Electrical, Specialty Fuses are used in a wide variety of applications because of their versatility. The 315NHG2BI-400 fuse is no exception and is used to safely protect electronic circuits and equipment from surges and overloads. This guide will explain the application fields and working principles of the 315NHG2BI-400 fuse.

The 315NHG2BI-400 is an UL Class H, Supplementary Fuse, designed for use in low voltage AC and DC applications up to 600 volts. It is often used to provide additional protection to equipment already using a main fuse or circuit breaker. The 315NHG2BI-400 is a blade-style fuse with a current rating of 400 amps and a voltage rating of 600 volts. This fuse also is also available in other current ratings and is UL recognized.

Due to its compatibility with a range of applications, the 315NHG2BI-400 is often found in industrial, commercial and residential settings. These settings include air conditioners, HVAC systems, motor control centers and commercial refrigeration. It is also commonly seen in industrial worksites, telecommunications and medium voltage utility applications. The 315NHG2BI-400 can also be found applied to motor starters, power supplies, generator sets, and other motor-driven equipment.

The 315NHG2BI-400 fuse operates on a thermal-magnetic principle. This means that it has two different elements that work together to provide overload and short-circuit protection. The thermal element acts to protect against overloads, and the magnetic element responds much faster to short-circuit conditions. As the current passing through the fuse increases, heat is generated which expands the thermal element. Once the thermal element has expanded to the point that it can no longer dissipate the heat generated, the magnetic element is activated, and the fuse opens. This thermal-magnetic protection provides a faster response to short-circuit conditions while also providing overload protection.

The 315NHG2BI-400 fuse is a versatile and dependable fuse offering reliable protection against surges and overloads. With its range of application fields and its thermal-magnetic protection, it is an excellent choice for protecting critical electronic circuits and equipment in a variety of settings. Be sure to research and understand the requirements of your application before selecting the right fuse.
