cartridge fuse

A cartridge fuse is a compact, cylindrical safety device designed to protect electrical circuits and equipment from overcurrent or short-circuit conditions. It contains a metallic wire or strip that melts when the current exceeds a rated value, thereby interrupting the circuit and preventing damage to connected components.

Cartridge fuses are widely used in industrial control systems, consumer electronics, automotive circuits, and power distribution panels due to their reliability, ease of replacement, and standardized sizes. Available in both glass and ceramic bodies, they provide clear visual indication of fuse operation and offer high breaking capacity for demanding environments.

Key Features:

• Fast-acting or time-delay (slow-blow) variants

• Voltage ratings typically from 32V to 600V AC/DC

• Current ratings from 50mA to 100A

• Glass or ceramic tube body with metal end caps

• Compact cylindrical design for panel or PCB mounting

• High interrupting capacity for circuit protection

• Available in standard sizes (e.g., 5×20mm, 6×30mm)
