Electrical, Specialty Fuses: 170M6239 Application Field and Working Principle

The 170M6239 is a UL listed dual element fuse with special ratings and approvals and a variety of applications. The fuse is suitable for use as a circuit breaker in aerospace and commercial aircraft panels. It is designed to protect electrical circuits from over current and short circuit faults.

The 170M6239 from Eaton Corporation protects aircraft equipment such as generators and starters from both over-current and over-voltage. It also protects the aircraft’s electrical system from dangerous overloads, lightning strikes, and other abnormal abnormalities that could cause fire or equipment damage. This fuse has a wide variety of applications in aerospace, commercial, and industrial electronics, as well as in automotive and marine applications.

Application Fields

The Eaton 170M6239 is a dual-element fuse suitable for installation in electrical equipment, including components, assemblies, and systems. It is suitable for use in aerospace, commercial, and automotive applications, as well as in industrial and marine applications. The fuse is suitable for use in circuits up to 600 volts AC and 250 volts DC. It has a UL 98 listing for use as a circuit breaker in the aerospace and commercial aircraft panels.

The fuse is approved for use as a circuit breaker on aircraft panels up to 350 volts. It is suitable for use in aircraft where high altitude and vibration levels are present. The fuse is also approved for use in industrial, marine, and general purpose applications. It is also approved for use as a circuit breaker on electrical power tools up to 600 volts.

Working Principles

The Eaton 170M6239 is a dual element fuse designed with a fast-acting element and a current limiting element. The fast-acting element is designed to respond quickly to an over-current condition and open the circuit in a timely manner. The current limiting element is designed to limit the duration of the over-current condition, allowing more time for the fast-acting element to react. The dual element design protects the circuit from both over-current and over-voltage conditions.

When an over-current condition occurs, the fast-acting element heats up and reacts immediately. It then opens the circuit, preventing further injury to components or wiring. The current limiting element is designed to limit the duration of the over-current condition, allowing more time for the fast-acting element to react. This prevents damage to both the device and the components in the circuit.

When the over-current condition subsides, the current limiting element will delay the re-energizing of the circuit. This helps protect the device and the components in the circuit from further damage. The fuse will then return to its original condition and the circuit can be safely re-energized.
