Explore High-Quality Isolators for Safe Electrical Systems

Isolators are a crucial component to ensure optimum protection and a safe working environment. Polycab isolators are meticulously designed to offer a visible and reliable solution to physically separate a part of the electrical system from the power supply, thus preventing the flow of electricity and minimising the risk of electrical accidents. From single-phase to 3-phase isolators, Polycab offers a range that seamlessly caters to various requirements and applications.

Find the Best 4-Pole Isolators for Comprehensive Electrical Control

A 4-pole isolator comprises 3 poles that use the isolator while one remains neutral. This type of isolator switch is typically used in commercial or industrial applications that demand higher safety and protection levels. At Polycab, each 4-pole electrical isolator is meticulously engineered to provide isolation between the load and supply. These isolators comprise various features that ensure comprehensive electrical control. Let us take a glimpse at a few:

• Available in ampere ratings from 40A to 125A

• Real contact position indication for safety

• Large terminals with safety shutters

• Circuit label holder for easy identification

• Padlocking provision for added security

• Dual contact breaking mechanism for reliability

• Finger-proof terminals (IP20 rated)

• Bi-connect terminals on both sides for flexible wiring

• Airflow channels for improved ventilation

• 7-year warranty

• Bi-stable DIN-clip for easy installation

• Line load reversibility for versatility

Understanding Double Pole and Single Phase Isolators: Key Benefits

Single-phase or single-pole isolators are essentially designed for single-phase systems where power is supplied by a single line and a neutral conductor. These are frequently used in residential and small commercial applications where the electrical load is relatively low.

Double pole isolators, on the other hand, control two separate circuits, making it possible for you to isolate appliances safely. They are quite often used for appliances with heavy loads, such as a cooker or shower. The wires supplying electricity to double pole switches are typically larger than those used for single pole switches. Additionally, they serve as a safety shut-off for residential appliances.

Isolator - FAQs

What is an Isolator and Why is It Essential?

An isolator is a mechanical switch that is particularly designed to completely disconnect a portion of an electrical system from the power source for safety purposes. It does this by eliminating residual voltage or current. Used in both high- and low-voltage systems, it provides a visible break in the circuit. 

Unlike circuit breakers or fuses, an isolator does not trip automatically and must be operated under no-load conditions. It needs to be operated manually to disconnect or reconnect a circuit when the current flow is already interrupted by other protective devices like circuit breakers. An isolator is essential to ensure that no electrical current or voltage is present in the isolated part of the system. It helps protect the workers from electric shocks and prevents equipment damage.

What Are Electrical Isolators Used For?

Electrical isolators are used to provide safety and operational benefits in various industries and electrical systems, such as those in:

• Industrial manufacturing

• Railway and electrified transport

• Renewable energy systems

• Power generation plants

• High voltage substations

• Transmission and distribution networks

What Are the Advantages of Using a Double Pole Isolator?

The advantages of a double pole isolator include:

• It can withstand harsh operating conditions due to its robust construction, ensuring optimal performance.

• It is suitable for a wide range of applications, such as construction, manufacturing, energy, etc.

• It provides easy installation and operation benefits, making it a practical choice and a user-friendly solution for electrical isolation requirements.
