Fuses

Fuses are an integral part of the electrical power system and are used to protect the circuit against overloading and short circuit. The 0312.187H is a popular type of fuse used in industrial, commercial and residential applications. Knowing its field of application and working principle is important in ensuring proper use of this device.

Applications

The 0312.187H is a bolt-type fuse and it is designed for use in circuits with a voltage of 600V and current of up to 400A. Typically, the fuse is used for secondary power distribution lines which can include motor control, lighting, air conditioning, power system loads and generator service. This fuse is also used to protect power feeders, motor starters, primary power lines, switchboard, capacitor banks, transformers, rectifier supplies and other valuable power components.

Working Principle

The 0312.187H is designed to contain and limit the amount of current that flows through the device. The operating principle of the device is based on a conductive element with a predetermined melting point that is placed in a sheath or housing. This element is connected to the current carrying conductors of the circuit, with a terminal attached to one end. When the current exceeds the pre-determined value, the conductive element is heated and it melts. This severs the connection between the two conductors stopping all current flow through the device.

Advantages

One of the main advantages of the 0312.187H is its compact size and lightweight construction. This makes the fuse easy to install and requires minimal maintenance. The fuse is also known for its thermal performance and reliability. Due to its design, the fuse is capable of handling high levels of fault current and its protective element responds quickly and accurately. The device provides high Moisture and vibration resistance and is UL listed and CSA Certified.

Conclusion

The 0312.187H is a popular and reliable bolt-type fuse capable of handling high levels of current. The device has a wide range of applications from residential to industrial settings. Understanding the field of application and working principle of the 0312.187H is essential in ensuring proper and safe use of the device.
