Fuses are used in many electrical applications to protect devices, circuits, and components by interrupting power supply in case of abnormally high currents. The 500NHG2B is a type of specialty fuse that offers reliable and effective protection, and features a variety of features and specifications.

The 500NHG2B is a time-delay Class CC fuse with a dual-element design. It features a current-limiting upper element, which can interrupt small overloads or short-circuit currents, and a temperature-sensitive lower element which can initiate an interruption of higher overload currents. This combination of elements allows the 500NHG2B to offer efficient circuit protection, even when the over-load current exceeds the upper element\'s rating.

The 500NHG2B is designed for use in branch circuits, motor control circuits, and other AC applications. It has a nominal voltage of 600 volts and an interrupting rating of 10 kilo amps. It is also UL Recognized and CSA Certified, making it safe for use in commercial and industrial applications.

In order to ensure that the 500NHG2B is working properly, it is important to understand its operating principles. The fuse operates based on two principle elements, the current-limiting element, and the temperature-sensitive element. When the current in a circuit exceeds the fuse\'s rating, the thermal element begins to heat and eventually melts, which causes the current-limiting element to open a gap in the circuit and interrupt the power supply.

In situations where the overload current is less than the fuse rating, the thermal element will stay cool and the current-limiting element won\'t allow excess current to flow through. In these cases, the 500NHG2B operates as a fast-acting fuse and takes only a few milliseconds to open the gap and interrupt the power.

The 500NHG2B is an ideal choice for many AC applications where protection from short-circuit and overload currents is desired. It offers reliable and effective protection against these types of faults, while also being able to handle non-inductive overloads with a fast operating time. Furthermore, the 500NHG2B is UL Recognized and CSA Certified, making it safe for installation in residential, commercial, and industrial applications.
