3ABP Fuses

3ABP fuses are types of electrical fuses that are designed to be used in a wide range of applications. These versatile fuses are commonly used in consumer electronics, automotive, household, industrial and telecommunications systems. The main purpose of these fuses is to provide a reliable protection against overload and over current situation.

Application Field

3ABP fuses have various applications in a range of modern electronic systems. It includes the consumer electronics such as TVs, Radio, Cameras, Radios, Home Theatre Systems and Computers. In the automobile industry, the 3ABP fuses are applied in various components such as starter, alternator, cooling fan and fuel pump systems. They also have applications in high voltage circuits and the telecommunication industries. In industrial settings, 3ABP fuses are widely used in providing overload protection to motors, transformers, controller boards, and ethernet switches.

Working Principle

3ABP fuses consist of tiny copper wires which are embedded in a heat-sensitive material and are wound with an insulation coating. The wires form an electrical bridge, connecting the main fuse element with a circuit. The electric current passing through the device passes through the wires. When the current exceeds the rating of the fuse, the wires begin to heat up, causing the protective layer of insulation to melt and the two ends to be disconnected. This eliminates the risk of over current. Once the fuse is opened, it must be replaced in order for the circuit to function again.

In addition to over current protection, 3ABP fuses also provide surge protection by absorbing the voltage spikes created by excessive transient current. This prevents damage to the circuit by preventing the current from reaching its peak.

3ABP fuses are highly reliable and are an important part of any electronic system. They ensure that excessive load and current do not cause any damage to the sensitive electronic components.
