Similarities Between Isolator And Circuit Breaker Source: PinterestĪlthough, isolators and circuit breakers are different from each other there are certain similarities between them as well. Therefore they are most commonly found in heavy load devices, for instance, transformers. The built-in arc quenching system enables its usage in case of any circuit faults.įurthermore, the built-in extinguishing system within the circuit breaker enables its high withstanding capacity and helps in creating interruptions during heavy loads and faults. The increase in the intensity of the fault increases the power interruption. These devices instantly identify the fault and prevent or break the electricity flow to the circuit. Considered a protecting device, it protects the electrical equipment against circuit overload or any kind of faults in the circuit. What Is A Circuit Breaker? Source: BenyĪ circuit breaker is the most essential security device of the electrical system. It is the most preferred device for technicians, especially for safety purposes. Furthermore, the isolator prevents any kind of short circuits or faults and safeguards the circuit hardware from any damage. This device disconnects a part of the electrical device from the main current. Furthermore, the isolator has a lesser breaking capacity, and they also lack the built-in arc suppressing system. The presence of an isolator ensures maximum safety during maintenance. Being an offload isolation device it only functions while the current passing through the system is zero. Isolators can be considered as the mechanical device utilized for the disconnection of any electrical equipment or the circuit from the main supply. Many might get confused between them as they are protecting devices, but their purpose is quite different. While the isolators are meant to disconnect in case of an offload situation, the circuit breaker is meant for disconnection during the on-load situation. In this article, we would consider the difference between isolator and circuit breaker. It is significant to understand that each electrical equipment parts have a specific function to perform. The mechanism of the electrical devices might often be complicated.
