Fuses are devices used in electrical and electronic circuits to protect against fault conditions ranging from overloads to short circuits. The 3JQ 125-R TR fuse is a Class R (Fast Acting) fuse specialized for motor circuits. This fuse is featured with AC current ratings of up to 60A per pole, 200kA interrupting rating, and time-delay characteristics. It is designed for motor circuits and is commonly used with MCCBs (Motor Circuit Controllers).

3JQ 125-R TR Application Field

The 3JQ 125-R TR fuse is used for various motor circuit applications, such as pumps, fans, mixers, variable frequency drives, conveyors, and pumps. This fuse offers high performance, fast response, and a wide range of current ratings. It is designed to provide protection for equipment from motor overloads and short circuits. The fuse is also UL and CSA-recognized.

3JQ 125-R TR Working Principle

The 3JQ 125-R TR fuse is a fast-acting device designed to protect motor circuits from overloads and short circuits. It works by limiting the flow of current to the motor circuit, and once the current exceeds the fuse\'s rating, the fuse will heat up and open the circuit, thus preventing damage to the motor or other components connected to the circuit. The heat generated by the fuse will cause it to melt, thus interrupting the current and allowing the motor circuit to cool down before being reconnected. The 3JQ 125-R TR fuse can also provide protection against overvoltage, surges, and high ambient temperature.

Conclusion

The 3JQ 125-R TR fuse is a reliable and versatile device designed for motor circuits. It offers high performance, fast response, and a wide range of current ratings. The fuse is UL and CSA-recognized, and it works by limiting the flow of current to motor circuits, protecting against overloads and short circuits.
