BK/GLR-4 Application Field and Working PrincipleThe BK/GLR-4, also known as an Electrical Specialty Fuse, is a reliable overcurrent protection device designed for industrial and commercial power distribution systems. It is used to protect electrical systems from overcurrents and short circuits caused by electrical faults such as a blown fuse, an overloaded circuit, or lightning.The BK/GLR-4 has a fuse body made of a UL-rated insulating material and a metal casing to protect it from damage due to mechanical forces. Inside the fuse body is a current-limiting element designed to respond quickly to overcurrents, limiting the amount of energy that can pass through it. The fuse is also designed to open quickly to interrupt power to the affected circuit and prevent further damage from occurring.In general, the BK/GLR-4 is designed to be used in applications where there is limited access to the circuit, such as underground and industrial environments. The fuse can work in circuits with a nominal voltage of up to 600V, a continuous current of up to 1000A, and a normal operating temperature of up to 110°C. It also has a wide operating range and is UL-certified, and may be used in any manner in the US.The BK/GLR-4 is designed to work on the principal of inverse-time overcurrent protection. When the incoming current exceeds the maximum current rating of the fuse, the element inside the fuse will heat up due to the current passing through it. As the element heats up, it expands and causes the contacts inside the fuse to open, interrupting the flow of power and thus preventing any further damage to the circuit.The BK/GLR-4 has a number of distinct advantages that make it a preferred choice for many applications. It is fast-acting, reliable, and safe, and is designed to provide the highest level of protection from overcurrent dangers. Moreover, it is cost-effective and easy to install and maintain.Overall, the BK/GLR-4 is an effective and reliable specialty fuse designed to provide protection from overcurrents and short circuits. It is UL-certified, ensuring it has gone through rigorous testing to ensure safety and reliability. Moreover, it is cost-effective and easy to install and maintain. Therefore, it is a preferred choice for many applications in the industrial and commercial power distribution industry.
