Fuses are critical safety components in the field of electrical engineering. They are designed to prevent electrical circuits from experiencing damage due to excessive current or overheating. The ABC-2-R is a type of fuse that is designed to ensure the safety of both personnel and equipment. This article is an overview of the ABC-2-R and its application field and working principle.

The ABC-2-R is a fast-acting, non-resettable fuse that is designed to protect circuits from over-current and thermal overloads. It is a two-piece, hermetically sealed unit, consisting of a resistor and a fuse element. The two components are joined together by a special connection and sealed in an epoxy-encapsulated body. The epoxy is designed to prevent moisture from entering the assembly and to also provide excellent protection against vibration, shock, and mechanical stress.

The ABC-2-R is typically used in applications where high current is needed to start electronic elements or in situations where the reaction time of the fuse needs to be particularly fast. It is often found in portable battery-powered devices where flexibility and size of the circuit are important factors. It is also used to protect electrical systems from short circuits caused by lightning. In addition, the ABC-2-R can be used in high-temperature environments, such as in telecommunications systems and power supplies for industrial controls.

The ABC-2-R operates on the principle of thermal expansion. When a circuit experiences an overload, the fuse element will expand due to the high temperature. This expansion causes the resistor element to increase in resistance, thus reducing the current flowing through the circuit. When the overload has been removed, the assembly cools and the resistor returns to its original resistance. The ABC-2-R is non-resettable and must be replaced after use.

The ABC-2-R is a versatile and reliable fuse that provides reliable protection in a wide variety of applications. It is designed to withstand harsh environments and is perfect for protecting circuits from overload damage and short circuits. With its fast response time and hermetic design, the ABC-2-R is an ideal safety component for many modern applications.
