The FNA-2 fuse is a type of specialty fuse designed for applications with limited space and low voltage (≤ 30 volts ac or dc). It is a two-pole device, meaning it can be used in circuits with up to two negatively charged current paths. This versatility makes it suitable for various control and short-circuit protection applications, such as motor circuits, HVAC systems, commercial and industrial installations.
The FNA-2 fuse is constructed with metal housing, an internal element, and a replaceable end cap. The internal element is made from a fusible alloy, a combination of metal and insulating material that melts when a set current level (amperage) is reached. This proprietary alloy has specific characteristics that enable high interrupting ratings with very short alert-times.
The FNA-2 fuse is rated for low voltages and currents suitable for household circuits and other applications with moderate power requirements. It is UL- and CSA-certified for safety, and CCC-approved for use in China. FNA-2 specialty fuses are also available in a range of sizes, from 6.3mm to 30mm, to fit different applications.
The working principle of the FNA-2 fuse is simple but effective. When a circuit is powered, current flows through the fuse and is constantly monitored. When the current exceeds the fuse\'s amperage rating, the fusible alloy inside the fuse heats up and melts, interrupting the power flow through the circuit. This prevents any further increases to the current, causing the circuit to be protected from unwanted electrical spikes or surges.
The FNA-2 fuse is commonly used in motor circuits, HVAC equipment, and other commercial and industrial installations. It is designed for applications with limited space and low voltage. These specialty fuses have been UL- and CSA-certified for safety and CCC-approved for use in China. The fuse is rated for low voltages and currents and is available in a range of sizes. The FNA-2 fuse operates on the simple yet effective principle of melting the fusible alloy inside the fuse when a set current level is exceeded.
