GBA-2

GBA-2 is an electrical specialty fuse that is commonly used in circuit boards, power supplies, and transformers. It is designed to protect circuits from over-current and short circuit conditions. It can also provide protection from other electrical faults, such as inductive spikes, reverse polarity, and electromagnetic interference.

GBA-2 has a semiconductor element embedded at the heart of the fuse that acts as the switching element. The active element is a resistor that releases energies causing the fuse to blow in the event of an over-current condition. The resistor is connected to a switch, which triggers the fuse when the current exceeds its rated value.

A GBA-2 fuse typically has a breaking capacity of 200A and a peak current rating of 1500A. The fuse has a cold resistance that is 100 times the rated current. The design of the fuse ensures that only the current exceeding its rated value blows the fuse. It also has low thermal inertia, allowing it to blow in a few milliseconds.

A GBA-2 fuse can be used in a variety of applications, including power supplies, motor controls, and circuit boards. It is often used in high power applications, such as industrial motor controls, electronic ballasts, and HID lighting systems. The surge protection characteristics of the GBA-2 fuse make it ideal for protecting sensitive components and circuits, such as computer processors, memory chips, and DC-DC converters.

When using GBA-2 fuses, it is important to ensure proper circuit protection. To prevent false trips, the fuse must be selected appropriately for the application. Additionally, the size and type of the fuse must be matched to the device that it is protecting. The fuse must also be placed in a suitable location in the system to ensure efficient operation.

GBA-2 fuses provide reliable protection from over-current and short circuit conditions and are widely used in a variety of applications. It is important to select the correct size and type of fuse for the application and to install it in a suitable location to ensure proper protection and reliable operation.
