3JQ 125-R Datasheet/PDFFuses
Fuses are passive electrical components designed to protect circuits and equipment from excessive current, overload, short circuit, and overload conditions. They are electrical devices with two terminals, typically made of a metal filament, that melt when too much current flows through them.
3JQ 125-R Application
The 3JQ 125-R is a medium-duty fuse designed for use in aircraft, shipboard and stationary power applications. It offers good overload and short circuit protection, and is ideal for use on systems where it is necessary to protect equipment and circuits from too much current flow, preventing circuit damage or failure.
3JQ 125-R Working Principle
The 3JQ 125-R fuse element is connected in series with the system that is to be protected by the fuse. In the case of an overload or short circuit current, the fuse element melts due to the excessive current, breaking the circuit and thereby protecting the equipment and circuits from damage or failure.
3JQ 125-R Limitations
The 3JQ 125-R fuse is not suitable for all applications. It is important to ensure that the fuse is rated to safely handle the size of the current that the system requires it to protect. In the case of extremely high currents, it is necessary to use other components, such as circuit breakers, to protect the system.
