Fuseholders

A fuseholder is a device that provides a safe and convenient way to contain and protect a fuse from damage, as well as any damage caused by the fuse. To effectively protect a circuit from potentially dangerous over-current conditions, a fuse must be properly installed in a high-quality fuseholder that holds it securely and is designed to direct the heat of an over-current situation away from the fuse and down into the body of the holder. This article examines the application field and working principle of H60030-1SR, a type of fuseholder.

Application Field

H60030-1SR is designed for use with most standard, UL-approved power distribution fuse sizes, including American Commercial Standard-type “Mersen” UL listed fuses. This fuseholder offers a three-phase fused safety disconnect system with up to 200A maximum continuous loading. It is suitable for many applications, such as motor protection, lighting circuits, control circuits, and instrumentation. It can also be used as a safety disconnect in commercial and industrial installations.

Working Principle

H60030-1SR is designed to provide superior over-current protection and fuse ejection. It is made with a positive-locking thermoplastic frame, corrosion-resistant internals, and flame-resistant thermoplastic components. When the fuse heats up due to an over-current situation, a positive-locking mechanism acts to separate the fuse from the contact points while venting the fuse body. The device also has a visual indicator which shows if the fuse has been ejected. The device is also designed to be easily accessible and safe to use.

The H60030-1SR also includes an inner interlocking sleeve which prevents accidental insertion of the wrong size fuse. It also ensures that the fuse is properly seated in the holder when it is installed. Additionally, it allows for pre-wiring of the holder prior to installation, which eliminates field wiring and reduces installation time.

The device also includes substantial electrical contacts which provide the connection between the fuse and the device. This ensures that there is a smooth flow of current between the two without any arcing or voltage drops. Additionally, the device provides a reliable connection between the fuse and the device, and it can be easily removed in the event of an emergency. The device is also designed to be both UL and CSA listed, allowing it to meet local safety standards.

Conclusion

H60030-1SR is designed to provide a secure and reliable way to contain and protect a fuse from damage, as well as any damage caused by the fuse. It is suitable for many applications, including motor protection, lighting circuits, control circuits, and instrumentation. It is designed to be easily accessible and safe to use, with positive-locking thermoplastic frames, corrosion-resistant internals, and flame-resistant thermoplastic components. Additionally, it includes substantial electrical contacts which provide a reliable connection between the fuse and the device.
