RJS 300-R STD

The RJS 300-R STD is an overcurrent protection device that is designed to withstand extended exposure to extreme currents and temperatures. It is designed for demanding industrial, commercial, and residential applications. The RJS 300-R STD is a “standard” fuse, which means that it is designed for general protection against abnormal operating conditions. It is UL-rated and CSA-certified. This fuse is capable of clearing high inrush currents up to 150 kA, and its high short-circuit current rating minimizes downtime due to nuisance trips.

The RJS 300-R STD is a standard type fuse that uses a thermal-magnetic element. The thermal-magnetic element is made up of two parts: a thermal element and a magnetic element. The thermal element is triggered by an increase in temperature, while the magnetic element is triggered by an increase in current. When the specified current is present, the magnetic element will expand, which in turn will cause the thermal element to react.

When the current reaches the specified current level, the thermal element begins to heat up. As it heats up, it causes a strip of metal inside the fuse to expand, which activates a link, which then causes the fuse to open the circuit. This process is referred to as “tripping”. The tripping threshold for the RJS 300-R STD is 150 kA.

The RJS 300-R STD is made up of high-grade thermoplastic and is capable of withstanding temperatures up to 65°C. It is also rated for short-circuit current of up to 200 kA. The RJS 300-R STD has a high resistance to mechanical shock and vibration. It has a dual- element design, meaning that it can handle both inrush currents and steady-state currents with its two elements.

In a typical application where the RJS 300-R STD is used, a group of motors or other high inrush current loads are wired in parallel. If any one motor were to draw too much current, the RJS 300-R STD would trip, opening the circuit and preventing damage to the other motors. This is a very useful feature in industrial environments where high inrush currents are a potential hazard.

The RJS 300-R STD is an ideal protection device for demanding applications such as motors, transformers, and controllers. Its high short-circuit current rating minimizes interruptions and ensures maximum uptime. The high thermal rating and robust construction make it suitable for a variety of environments and applications. In summary, the RJS 300-R STD is an effective overcurrent protection device that is UL- and CSA-certified, making it suitable for a wide range of demanding industrial and residential applications.
