Which type of fuse is used for ratings exceeding 30 amperes?

Cartridge type fuses are specifically designed for higher current ratings, making them the appropriate choice for applications exceeding 30 amperes. Unlike other types of fuses, cartridge fuses can handle larger currents and voltages, which is essential for protecting electrical circuits that require a robust solution due to their increased load. These fuses are typically encased in a durable housing, providing additional protection against environmental factors and mechanical damage.

Their design allows for the use of various materials that can handle significant electrical loads, which is crucial in preventing overheating or potential failures in high-demand situations. This makes cartridge type fuses versatile and reliable in industrial and heavy-duty applications where the current exceeds 30 amperes.

Glass fuses, resettable fuses, and plug fuses are generally more suitable for lower amperages. Glass fuses are commonly used for lower voltage and current applications, while resettable fuses (also known as polyfuses) are designed for circuit protection at lower ratings and can be reused after a fault is cleared. Plug fuses are traditionally used in household applications but typically do not cater to the demands of higher amperages like those served by cartridge type fuses. Therefore, based on their design and ratings, cartridge type fuses are the most
