SIBA 500mA Ceramic Time Delay Fuse, 5mm x 20mm

The SIBA 500mA Ceramic Time Delay Fuse is a 5mm x 20mm cartridge fuse designed to provide reliable circuit protection for a wide range of electrical and electronic equipment. Its time-delay (slow-blow) characteristic makes it ideal for circuits with inrush currents, such as those found in transformers, motors, and power supplies, allowing it to withstand temporary surges without nuisance tripping while still providing safe protection against sustained overloads and short circuits.

Constructed with a robust ceramic body, this fuse offers excellent thermal and mechanical stability. It is rated for 250V AC and features a high breaking capacity of 1.5kA, ensuring it can safely interrupt substantial fault currents. The compact, industry-standard 5mm x 20mm size ensures compatibility with a vast array of fuse holders, panels, and devices commonly found in consumer electronics, industrial controls, and domestic appliances.

Key Features & Applications

• Time-Delay Protection: The 'slow blow' design tolerates initial current spikes, preventing unnecessary fuse blows during equipment start-up.
• Ceramic Construction: Provides superior durability and heat resistance compared to glass-bodied fuses, making it suitable for more demanding environments.
• High Breaking Capacity: With a 1.5kA interrupting rating, it can safely clear high-level short-circuit faults, protecting downstream components from damage.
• Standard Size: The 5mm x 20mm (0.2” x 0.79”) metric/imperial dimensions ensure it is a direct replacement for countless applications.

This fuse is an essential component for maintenance, repair, and original equipment manufacturing, offering dependable performance to keep your electrical systems safe and operational.
