On the other hand, a circuit breaker has a high withstanding capacity as it can regulate currents, even high currents. It will catch fire if it’s used at the condition of on-load. Withstanding CapacityĪn isolator is an off-load device, which makes it have a low withstanding capacity to currents. But circuit breakers have the capacity to break load faults. Isolators are not used to break load faults. ApplicationĪnother isolator and circuit breaker difference is that isolators are used in industrial applications, while circuit breakers are used both in industrial and domestic settings.
Installation WayĪn isolator is installed on both sides of the circuit breaker, while a circuit breaker is installed in the circuit. While a circuit breaker is a single box that’s composed of an electromechanical switch and a relay it has an arc extinguishing system. ConstructionĪn isolator is a simple mechanical switch it does not have an arc extinguishing system. If there’s a fault, it cuts off the entire system. While a circuit breaker, on the other hand, is like an Automatic Circuit Breaker (ACB). This is also done for inspection and servicing purposes. Branded raw materials and an efficient quality system are utilized in the manufacturing process.Īn isolator’s major function is to cut out a section of the electrical system that has faults, so that it will be safe to repair.

A circuit breaker is very suitable for handling devices with heavy load currents, such as transformers.įor high-quality circuit breakers, Liyond, a professional circuit breaker supplier is the best choice. The arc extinguishing of a high voltage circuit breaker happens in a vacuum medium, which protects the electrical system more. It also has a built-in extinguishing system that makes it capable of interrupting high loads and faults. It can be operated manually and automatically. It’s used to control the flow of current.
The greater the fault intensity detected, the faster the power will be interrupted.Ī circuit breaker is like a fuse. A circuit breaker detects such defects and interrupts the circuit’s power flow, preventing further damage. Its primary role is to protect circuits from overload, faults, and short circuit failures. So, in the upcoming paragraphs of this post, we will be discussing the difference between isolator and circuit breaker.Ī circuit breaker is known as the heart of the electrical system it serves as a safety device. It’s very paramount that the debate of the isolator and mcb (miniature circuit breaker) is settled now so that you don’t mistake their functions and abilities. However, some differences exist between them. Both components have a similar function of disconnecting electrical circuits when there’s a load current issue. circuit breaker, and this is because they are closely related. There is usually a debate of isolator vs. They are cogent components in an electrical system. The importance of isolators, as well as circuit breakers, such as mv breakers cannot be overemphasized.
Amongst these components, isolators and circuit breakers are commonly found in every electrical installation. To ensure the safe operation of electrical equipment, measures must be put in place to make sure that there is no load current or load fault that can disrupt the smooth running of electricity.Ī very important set of components that helps to ensure this is switchgear components.
