Load break isolators, also known as load break switches, are electrical devices used to isolate a section of a power distribution network from the rest of the system. They are designed to interrupt the flow of current in a circuit, allowing for the safe isolation of equipment for maintenance or repair. Load break isolators are commonly used in medium voltage applications, typically between 3.3 kV and 36 kV. Load break isolators consist of a switch mechanism that is enclosed in a housing made of insulating material. The switch mechanism is operated manually or electrically, and when it is closed, it allows current to flow through the circuit. When the switch is opened, the circuit is broken, and the load is isolated from the power source. Load break isolators are designed to operate under load, meaning that they can interrupt current flow even when the circuit is carrying a significant amount of current. Load break isolators are an essential component of power distribution networks, as they provide a means of isolating equipment for maintenance or repair without having to shut down the entire system. They are commonly used in conjunction with other protective devices, such as fuses or circuit breakers, to ensure that the system remains safe and reliable.
