Electrical Specialty Fuses are an important part of the electrical system, providing essential protection for sensitive electronic components from current spikes and other irregularities. The 12OHGMA63 fuse is a high current, mid-range taut wire glass tube fuse that provides reliable protection for electrically exposed areas in mines, chemical process plants, and marine applications.

The 12OHGMA63 fuse is a “slow-blow” fuse, also referred to as a “time-delay” or “delay-action” fuse, meaning that it react slowly to changes in current. This allows it to provide protection to sensitive components from momentary current spikes or irregularities without tripping or blowing the fuse.

The 12OHGMA63 uses a taut wire system, a method of suspension, or suspension wire, for a fuse element. It consists of two helically wound tungsten wires that are connected to the terminals at both ends. The two wires produce an interference pattern when current is running through them, causing them to vibrate and collide with the heat-resistant glass tube, creating a fuse element and allowing it to diffuse the heat. This carefully designed suspension system is able to provide the fuse with stability and sufficient flexibility to react quickly to current fluctuations.

The 12OHGMA63 fuse can generally be used in circuits with line voltages of up to 600VAC or 750VDC, with interrupting ratings up to 100A. It’s capable of handling a steady state current up to 150A with a fast response time-delay action. It’s also in compliance with UL, CSA, and VDE standards.

The 12OHGMA63 is a great choice for applications that require a reliable and fast-acting fuse. It’s typically used to protect heavier circuits, such as motors and pumps, circuits that are in hazardous areas, or in areas with extreme vibration and conditions. It’s also commonly used in the aviation and marine industries due to its robust construction and reliable performance.

In summary, the 12OHGMA63 is an ideal fuse for applications that require both an intermediate current rating and a fast-acting time-delay action. Its taut wire design provides it with stability and flexibility, and it’s capable of handling a wide range of current ratings and interrupting ratings. It’s also in compliance with many safety standards, making it a great choice for applications that require a reliable, safe, and effective protection.
