PTC resettable fuses are passive, one-time thermal devices, which have been designed to protect systems, components, and wires from overloads and short-circuits. The PTR030V0900-BK is a 3A fuse, with a voltage rating of 900V DC. It has a low profile design and a wide range of applications in automotive, consumer, and industrial markets.

Application Fields

PTR030V0900-BK can be used in a variety of applications. In automotive, it can be used to protect lights, air conditioning, power steering, and other high-voltage systems. In consumer applications, it can be used to protect TV sets, computers, and other appliances. In industrial applications, it can be used to protect voltage sensitive and critical components. This versatile fuse can also be used in data, communication, and medical markets for protecting equipment and wiring.

Working Principle

PTR030V0900-BK works on the principle of thermal protection. It is designed to react to the heat generated by overloaded current by increasing its resistance and breaking the circuit. The fuse is then reset to its initial low resistance state when the current or temperature drops, allowing the circuit to continue to work. The PTR030V0900-BK is designed with a highly sensitive temperature sensor, allowing it to react quickly and accurately to changes in temperature and current to protect the circuit.

The PTR030V0900-BK has a wide operating temperature range, from -40°C to 125°C, which makes it suitable for a variety of high voltage and high temperature applications. It also has a low power dissipation and an excellent voltage endurance, making it an ideal choice for use in various applications.

Conclusion

The PTR030V0900-BK is a 3A resettable fuse. It has a wide range of applications in automotive, consumer, and industrial markets due to its low profile design, high voltage rating, wide operating temperature range, low power dissipation, and excellent voltage endurance. It works on the principle of thermal protection and can quickly and accurately react to changes in temperature and current to protect the circuit.
