Isolators are completely essential for the safety of all electrical equipment and the people who operate it. Isolators are, first and foremost, a protection system. It ensures that the circuit has been de-energized to inspect and maintain it safely. Many people believe that an isolator and an MCB accomplish the same thing. While that assertion seems to be right, the functions of MCBs and isolators are vastly different. Under normal circumstances, MCBs may be used to cut the power to the whole circuit.
The MCB may trip in such situations, such as a short circuit or a power overload, to stop the flow of current into the circuit and save the appliances, but it is still dangerous to contact the MCB because it may be charged with a large amount of static charge. Isolators come to the rescue in this situation. When the isolator is closed, any residual charge in the circuit is grounded, making the circuit safe to operate and inspect for damage.

Types of Isolators
According to Their Application:
- Three loads of post insulators make up a double break form of the isolator. A tubular touch can be made straight by a spin on the middle insulator. The middle insulator’s rotation is regulated by a lever mechanism at the bottom of the insulator; it is also linked to the isolator’s manual operation (operating handle) by a mechanical knot rod.
- The arm interaction is divided into two components in a single break type isolator. Male contact is held by the first arm contact, while female contact is held by the second arm contact. Since the insulator on which the arm contacts are fixed rotates, the arm contacts change.
The rotations of the post insulators remain in reverse, allowing it to close the isolator by closing the arm contact. Insulators counter-rotate to open the arm link, and an isolator rotates into an off position. The motor-driven isolator is typically used in an emergency, but a manually operated isolator is also available.
- The pantograph-style isolator allows for current switchgear installation and takes up the least amount of space. There are post insulators and working insulators among these insulators.
- MCB Isolator– These are used in domestic scale wiring and low-power commercial establishments to provide security. As a result, they’re perfect for use in houses, small offices, and apartment complexes. MCB isolators are available in single-pole, double-pole, triple-pole, and four-pole configurations, much like MCBs.

Application of Isolators
Isolators Can be Used in the Following Ways:
- Transformers and high-voltage circuit breakers are examples of high-voltage devices.
- To avoid reckless use, these are shielded by a protection mechanism.
- When a substation fault occurs, the isolator isolates a section of the substation.
- For maintenance and protection, they are used to de-energize a circuit/part of a circuit.
Miniature Circuit Breakers and Isolators are somewhat similar and can be easily confused. The primary distinction between the two devices is that the MCB is an automatic switch that protects against overloads and short circuits.
Isolators are manually operated switches that are used to de-energize a section of a circuit for repair or operation.
