Introduction

The BK/GDC-400MA is designed for high-current applications and is intended to protect circuits from unexpected overcurrents that could cause damages, such as short-circuits, overcurrents, and overloads. This device is commonly used in power distribution systems, industrial machine controls, building automation systems, and other applications that need to control and protect high-current loads. It is also used to protect motors and circuits from damage when large inrush currents are triggered during the start-up process.

Application Field and Working Principle

The BK/GDC-400MA fuse is a type of overcurrent protection device that can be used in a wide range of applications. It is designed to protect circuits from overcurrents, short-circuits, and/or overloads. This device is capable of handling high current levels, up to 400A. It is commonly used in motor applications, industrial machine controls, and power distribution systems. The working principle of this fuse is simple. It is designed with a fusible metal element that acts as the overcurrent protection device. When an overcurrent occurs, the fusible element melts, causing a break in the circuit and thus protecting it from further damage. This action can be very effective in preventing damage to the equipment, circuit components, and people who may come in contact with them.The BK/GDC-400MA fuse is designed for use in both AC and DC applications. It can be used with any current ratings from 20A to 400A. It is also available in permanent and re-settable types. The re-settable type comes with a reset switch that can be triggered to restore the fuse to its normal operating state. The BK/GDC-400MA fuse is UL and CUL certified, making it safe and reliable for use in various applications. It is also RoHS compliant, meaning it has been designed and manufactured in a way that does not harm the environment.

Conclusion

The BK/GDC-400MA is a high-current fuse designed for applications requiring overcurrent protection. It is capable of handling currents up to 400A and is designed with a fusible metal element that melts in the event of an overcurrent to protect the circuit from further damage. It is available in both permanent and re-settable types and is UL and CUL certified. It has also been designed and manufactured in a way that does not harm the environment, making it a reliable and safe choice for various applications.
