The 021306.3MXP fuse is a class of equipment integral to industrial and electronic settings, part of a larger class of overcurrent-oriented units referred to as ‘fuses’. As current density is a primary factor in electronic failure, the 021306.3MXP fuse is designed to provide a layer of protection to electronic devices by triggering and shorting the circuit in the event that a potentially damaging current is detected.

The 021306.3MXP fuse is comprised of two main parts, the fuse element and the body. The fuse element, housed in a body, is designed to maintain an electrical connection between two points unless a peak current permeates the circuit. The specific performance parameter of the fuse determines when a fault current triggers the fuse element.

Since the potential for short circuits and other overcurrent scenarios poses inherent threats to the long-term efficiency and health of many electronic components, the 021306.3MXP fuse is purposely designed to detect and short fault currents before downstream components are damaged beyond repair. When the fuse element is struck by the fault current, a thermally-sensitive element will expand and break the electrical connection, forming an open circuit and protecting any downstream components from the harmful current.

In many applications, the 021306.3MXP fuse is designed to safeguard circuits from long-duration overloads as well. In this application, the electrical connection will remain intact until a critical overload span—predetermined by the fuse’s performance data sheet—is reached. When this critical current overload is detected, the thermally-sensitive element will quickly expand, and the electrical connection will transition to an open state, terminating the flow of current to and from the device.

The 021306.3MXP fuse’s applications are vast and varied, being used in all sorts of settings where reliable, safe overcurrent and short circuit functionality is required. Common use cases include industrial control systems, automotive, telecommunications, public utilities grids, and power distribution systems. In many modern settings, the 021306.3MXP fuse has been replaced by thermal magnetic unit breakers, but can be used in most conventional, dated settings where its superior performance is sought.
