What is HLT-D Fuseholders?

HLT-D fuseholders are a special type of fuseholder designed for use with high-voltage fuses (in the medium-voltage range). They have been designed to meet the requirements of IEEE C37.113 and UL489 standards for high-voltage AC and DC systems. The HLT-D range of fuseholders are designed to accept a wide range of current fuses and are suitable for use in a variety of industrial and commercial applications.

Applications of HLT-D Fuseholders

HLT-D fuseholders are used in many different types of applications. These include:

• Industrial and commercial power systems
• Computer and server rooms
• Uninterruptible Power Supply (UPS) systems
• Generator systems
• SCADA and process control systems
• Emergency power systems
• Switching systems

The HLT-D range of fuseholders is designed for use with a range of high-voltage fuses from the most common DIN clip type to high-voltage cartridge type fuses. HLT-D fuseholders can be used in a variety of industrial and commercial power system applications. They are also suitable for use in a range of process control, computer and server rooms, generation plants, emergency power systems and power switching systems.

Working Principle of HLT-D Fuseholders

HLT-D fuseholders are designed to provide a robust and reliable means of connecting high-voltage fuses to a circuit. They feature an insulated base which houses the terminals and includes a mechanism for locking the fuse in place. The base also features a series of vent holes which allow the fuse to vent heat generated during normal operation.The fuseholder is connected to the circuit via a wiring system. The wiring system consists of a conductor and conductor terminal, conductor connector and/or block, conductor cover and junction box. The conductor is terminated in a terminal and is connected to the conductor connector which in turn is connected to the fuseholder.The fuseholder includes a mechanism that holds the fuse in position. This mechanism consists of a series of contacts that allow the fuse to move during normal operation whilst also providing secure termination and protection from accidental disconnection. The mechanism also includes a locking feature which helps to ensure that the fuse is securely in place and unlikely to become accidentally disconnected.

Conclusion

HLT-D fuseholders are designed to be used in applications where high-voltage fuses need to be connected to a circuit. They are designed to meet the requirements of IEEE C37.113 and UL489 standards and are suitable for use in a variety of industrial and commercial applications. HLT-D fuseholders feature an insulated base housing the terminals and a locking mechanism for keeping the fuse in place. The fuseholder is then connected to the circuit via a wiring system which helps to ensure reliable termination and protect against accidental disconnection.
