About this item
New product out of manufacturer's box
Model: 3NA3 140
The Siemens 3NA3 140 time-delay fuse is an overcurrent protection device used in electrical installations. It belongs to the 3NA series of low-voltage fuses, manufactured by Siemens, a leading company in technology and energy solutions.
"3NA3" refers to Siemens' product line for low-voltage fuses, while "140" indicates the fuse's rated current, which is 140 amperes. The fuse is designed to interrupt the flow of electric current in case of overload or short circuit, protecting electrical components and preventing damage to equipment or fire hazards.
The main characteristic of a time-delay fuse is its ability to withstand momentary overcurrents without interrupting the circuit. It has a specially designed fuse element that melts under prolonged overcurrent conditions but delays its action during short periods of overload, such as motor starting or temporary current surges. This prevents unwanted shutdowns of the electrical system during these transient situations.
The Siemens 3NA3 140 fuse is constructed with high-quality materials, such as low-resistance conductive metals and heat-resistant insulators. It is designed to be installed in suitable fuse holders, and its size and characteristics are standardized to facilitate replacement.
It is important to note that while the fuse provides overcurrent protection, it does not protect against electric shock or insulation failures. These additional concerns should be addressed through other safety measures, such as proper grounding, correct insulation, and electric shock protection devices.
In summary, the Siemens 3NA3 140 time-delay fuse is a reliable device for overcurrent protection in low-voltage electrical installations. Its ability to delay action in transient situations makes it a suitable choice for applications requiring protection against short periods of overload.
