Eaton Cartridge Fuse, 7A Current Rating, 600V AC Voltage Rating - KTK-7 Improve the safety of your electrical circuits with this cartridge fuse from Eaton. The fast-acting device interrupts power supplies to protect equipment against overcurrent. A high rupture capacity of 100,000A clears spikes and low current faults to prevent unnecessary disconnection. The end caps are made from nickel-plated bronze, which supports smooth signal transfer for a quick and reliable response. You'll find this general-purpose fuse in small appliances and cable installations. Features & Benefits • Compact size of 38.1 (L) x 10.3mm (W) for convenient installation in limited spaces
• 600V voltage rating for easy compatibility with high-efficiency applications
• Convenient black colour coding helps with identification in busy setups How does a cartridge fuse work? All cartridge fuses have a wire core that melts when too much current flows through a circuit, breaking the flow to downstream equipment. What's the breaking capacity of a fuse? Breaking capacity is the level of current a fuse can handle without being destroyed. For safety, it must always be higher than the fault current of an electronic circuit.
