Jan 1, 2025 · An isolator is a type of mechanical switch that is used to electrically isolate electrical circuits from current passing through them. Isolators are used to locally power on and power off machinery when needed for operation, fault finding, or maintenance work.

What is Electrical Isolator? The isolator can be defined as; it is one type of mechanical switch used to isolate a fraction of the electrical circuit when it is required. Isolator switches are used for opening an electrical circuit in the no-load condition. It is not proposed to be opened while current flows through the line.

Jun 10, 2024 · An electrical isolator is an electrical switch that disconnects one part of an electric circuit from another and provides a visible separation at the point of isolation. It is a mechanical switch and is also known as a disconnector switch.

Apr 25, 2019 · An electrical isolator which is commonly known as an isolator or disconnector is a piece of equipment that is used in electric devices and power systems with the main function of effectively isolating two different parts of an instrument. By definition, isolation is the process of complete separation of various parts of an apparatus and this ...

Dec 21, 2024 · Isolator may be defined as a mechanical switch which isolates a part of the circuit from the system as and when required. Electrical isolators separate a part of the system from rest for safe maintenance works. Isolators are used to open a circuit under no load.

Mar 15, 2013 · Isolator Definition: An isolator in electrical systems is a manually operated mechanical switch that separates a part of the circuit for safe maintenance. Purpose: The main purpose of an isolator is to ensure safety by isolating a …

An Electrical Isolator, also known as a disconnector, is a manual mechanical switch used to disconnect electrical equipment from the power system. Unlike circuit breakers, isolators operate under no-load conditions and do not have arc-extinguishing mechanisms.

Jan 30, 2023 · Isolators or disconnectors work by physically separating sections of a circuit - this is called an air break. Fused switch disconnectors provide an additional level of safety and certainty because these will blow, breaking the circuit, in the event of rogue current. What are Isolators and Switch Disconnectors Used for?

Oct 21, 2018 · Isolation refers to the process of completely disconnecting an electrical circuit or equipment from the power supply to ensure safety during maintenance or troubleshooting. It guarantees that no electrical current or voltage is present in the isolated section of the system.

An electrical isolator is a switching device that isolates or protects a circuit. Mainly, these switches are used in the distribution of electrical power. However, there is much more to know about these switches.
