Introduction

The 0678H1000-02 fuses are a form of energy control devices used to protect power circuits from adverse current overloads and faults. Fuses provide safety and longevity to electronic and electrical systems, as well as reliability. They act as an emergency safety feature that will prevent unexpected catastrophic failure when a circuit is overloaded.

Application Field

Due to their high current limiting capability, 0678H1000-02 fuses are typically used in circuits that involve high-voltage equipment such as automotive, industrial, and robotic systems. They are also used to replace circuit breakers in the electrical panel of motor and power switching systems. They are suitable for any application where a high current limit is needed to protect the circuit against over-current conditions, and are available in ratings from 1 amp to 100 amps.

Working Principle

The 0678H1000-02 fuses use a concept known as current limitation. This concept states that when current passes through an over-current protected circuit, the fuse element will heat up and open, breaking the circuit and preventing further current from flowing. A thermal cut-off device is mounted on the fuse element that measures the temperature of the element and if it exceeds a pre-determined limit, the device will trip and disconnect the circuit. It is important to note that the current rating of a fuse element must be at least that of the protected load.

Construction

0678H1000-02 fuses consist of a wire element that passes through an insulating medium. The wire element is usually made from a silver-plated copper alloy for maximum current-carrying capacity. The insulating medium usually consists of a polymer-coated glass tube, a ceramic body, or an anthracite material.

Classifications

The 0678H1000-02 fuses are typically classified according to size, voltage rating, and current rating. A class “R” fuse may be used wherever a general purpose fuse is needed. A class “K” fuse is used in power circuits that require higher current ratings, while a class “T” fuse is used in special circuits such as motors or hazardous environments. The type designation may also designate open fuses (O) and circuit-breaking fuses (C).

Conclusion

The 0678H1000-02 fuses are used to protect power circuits from over-current conditions. They are designed to operate with a certain amount of current flowing through the circuit, and when that limit is exceeded, the fuse will heat up and open the circuit. They are available in various ratings from 1 amp to 100 amps, and can be classified according to size, voltage rating, and current rating. Fuses provide safety and longevity to electronic and electrical systems, and are an essential form of energy control device.
