Definition of 004194322

004194322, also known as time-lag fuse, is a specially designed fuse for protecting small motors and their circuits against overcurrent. It has an internal time-delay, with external overload protection as added assurance. It also offers protection against voltage transients caused by momentary voltage drops, line faults, or unstable power supplies. With power ratings ranging from 5 to 250 Amps, the 004194322 is ideal for protecting motors, pumps, and compressors.

Application Field of 004194322

004194322 are most commonly used in the demanding environments of industrial and commercial control systems, where current fluctuations could disrupt operation or even damage motor-driven equipment. They are also a key component in heating, ventilation, and air conditioning (HVAC) applications, and they are frequently used for surge protection in residential and office equipment. In such systems, the 004194322 can assist in preventing permanent damage when large power surges occur.

In the energy industry, 004194322 are ideal for protecting motors used in both upstream and downstream applications, from oil and gas extraction to electric power transmission. The time-delay element of the fuse works in tandem with the motor’s variable load setting to protect it and maintain correct operation.

Working Principle of 004194322

004194322 consists of a ceramic tube and a metal contact on each end. The thermal part is an enclosed coil of wire containing a resistive material that changes state and recommends when it is subjected to current. A small amount of current flows through the coil at all times, allowing the fuse to detect any overloads without tripping. When an overload occurs, the resistive coil heats up, opening the contacts and creating an open circuit.

The time-delay element is designed to open the fuse in large overload and interrupt situation, such as those caused by short circuits and ground faults. This added protection minimises any motor damage and helps to prevent system down time. The time-delay also allows momentary voltage spikes of up to 6,000 volts – which is why the 004194322 can provide surge protection.

Advantages of 004194322

The 004194322 fuse is designed for circuit protection in demanding industrial, commercial, and energy applications. It offers protection from electrical arc and welding arc currents, it can absorb harmonic energy, and it has the added benefit of a time-delay element. It is also a cost-effective solution which can be installed quickly and easily.

The 004194322 is also UL approved, meeting the high safety standards of industrial and commercial environments. It is designed to be small and compact, taking up minimal space in circuit breakers, and it has a long life expectancy of up to 10 years.
