GMF-1/2 application field and working principle are important topics that need to be understood in the field of Electrical Specialty Fuses. The GMF-1/2 is an ideal choice when it comes to selections for high current industrial applications which require high peak and surge capabilities. It is a multi-conductor fuse type with inserts of different sizes that can be used for applications with very high peak to current ratio. The fuse body has four inserts and it can be arranged in multiple ways; either for higher current ratings or higher current spikes or both.The GMF-1/2 fuse is generally used as an entrance fusing system. It is designed such that it can be easily installed in a wide range of applications. It can be used in both AC and DC systems, for currents up to 800 Amps and surge currents up to 35kV. Its strong performance, low break-over and high short-circuit capability makes it suitable for applications such as motor, welding, LED driving, air conditioning, industrial process control, audio amplifier and power factor controllers.The working principle of the GMF-1/2 fuse is quite simple; when the current passing through the fuse becomes more than the rated value, the fuse will open and break the circuit. This will prevent any further flow of current and protect the circuit from over current damage. It has a single break-over design with four separate contacts at each end. Each contact has a current rating of 50kA and is able to sustain many high-current disruptions. The break-over point, also known as the break-line when the fuse is open, is at the midpoint of the fuse.The GMF-1/2 fuse is designed with a three-wire system; one for power, the other for the ground and one for the control. It has two different ranges of current ratings – the primary and the secondary range. The primary range can be set up for between 200 amps and 800 amps, while the secondary range can be set up to provide better current margin. The control wire ensures the fuse will open sooner if extra current is passed. The primary fuse element is surrounded by a secondary core which is designed to provide extra protection for the fuse.The GMF-1/2 fuse can be used in both AC and DC systems, and it has a higher surge current capability than standard fuses. It also features an innovative design which reduces the need for external over-current protection. It is a highly reliable fuse and can easily sustain many power fluctuations and short-circuits.The GMF-1/2 is a reliable and cost-effective solution for mid-high current industrial applications. It is a reliable and versatile solution that can for many application needs. Its strong performance and high surge capabilities make it an ideal solution for applications where current protection is of utmost importance. The GMF-1/2 is an ideal solution for applications where cost, complexity and safety are highly valued.
