Terminal Fuses
Terminal fuses are protective devices used at electrical connection points to prevent damage from overcurrent. They interrupt the circuit if current exceeds a safe level. Commonly used in control panels, automotive, and power systems, they come in types like cartridge, bolt-on, or blade. Key specs include current/voltage ratings and speed (fast or slow-blow).
