044103.5WRA Datasheet/PDFFuses are primarily used for circuit protection, which aims to protect the circuit from fire or hazardous conditions during an overload or short circuit.
0 4 4 1 0 3.5WRA is a quick-acting fuse, one of the most important types of fuses. This fuse is very suitable for the protection of motor, transformer, low voltage circuit and communication line.
Application field
0 4 4 1 0 3.5WRA is used in motor control centers, main switchboards, industrial control circuits and other AC power supplies. They are designed with a high breaking capacity and a short response time to protect high-current circuits against overloads and short circuits.
Working Principle
The 0 4 4 1 0 3.5WRA fuse is a fast-acting fuse with a flat head, a temperature-dependent thermal element, and a silver alloy disc. When the current (I) is greater than the rated current (In) of the fuse, the thermal element will be broken down by the temperature rise. Then the silver alloy disc will disconnect the circuit, causing the fuse to trip and break the circuit. As the time it takes for the fuse to trip depends on the magnitude of the overloaded current, it is called a fast-acting fuse.
The fuse also has other advantages, such as compact size, high breaking capacity, low energy consumption, and high current tolerance. It is also resistant to atmospheric interference, making it a reliable protection device.
In short, the 0 4 4 1 0 3.5WRA fuse is the ideal choice for motor and transformer protection, low voltage circuits and communication lines. With its high breaking capacity and short response time, it can provide effective circuit protection from overloads and short circuits.
