PTC Resettable Fuses refer to electronic devices that protect circuits against current overloads. These fuses can not only prevent damage to circuit components, but can also be automatically reset for the continuity of circuit operations and protection, making them the ideal choice for many applications. The 30R090UU is one such product in the market, designed to provide excellent current protection and reset capability. It is UL (Underwriters Laboratories) Recognized and designed to meet all UL requirements. In this article, we will explore the application field and working principle of 30R090UU.

Application Field: The 30R090UU is a versatile product, capable of providing surge protection and current overload protection in many applications. Some of its common applications include:

  • Air conditioning systems and other HVAC systems
  • Medical equipment
  • Power supplies
  • Data storage and networking devices
  • Automotive circuits such as airbag systems and airbag deployment controllers
  • Other electrical and electronic equipment requiring surge and over-current protection

The 30R090UU can be used in a wide variety of industries, including manufacturing, automotive, aerospace, and medical. It is designed to provide maximum protection for sensitive electronic components, even in extreme conditions.

Working Principle: The 30R090UU is a Polyfuse Resettable Fuse, featuring two elements, a PTC (positive temperature coefficient) element and a bimetallic strip. This fuse is designed such that when overloaded, the heat generated by the PTC element causes the bimetallic strip to open, thus, breaking the circuit. When it cools down and the overload is cleared, the bimetallic strip closes and the fuse is reset. The 30R090UU is designed to provide high current protection up to at least 9A in an AC environment.

In addition to providing short-circuit and overload current protection, the 30R090UU also protects against surges or spikes in current. This is accomplished by the PTC element, which responds quickly to any changes in the flow of current and allows the fuse to break the circuit before the surge can cause any damage. This helps protect the sensitive electronics in a circuit from damage.

The 30R090UU also has a unique feature known as "reverse leakage blocking". This feature is designed to prevent current from flowing in the backward direction when the circuit is broken due to an overload. This helps prevent damage to the delicate components in a circuit and prolongs the life of the system.

The 30R090UU is designed to provide efficient and reliable circuit protection. It can be used in many applications and is UL Recognized for its excellent performance. With its two-element design and reverse leakage blocking feature, the 30R090UU is an ideal choice for a wide range of applications.
