SIBA 5mm x 20mm Ceramic Time Delay Fuse - 1A

The SIBA 5mm x 20mm Ceramic Time Delay Fuse is a high-quality, industrial-grade component designed to provide reliable circuit protection. Engineered for safety and durability, this fuse utilises a ceramic body for superior heat resistance and stability, ensuring consistent performance even under demanding electrical conditions. Its time-delay (slow-blow) characteristic is a critical feature, allowing it to withstand harmless, temporary current surges—such as those caused by motor start-ups or transformer inrush currents—without interrupting the circuit. This prevents nuisance tripping while still providing robust protection against sustained overloads and short circuits.

The fuse is rated for 250V AC and features a high breaking capacity of 1.5kA, making it suitable for a wide range of domestic and industrial applications. Its compact 5mm x 20mm metric size (equivalent to 0.2” x 0.79”) is a standard dimension, ensuring compatibility with a vast array of fuse holders, panels, and equipment. The ceramic construction offers excellent insulation properties and mechanical strength, contributing to a long service life and dependable operation.

Key Applications & Benefits

• Reliable Overload Protection: Safeguards sensitive electronic devices, power supplies, and control circuits from damage due to excessive current.
• Motor and Transformer Protection: Ideal for protecting equipment with high inrush currents, thanks to its time-delay design.
• Versatile Compatibility: Its standard size makes it a direct replacement fuse in many European and international appliances and electrical installations.
• High Safety Standard: The 1.5kA breaking capacity ensures it can safely interrupt high fault currents, minimising the risk of fire or equipment damage.

A staple component for electricians, technicians, and DIY enthusiasts, the SIBA ceramic fuse is an essential part of any electrical safety,
