Fuses

3JQ 250-R is a type of fuse, which is widely used in the electrical industry. It is designed to provide protection for electrical circuits and equipment from overcurrents and short-circuits. Fuses are used to protect equipment from overloading and excessive currents, and to ensure the safe operation of electrical systems in a variety of applications.

The 3JQ 250-R fuse is a fast-acting fuse with a high breaking capacity. It is a single-pole fuse-link with an external protection tube and comes in either a 2A or 4A version. It is the perfect choice for high-capacity electrical circuits, such as heavy-duty industrial operations, spot welding circuitry, or large motors and transformers. The 3JQ 250-R fuse has a nominal voltage of 250 VAC, a maximum continuous operating current of 2A or 4A and a maximum operating voltage of approximately 500 VAC.

The working principle of the 3JQ 250-R fuses is based on the concept of ohmic heating. When current flows through the fuse, it generates heat, causing the fuse wire to melt and break the circuit. The fuse wire is designed to heat up and melt quickly when the current exceeds the rated value of the fuse. This limit is usually expressed in terms of amperes.

The 3JQ 250-R fuse is designed to provide an efficient overload protection, as well as a degree of short-circuit protection for the electrical system. The fuse contains a fuse-link, an outer tube, and a notch which indicate the rated current of the fuse. Once the current exceeds the rated value, the fuse-link melts and breaks the circuit, which disconnects the power supply and protects the circuit and equipment from over current.

The 3JQ 250-R fuse is designed for a wide range of applications, from industrial equipment to small home electrical applications. It is ideal for use in light-duty industrial applications, such as spot welding circuits, cranes, hoists and medical equipment, as well as for residential and commercial applications, such as air conditioners, refrigerator motors, pumps and small motors.

The 3JQ 250-R fuse is a reliable and cost-effective solution for protecting circuits and equipment from overcurrents and short-circuits. It is easy to install and replace, making it an excellent choice for a wide range of applications. The 3JQ 250-R fuse ensures safe operation and reliable protection of your electrical system.
