JCU-400E

The JCU-400E is an essential part of any industrial instrument system, which is a type of specialty fuses.

This fuse is typically constructed from copper, which has a high melting point so that it can withstand higher temperature and power ranges. It also offers a very precise electrical arc-suppression mechanism that will shut down the circuit in case of a short circuit or a power outage. Its ability to protect any device against over-currents is another great feature of this fuse.

The JCU-400E typically features a Non-Current-Limiting fuse rating, which is why it is often used in applications where current-limiting fuses may not be suitable. With its high surge capability, this fuse is ideal for protecting circuits with high-power switching that is in constant operation. The large diameter disk construction allows for an excellent arc-quenching performance under all conditions, reducing the chance of a short circuit, and thereby reducing the risk of electrical damage. This fuse also has an outstanding ability to withstand repeated on/off cycles, and is well-suited for use in extreme temperature applications.

The JCU-400E is also designed to provide excellent protection for medium voltage circuits. Its low-power disc construction allows for maximum current to pass through during normal operating conditions. The fuse body is designed to minimize magnetic flux, helping to ensure that no voltage drops are created during operation. In addition, its design helps reduce the risk of flashover, thus providing a reliable protection.

The working principle of the JCU-400E utilizes a number of techniques to monitor and regulate the current. A temperature sensitive wire is wound around its base, allowing it to monitor the temperature of the fusible element. When the socket temperature exceeds the melting point of the fuse element, a bi-metal heat switch causes the circuit to open, breaking the connection and thus cutting off the power supply to the appliance.

In addition, the JCU-400E also features an arc suppression coil, which helps to reduce the risk of any sort of electrical arc or fire caused by the release of stored energy. The arc suppression coil will stop the flow of current by dampening the current when the temperature within the fuse rises to a certain level. The coil is designed to absorb the energy of the arc and prevent it from spreading further down the system.

The JCU-400E application field includes applications like industrial instrument systems, automobiles, power supplies, motors, machine tools, and lighting fixtures. In addition, this type of specialty fuse is also used in the communication systems, military equipment, medical equipment, and any other applications where current protection is necessary.
