Fuses are electrical devices that interrupt the flow of electricity when it becomes too strong, and the 2JQ 400-R is one kind of fuses. It is designed to be a type of industrial-grade, mid-size circuit breaker that provides high performance with a contact rating of 400A at 250VAC and high interrupting current (Icn) at 8,000A.

Application Field

The 2JQ 400-R is ideal for protecting lighting, motors, heating elements, signal systems, industrial equipment and commercial applications. It has a wide range of applications in Industry, Mining and Power Plants, which can help operators achieve higher safety and performance.

The 2JQ 400-R is perfect for use in areas where there is limited space, as it has a small size and weight. Its compact design allows for easy installation and maintenance in tight spaces. It supports a wide range of current ratings, which helps the device meet the needs of any commercial and industrial application. The 2JQ 400-R also features high temperature resistance that allows it to be used in hot working environments. The 2JQ 400-R is designed to maintain consistent performance with minimal current leakage throughout its operating life.

Working Principle

The 2JQ 400-R is designed to protect circuits from over-current. It contains two pieces of metal that are connected to each other and surrounded by a heat-resistant material. When the current in the circuit exceeds the rated value, the two pieces of metal heat up, melt the heat-resistant material and break the electrical connection. This interrupts the flow of electricity and helps to protect the circuit.

The operation of the 2JQ 400-R is based on the physical and electrical properties of the components used in its construction. The two pieces of metal, when heated up by the excessive current, increase the resistance of the wire and absorb more energy. This increases the temperature of the wire, resulting in the metal melting and breaking the electrical connection.

The heat-resistant material helps to reduce the risk of sparks and other potential hazards that could be caused by the increased current flow. It also prevents the contacts from sticking together in the case of a short circuit, allowing them to easily break the connection in an over-current situation.

The 2JQ 400-R is easy to install and maintain, making it an ideal option for industrial and commercial applications. It is designed to be safe and reliable, and to provide consistent performance throughout its lifetime. The 2JQ 400-R is a dependable way to protect circuits from over-current and ensure the safety of the equipment and personnel involved.
