4NHC00M is a type of specialty fuse manufactured by Eaton. It is a high current circuit protection solution for industrial motor control applications. The fuse is designed to protect high current circuits with varying amounts of load as well as unpredictable events such as lightning strikes.

The 4NHC00M fuse contains a metal alloy thermal element which supports current up to 600V. The thermal element also contains a bimetallic strip which acts as a safety switch that trips at a predetermined temperature when a circuit fault occurs. This ensures the connected circuits are protected from excess heat, overcurrents, and short circuits. The fuse can also be filled with non-conductive gas eliminating any arcing and sparks from the metal alloy thermal element.

The 4NHC00M fuse can be used in a variety of industrial applications such as heavy duty motor controllers, HVAC systems, and electrical panels. The fuse provides a high level of protection for these applications as it can withstand up to 600V and is designed to handle up to 140A uninterrupted current. It is also designed to reduce arc flash hazards as the windowless design prevents any arcing or sparking.

The fuse also has a unique feature that allows it to be tested without having to dismantle it from the panel. The fuse has an internal sensor that detects any current draw on the line and automatically shuts off the power if it becomes excessive. This ensures the circuit will be disconnected before any excess current can damage the components or cause a fire.

Overall, the 4NHC00M fuse is an ideal solution for high current industrial applications. The metal alloy thermal element provides a high level of protection, while the bimetallic strip acts as an additional safety measure. The internal sensor allows for convenient testing and the windowless design provides protection from arc flash hazards. The fuse is also designed to withstand up to 600V and handle up to 140A uninterrupted current, making it perfect for heavy duty motor controllers, HVAC systems, and electrical panels.
