0697H0400-05 Fuses

Fuses are an important safety device that limits the flow of electricity in a circuit and automatically disengages a circuit upon the detection of an unwanted overload or short circuit. The 0697H0400-05 fuse is a common type of fuse used for higher amperage requirements in industrial, residential, and commercial circuits.

Application Field

The 0697H0400-05 fuse is a dual-element time-delay fuse used for medium voltage applications, ranging from 480V to 600V AC. These fuses are designed to be used in systems that are either operated by manual reset or self-resetting thermal protection overload relay systems. Applications include HVAC units, air compressors, motor control centers, pump control panels, transformers, wind turbines, and other equipment requiring a time-delay fuse.

Technical Specifications

The 0697H0400-05 fuse is composed of a two-element time-delay fuse which meets UL Standard 248-1 and UL Standard 4248-1. It is rated as a 500V, 600A, 200 kA. Its body is constructed from a brass alloy and the element is made from a ferritic alloy. It has good tolerance to shocks of mountings and high temperature operating conditions.

Working Principle

The dual-element design of the 0697H0400-05 fuse contains two melts which work differently depending on the fault in the circuit. The first melt element, known as a ‘non-time-delay’ melt, will immediately break an over-current current, whilst the second melt element, known as a ‘time-delay’ melt, will break the over-current current after a certain amount of time. This element helps to protect against sustained overloads or short-circuits. The time-delay element is designed to respond slowly to gradual increases in temperatures. It also allows the fuse to react in order to prevent the equipment from suffering damage. It limits the damage to the equipment by preventing the current overload from exceeding a predetermined value. This also prevents any further damage to any other connected equipment or circuits. The 0697H0400-05 fuse is designed with a maximum time-delay of 10 seconds. This ensures fast and reliable protection against overloads and short-circuits. It also prevents device damage that can occur as a result of quick disconnection of shunts or incidental connections.

Conclusion

The 0697H0400-05 fuse is designed for medium-voltage applications, ranging from 480V to 600V AC. It is a dual-element time-delay fuse, rated as a 500V, 600A, 200kA fuse. It has a good tolerance to shocks of mountings and high temperature operating conditions. It also has a time-delay element which protects against sustained overloads or short-circuits. It provides fast and reliable protection against overloads and short-circuits by limiting the damage to equipment. This helps to maintain the safety of electrical circuits and equipment.
