Which type of fuse is used for circuits rated at 100 amps or more?

• A. Glass fuse
• B. Cartridge fuse
• C. Knifeblade fuse
• D. Blade fuse

Answer: (C)

The knifeblade fuse is designed for high-current applications, typically rated for circuits at 100 amps or more. This type of fuse provides a robust and reliable connection that can handle higher loads without risk of overheating or failure. Its design allows for easy installation and replacement, often seen in industrial settings or critical applications where high current protection is essential. In comparison with the other fuse types, glass fuses are generally used for lower amperage circuits and do not provide the necessary capacity for 100 amps or more. Cartridge fuses can accommodate higher ratings but are typically found in specific applications and may not offer the same ease of access as knifeblade fuses. Blade fuses, while common in automotive applications, are generally not rated for high currents such as 100 amps, making them unsuitable for this context.
