A fuseholder is a device that holds a fuse in place. It is typically used to protect electrical circuits from excessive current and to provide easy access to replace a blown fuse. One type of fuseholder is a HEB-AB series, which is designed for use in a variety of applications. This article will discuss the application field and working principle of the HEB-AB fuseholder.

The HEB-AB fuseholder is designed for use in power supply systems up to 690 VAC. It is most commonly used in equipment such as medical devices, mobiles, computers, and appliances. The HEB-AB works effectively at a wide range of frequencies, from 47 Hz to 63 Hz, and an ambient temperature range of -40℃ to + 125℃. The series is certified to meet international safety standards including UL, CSA, VDE, and RoHS.

The working principle of the HEB-AB is predicated on a single-pole design. This design is comprised of a housing, insert, fuse, and contact. The housing is made from PBT (polybutylene terephthalate) and has two base openings for an M4 screw. The insert is made from PBT and acts as the central hub within the holder for the fuse. The contact is a copper alloy with a nickel-plated surface finish for optimal electrical conductivity and heat dissipation.

When the HEB-AB fuseholder is in use, the insert is inserted into the base of the housing and the fuse is fitted into the insert. The contact is then installed into the base of the housing. This process creates an internal electrical connection between the fuse and contact, allowing current to flow from the contact, through the fuse, and to the circuit being protected.

In the event of an overload, the fuse will blow, disrupting the current flow. This process protects the circuit from any further damage by preventing the flow of current. The blown fuse can then be replaced with a new one to restore the current flow and continue to protect the circuit.

The HEB-AB fuseholder is a versatile product that is suitable for use in a number of applications. It is designed with a single-pole construction which is reliable and ensures the safety of the circuit with which it is connected. With its certification to meet international safety standards, the HEB-AB is a reliable and quality choice for a number of different uses.
