067301.6DRT4P

067301.6DRT4P Application Field and Working Principle

The 067301.6DRT4P series is a fast-acting, high-breaking fuses meeting the requirements of UL 248. They have a wide range of uses in the industry, such as consumer electronics, telecommunications, medical devices, lighting, research and development, vehicle scene, electrical and industrial, and automation control. The product meets the requirements of the following standards, IEC 60269-1, UL 248-13, CSA22.2 No. 248-13, and GB13539-92.

Application Field

The 067301.6DRT4P series fuses are used in the application fields mentioned above, and can be used in any system that requires overcurrent protection. Since fuses of this series are UL and CSA verified, they can provide additional safety approvals when combined with other UL or CSA accredited products for product certification.

Working Principle

The 067301.6DRT4P series fuses are fast-acting fuses, meaning that they will open very quickly when current levels exceed their ampere rating. This is due to the time-delay element embedded within the fuse, which limits its current carrying capability. When the circuit current exceeds the specified ampere rating, the internal element melts and the circuit is disconnected, thus protecting the system by disconnecting it from the power supply.

Unlike other types of fuses, the 067301.6DRT4P series does not require a device to reset the circuit once the overcurrent situation has been removed. Once the melted element is replaced, the system is automatically reconnected to the power supply.

In order to ensure the safety of the system, the 067301.6DRT4P series fuses have a sentry circuit that helps to indicate when the fuse needs to be replaced. When the heat produced by the internal element reaches dangerously high temperatures, it triggers an indicator light to turn on, warning the user to replace the fuse.

Features

The 067301.6DRT4P series has several features that set it apart from other types of fuses. These features make it particularly suited for use in applications where it is important to ensure the safety and reliability of the system.

• Internal time-delay element for rapid and consistent trip times
• UL and CSA verified
• High-breaking capacity
• Sentinel circuit to indicate when the fuse needs to be replaced
• Low power consumption
• Resets automatically once the overcurrent has been removed

The 067301.6DRT4P series is a reliable and cost-effective solution for overcurrent protection in a wide range of applications. With its fast trip time, high-breaking capacity, and other features, this series of fuses is well-equipped to protect any system requiring overcurrent protection from damage due to overcurrent situations.
