0JTD350.X is a type of specialty fuse, designed for electrical protection applications. This type of fuse combines multiple fuse elements into one assembly, providing better performance in applications that require higher amperage. It is often used in harsh environments, such as those that exist in mines, industrial sites and hazardous locations.

Application Field

0JTD350.X specialty fuses can be used in a wide variety of applications. Typical uses include: industrial control systems, substation control, and power distribution systems. They are frequently used for medium and high voltage protection applications, such as those with voltages of more than 600 Volts. In addition, 0JTD350.X specialty fuses can be used for protecting against short-circuits, overloads and sustained over-currents. They are also often used for providing a circuit breaker-like operation to protect circuits against high fault current, but with a minimal time delay. This type of fuse can also be used in applications involving transformers, welding machines, gas supplies, power lines, and military installations.

Working Principle

At the heart of the 0JTD350.X is an assembly of multiple fuse elements. Each fuse element is designed with a certain amperage limit and therefore will blow when the amperage reaches the specified limit. The combined operation of all of the fuse elements creates a multi-level protection system that allows for higher amperage protection. When an over-current occurs, the temperature of the fuse element increases. This causes the fuse element to expand, which in turn causes a current-sensing device to open the circuit. Once the current levels drop below the specified limit, the fuse element is reset through a lever or switch, which allows it to cool down and reset itself.The use of multi-level protection allows for a faster response to electrical surges or over-currents. It also ensures that the circuit is not completely shut down in the event of an overload, allowing for a quick recovery. This type of fuse has the added benefit of being able to handle repeated short-term overloads without needing to replace the fuse. In summary, the 0JTD350.X specialty fuse is designed for applications requiring higher amperage protection. It provides a multi-level protection mechanism, allowing for a fast response to surges or overloads and a quick recovery from them.
