The RJS 400-R STD application field and working principle can be classified under Electrical, Specialty Fuses. This classification includes a range of system fuse protection applications from low to high voltage. The RJS 400-R STD range is particularly useful in protecting against external and internal noise and power-line surges multiple times without needing to be reset.

When used in low voltage circuits, the RJS 400-R STD is able to offer reliable protection against multiple short circuits whilst at the same time providing insulation against arc flash incidents. This type of fuse is suitable for use in electronic equipment, appliances, and other high-power interruptions as part of a safety system. Its design ensures that it will not need resetting in the event of an overload.

The construction of the RJS 400-R STD fuse makes it extremely reliable due to its two-part design which consists of a high-voltage and short circuit arc-quenching element which can be easily connected to the supply circuit. It is designed with a low-profile version in order to provide better protection in tight spaces such as switchboards and circuit panels. The fuse is also able to operate over wide temperature and current range in order to support a wide range of applications.

The working of the RJS 400-R STD fuse is based on its two elements, the first of which is an arcing element which is a disc-like structure designed with resistive elements which help to protect the fuse from overcurrents. This element has an extremely fast response time and is essentially a short circuit breaker, designed to break down the circuits when power is cut off. The second element is a quenching element which is made up of metal wire and is designed to control the amount of heat produced when the arcing element is activated.

In addition, the RJS 400-R STD fuse is designed with a unique safety current limiter (SCL) which is designed to limit the amount of current that can flow through the fuse and prevent overvoltage of the system. This SCL is also designed to provide protection against arc flashes and has a built-in alarm system which will alert users to a problem in the system. Lastly, the fuse is also designed with an internal arc fault protection device which is designed to detect and isolate arc faults in the system.

Overall, the RJS 400-R STD range is an ideal choice for low to high voltage system fuse protection applications due to its robust construction and reliable performance. The built-in safety features provide enhanced protection against short-circuits, overloads, and arc flashes as well as providing necessary insulation in sensitive areas. In addition, the unique SCL and internal arc fault protection system provide further protection to the system ensuring the safety of equipment and personnel.
