Electrical fuses are used in a wide variety of applications, and the specific type of fuse needed will depend on the voltage, current, and other requirements of the job. The 12OHGMA80 fuse is a specialty fuse designed to protect against overloads and short-circuits. The 12OHGMA80 is a non-indicating knife blade type, allowing occupied housing to remain in place while the fuse is serviced.

This compact, economical fuse is designed to provide resistance to high overloads and short-circuits, making it an ideal choice for low-cost, high-reliability protection in power systems and machinery. The 12OHGMA80 fuse also works well in uninterruptible power systems and actuator loads, as well as in electrical motors and tools.

The 12OHGMA80 fuse consists of a bimetal strip made of two dissimilar metals, typically copper and zinc, which is surrounded by a glass tube containing a gas and salt mixture. Under normal operating conditions, the bimetal strip remains cool, whereas when an overloaded or short-circuit condition occurs, the bimetal strip heats up, expanding and breaking the connection. This action triggers an arcing discharge and the release of the gas and salt mixture. This explosion of the gaseous mixture further breaks the connection, resulting in an instantaneous cessation of electric current. A new fuse can then be inserted and the connection reestablished.

Unlike regular fuses, the 12OHGMA80 provides superior protection and a higher degree of safety for personnel and equipment. If the current exceeding the fuse rating is reached, it will de-energize the system before damage occurs. This delay is beneficial in that it allows a motor to be shut down, preventing stress from accidental overloads.

The 12OHGMA80 has a current rating of 80 Amps and a voltage rating of 600 Volts. It is approved by Underwriters Laboratories and meets the requirements of IEC-60947. The 12OHGMA80 has a response time of 0.5 seconds and a maximum temperature rating of 3500C. It is considered a Category E fuse, meaning it is considered suitable in all environments.

The 12OHGMA80 fuse is a safe and efficient way to protect against overloads and short-circuits. It is relatively inexpensive and has a quick response time, making it ideal for many applications. The 12OHGMA80 provides superior protection and a higher degree of safety for personnel and equipment.
