Fuses have been used since the late 19th century to protect electrical circuits from overloads. The 2JQ 750-R is a type of fuse designed for specific applications that require reliable power protection. This article will discuss the application field and working principle of the 2JQ 750-R.

Applications

The 2JQ 750-R is designed for use with high voltage circuits. It is best suited for applications where the rated voltage is between 690V and 1000V AC or between 690V and 1500V DC. The operating current should not exceed 750A in these conditions. The 2JQ 750-R is typically used in commercial and industrial applications, such as substations, power plants, elevators, air conditioners, lighting systems, and industrial control systems.

Working Principle

The 2JQ 750-R is a fast-acting fuse that is designed to protect electrical circuits against overloads. It contains a metal strip that melts when the current passing through the fuse exceeds its capacity. This causes an interruption in the electrical circuit, preventing it from being damaged by the overload. The fuse will often need to be replaced after an overload occurs, as the metal strip will typically need to be replaced in order for the fuse to work properly again.

The 2JQ 750-R fuse is constructed from materials that are able to withstand high temperatures. This ensures that the metal strip will not melt due to the high current flowing through the circuit. It also helps to ensure that the fuse will not be damaged when exposed to extreme temperatures. The metal strip of the 2JQ 750-R is also encased in a specialized resin material that is designed to disperse heat, preventing the metal strip from being damaged.

The 2JQ 750-R is a reliable and durable fuse. It is designed to operate even after multiple overloads, ensuring that the circuit it is protecting is not exposed to any further damage. This fuse can operate for up to ten years with proper usage and maintenance.

The 2JQ 750-R is a useful tool for protecting electrical circuits from overloads. It can be used in commercial and industrial applications, and is a reliable and durable device. The fuse is designed to protect circuits from damage and its metal strip is encased in a special material that dissipates heat, allowing it to operate safely even in extreme conditions.
