The Omega 25.1500.20 is a standard 5x20mm cartridge fuse with a delayed (slow-blow) characteristic, rated 400mA at 250V. The slow-blow profile tolerates brief inrush currents without nuisance tripping, while still protecting the circuit from sustained overcurrent.

Each fuse uses a glass body with nickel-plated brass end caps for stable contact and resistance to corrosion. The pack contains 3 fuses, ready for use in audio equipment, power supplies, and household electronics.
