OATO20.TPGLOA Application Field and Working Principle

OATO20.TPGLOA fuse is an important type of fuse used in many electrical and electronic applications. This type is a Class R low-voltage current-limiting power fuse rated for 250V AC/DC, and is suitable for rapid short-circuit protection in circuits, with interrupting ratings of up to 20 kilo-amps. OATO20.TPGLOA also offers a wide range of features such as built-in LED status indicator, high- and low-temperature performance, and a dual-action circuit protection capability.

Application Field

OATO20.TPGLOA fuse is typically used as an overcurrent protection in industrial applications such as power control, electric motors, robotic systems, automation control systems, and photovoltaic systems. It can also be used in mission-critical circuits, such as vital power systems in the medical, defense, and aerospace industries, due to its reliable performance.

This type is also suitable for protecting wiring systems and electronic devices from overload or short circuit current. It can also provide protection against overvoltage and under-voltage conditions in AC circuits.

Working Principle

The working principle of OATO20.TPGLOA fuse is based on the fact that the current-carrying temperature of its fuse element is greater than that of the surrounding components. When the current flow through the device increases, the temperature increases. When the temperature reaches a certain predetermined level, the fuse triggers and breaks the circuit.

The fuse is made of a copper or tin-plated wire, which is connected to two electrical terminals. When the current flows through the device, the wire changes its resistance in proportion to the amount of current flowing through it. As the current increases, the wire\'s resistance also increases, ultimately leading to a rapid decrease in the current passing through the device.

The temperature generated by the current can cause the wire to reach its melting point, leading to the melting of the fuse element. This action then disconnects the circuit, thus serving its intended purpose.

Conclusion

The OATO20.TPGLOA is an important type of current-limiting power fuse suitable for a broad range of applications. Its safe and reliable working principle makes it ideal for use in vital power systems in industries such as defense, medical, and aerospace. In short, it is one of the most reliable fuse types available in the market.
