5NLE175E application field and working principle

5NLE175E is a high voltage, general-purpose, low-voltage fuse, which belongs to the Electrical, Specialty Fuses category. It is a low performance, economical fuse ideal for protecting circuits with low current, low voltage conditions. It is a UL98 dual-element fuse which has two elements in a single fuse that provide both protection and resetting ability in the event of an overload or short circuit.

Characteristics and Features

5NLE175E is a type of fuse that provides overcurrent and short circuit protection. The two elements protect up to 175V AC or DC against overcurrent and short circuit conditions. It is UL/CSA approved for 175V AC/DC and is suitable for protecting circuits up to 600A. It has a wide operating temperature range of -40°C to 80°C and a current rating of 600A. Its nominal current rating is 175V AC/DC.

The 5NLE175E has two distinct features that set it apart from other fuses. Firstly, the 5NLE175E is a UL98 dual-element fuse which has two elements in a single fuse that provide both protection and resetting ability in the event of an overload or short circuit. The unique design of this fuse allows it to offer both protection against overload or short circuit conditions and also reset itself to its original state after the fault has been cleared, so it can continue to provide protection.

Secondly, the 5NLE175E\'s robust and reliable construction makes it suitable for a wide range of environmental conditions. The fuse housing is made of a durable non-self-extinguishing thermoplastic material designed to withstand extreme temperatures from -40°C to +80°C. The fuse’s terminals are also insulated to ensure safe and reliable operation.

Application Field

The 5NLE175E is ideal for a wide range of applications including residential and commercial construction, machinery, and electronic equipment for overcurrent protection. It is also suitable for a range of industrial and manufacturing settings, such as for use in motoring systems, air compressors, and in combination motors. It is UL-listed and certified and approved by major international authorities such as CSA.

Specifically, the 5NLE175E is used in environments where a motor is used to drive a load that is likely to cause an overcurrent or short circuit condition. For example, it is suitable for protecting circuits with low current, low voltage conditions in electric motor drives, compressors and pumps. Additionally, it is used in AC and DC power distribution panels, lighting panels, and other general-purpose electrical control systems.

Working Principle

The 5NLE175E fuse operates on the principle of an electric current going through it, melting the fuse element by the heat generated as a result. Once the current rating of the fuse is exceeded, the fuse element melts, breaking the circuit. This stops the flow of current and prevents any further damage to the equipment or wiring.

The 5NLE175E has two elements within a single fuse that act independently of each other in order to provide both protection and resetting ability. The primary element of the fuse offers protection against overload conditions, while the secondary element helps to reset the fuse after the fault has been cleared, allowing it to continue offering protection. In the event of an overcurrent, the primary element of the fuse will break the circuit, while the secondary element will reset the fuse after the fault has been cleared.

In order to reset the fuse, the secondary element must be manually reset via a push-button located on the fuse’s body. Once reset, the fuse will continue to offer protection and the circuit will be re-established. It is very important to reset the secondary element after a fault has occurred in order to ensure that the fuse continues to provide protection and to prevent further damage to the circuit or equipment.

Conclusion

The 5NLE175E fuse is a UL98 dual-element fuse that provides both overcurrent and short circuit protection. It is suitable for a wide range of applications, from residential and commercial construction to industrial and manufacturing settings. It is robust and reliable, and its unique design allows it to offer both protection and resetting ability in the event of an overload or short circuit. The 5NLE175E’s ability to protect and reset make it an ideal fuse for low voltage, low current conditions.
