TR1/6125TD3-R Circuit Protection

TR1/6125TD3-R Fuses

The TR1/6125TD3-R fuse range has a wide range of applications in the market and is used for circuit protection. It is suitable for general purpose automotive, commercial, and industrial applications providing both time delay and fast acting protection. This fuse is commonly used in power supplies, air conditioning, small motor control applications, and telecommunications.

Basic Characteristics and Standards

The TR1/6125TD3-R fuse has an Amp rating ranging from 1A to 30A. It is also temperature-rated with a melting R current of 068A and an operating temperature range of -40 degrees Celsius to +90 degrees Celsius. This fuse conforms to the UL-2579, CSA 22.2, and EN61913 standards. It has a 440V Interrupting Capacity and a typical Voltage Drop of 0.25V at its rated current.

Construction

The construction of the TR1/6125TD3-R fuse range consists of four main components. These components include a cylindrical metal strip, an insulating material, a lead wire, and a ferrule. The cylindrical metal strip is made from copper or a copper alloy, while the insulating material may be ceramic, glass, or epoxy resin. The lead wire is typically made from tin-plated copper. The ferrule is made of tin-plated brass and serves as the connection point between the fuse and the circuit.

Working Principle

The working principle of the TR1/6125TD3-R fuse range is based on a current overload protection. This fuse has two separate interrupter elements which act independently when the current exceeds a certain threshold. Upon an over-current detection, the first element will respond quickly and open the circuit, while the second element will activate after some time and create a time delayed protection.

Applications

The TR1/6125TD3-R has many varied applications. It can be used as an over-current protection device in power distribution systems, AC/DC drives, motor control applications, and air conditioners. It is also a suitable response protection device in inverters, UPS, and lighting systems. Additionally, it is ideal for commercial and industrial use, providing both fast-acting and time-delay protection.

Advantages

The TR1/6125TD3-R provides a number of advantages over traditional fuse solutions. Firstly, its time-delay protection ensures that there is a greater protection against short circuit. Secondly, the fuse is designed for long-term stability, providing greater protection against future equipment failure. Finally, the fuse is UL-approved and CSA-certified, providing peace of mind for safety and reliability.
