The Omega 25.1500.24 ST522163 is a 5x20mm cylindrical glass fuse rated 630mA at 250V. The slow-blow (delayed) characteristic tolerates short inrush currents, making it suitable for transformers, power supplies, and household electronics where instantaneous fuses would nuisance-trip on start-up.

The transparent glass body lets you confirm at a glance whether the element has blown, and the nickel-plated brass end caps deliver reliable, corrosion-resistant contact. The pack of 5 covers replacement and spare-kit needs.
