BK/S-8201-7 Application Field and Working Principle

The BK/S-8201-7 Fuse Holders is one of the most versatile types of fuse holders on the market today. It offers a wide range of applications in both in house and industrial settings. The BK/S-8201-7 fuseholder is a 3-pole design specifically intended for use in high-current-carrying applications for single-pole overloads.

Design and Structure

This fuseholder is designed with three poles of protection, each with a current rating of up to 100A. This structure ensures reliable and robust protection against current overloads. The BK/S-8201-7 is encased in a durable plastic housing. The output terminals are clearly marked for the user\'s convenience and they are easily accessible and can be accessed without the need to open the casing of the holder. This design ensures reliability, safety, and easy installation.

Application Field and Working Principle

The BK/S-8201-7 can be used for a wide variety of applications in both residential and industrial settings. It is suitable for use in high-current-carrying circuits, including: control equipment, air-conditioning, refrigeration, lighting, heating, and air sensing equipment. It can also be used in high-power applications such as power transformers, electric driven machines, and heating systems. This type of fuse holder is suitable for particular applications like appliance motors and UPS systems.

The working principle of the BK/S-8201-7 is simple. When a current overload occurs, the current in one or more of the three poles of the fuseholder will exceed the rated current. The overcurrent will cause the contact to heat up quickly thereby creating a short circuit and tripping the circuit breaker. This will interrupt or trip the circuit and protect it from further overloads and damage.

Safety Features

The BK/S-8201-7 has several safety features that make it particularly effective at protecting circuits. Firstly, the contact material is designed to provide an insulated, highly conductive, tribrass contact. This ensures a low contact resistance, meaning less heating of the contact which can protect against fire hazards. Additionally, the contact material is designed to provide an arc-resistant insulation, protecting against arc flash.

The fuseholder is also designed with a safety lever, which helps to prevent accidental contact with the contacts. This lever acts as a physical barrier to keep hands away from the contacts and adds an additional layer of safety. Furthermore, the product is tested to European safety standards, providing enhanced peace of mind.

Conclusion

The BK/S-8201-7 Fuseholders is a versatile and dependable device used for protecting circuits from overcurrents. It offers a wide range of applications and is suitable for a variety of applications from high-power applications to domestic settings. The product is well designed with insulated contacts, a safety lever, and tested to European safety standards. This provides reliable operation, safety, and peace of mind.
