An application field and working principle of 3JS 1.5-R fuses can be derived from the data sheet that is usually provided with the fuse. In general, a 3JS 1.5-R fuse can be used in enclosed control cabinets, industrial machinery and equipment and other electrically sensitive areas where there is a need for reliable, continuous performance.

The 3JS 1.5-R fuse consists of an UL Class H insulating base with a hollow cylindrical shape that has an inner cavity for the fuse body. The fuse body is typically shaped like a donut and is constructed of silver-plated copper with insulation that is designed to withstand temperatures of up to 1000°F. The inner contact points of the 3JS 1.5-R fuse are tin-plated brass. The fuse is UL rated for up to 150 VAC and has an operating temperature range of between -40 to -75 degrees Celsius.

The working principle of the 3JS 1.5-R fuse is to protect electrical equipment from damage caused by over-currents and high-current spikes. It does this by breaking the circuit when the current reaches the fuses trip level. The 3JS 1.5-R fuse typically has a tripping level that is between 5 and 10 amperes, depending upon the exact application. This allows the fuse to be used in a variety of applications as it can trip regardless of the voltage of the circuit.

The 3JS 1.5-R fuse is typically used in low-voltage circuits to provide overload protection for equipment that may suffer from excess current surges, such as motors, electronic components, and other electrical equipment. As such, they are the perfect solution for protecting your electrical equipment in potentially hazardous environments.

The 3JS 1.5-R fuse is also commonly used in higher voltage applications such as those where the current spikes may be higher than 10 amperes. This is accomplished by the use of a special fuse link. The fuse link can be adjusted to meet higher current requirements and can be used to provide protection in a variety of applications. For example, they can be used to protect electrical equipment in an industrial setting or any environment where current surges are a frequent occurrence.

In summary, the 3JS 1.5-R fuse is an ideal solution for protecting electrical equipment from damage caused by over-currents and high-current spikes. It is capable of protecting equipment in a wide range of applications and is UL rated for up to 150 VAC. It consists of an UL Class H insulating base with a constructed tin-plated brass contact points and a special fuse link adjustment that allows it to be used in higher voltage applications.
