Fuses

Fuses are a type of safety device typically installed in consumer electronics to protect against current or voltage overloads. A fuse is designed to limit current flow in an electrical circuit by creating an open circuit when it senses an electrical overload (often due to an accidental short-circuit or a surge of voltage).

The 0697W2000-01 fuse is a mid-range current limiting fuse that is designed for use in consumer level audio/video equipment. Its rated current is 20A and it has a rated breaking capacity of 115 vac or 230 vac for single phase applications. The 0697W2000-01 is compliant with many UL and CSA standards for electrical safety.

Application

The 0697W2000-01 fuse is designed to provide protection for audio or video equipment from overheating and fire due to electrical accidents. It is compatible with medium current applications where the rating is between 10 A - 90 A and where the voltage rating is lower than 230 Vac. Some examples of applications where the 0697W2000-01 is used include: high-end stereo installations, video gaming systems, televisions, DVD players, Blu-Ray players, and home theater systems.

Working Principle

The 0697W2000-01 operates on the thermal-magnetic principle, where current is limited by both thermal and magnetic effects. The thermal effect is immediate, and the fuse will respond to high levels of current almost instantly by melting and opening the circuit. The magnetic effect causes the fuse to open the circuit at a predetermined level of current and time. The 0697W2000-01 has a time-delay function, meaning that it will open the circuit with a gradual increase in current. This time delay will allow the user to disconnect the power before the fuse opens the circuit, preventing damaging spikes.

Additionally, the 0697W2000-01 features a fail-safe design that will only allow the fuse to reset once the power source has been disconnected. This ensures that the fuse will not inadvertently reset while it is still damaged or overloaded.

Conclusion

The 0697W2000-01 fuse is designed for consumer level audio/video equipment that require mid-range current protection. Its time-delay and fail-safe design make it an ideal choice for those applications. It is compliant with many UL and CSA standards for electrical safety, making it a safe and reliable choice for any medium current application.
