiconductors.
Key Features
Rapid Fault Interruption: Designed to blow instantly when current exceeds 4A, shielding downstream components from spikes.
Clear Diagnostic Body: Transparent glass housing allows for a quick visual check to see if the internal filament is broken.
Anti-Oxidant Caps: Features nickel-plated brass caps that ensure low contact resistance and prevent corrosion over time.
Universal 5x20mm Size: Compatible with all standard "small" fuse holders, including PCB clips and panel-mount housings.
Economical Bulk Pack: Comes in a pack of 20, providing a long-term supply for maintenance and laboratory prototyping.
