    Ceramic tube

    A ceramic tube fuse is a type of electrical safety device designed to protect circuits and equipment from overcurrent conditions. It consists of a cylindrical, hollow ceramic tube that contains a fuse element. Ceramic tube fuses are typically used in applications where electrical protection is necessary, and they offer several advantages:

    • They are available in various current ratings, and when the current exceeds the rated value, the fuse element inside the ceramic tube will melt or break, interrupting the circuit.
    • Some ceramic tube fuses have a time-delay characteristic, also known as "slow-blow" or "time-lag." This means they can tolerate short-term overcurrent’s without blowing, making them suitable for applications where brief power surges are common.
    • High-Temperature Resistance - ceramic material is known for its high-temperature resistance, which allows these fuses to operate in environments with elevated temperatures without deforming or breaking.
    • Ceramics offer good chemical resistance, making them suitable for applications where exposure to corrosive substances may occur.

    Ceramic tube fuses are widely used in various industries, including automotive, industrial, electronic, and residential applications. They protect sensitive electronics, motors, appliances, and electrical circuits from damage due to overcurrent conditions. The choice of a specific ceramic tube fuse depends on the application's current requirements, time-delay characteristics, and environmental conditions.
