Isolator Switch

You can rest assured to buy Lixin Isolator Switch from our factory. An isolator switch, also known as an isolation switch, disconnect switch, or disconnecting means, is an electrical switch used to isolate or disconnect a circuit from its power source. Unlike circuit breakers or fuses, which are primarily designed to protect against overcurrent conditions, isolator switches are intended for maintenance, repair, or isolation of electrical equipment for safety purposes. Here are the key features and functions of isolator switches:

Isolation Function: The primary purpose of an isolator switch is to physically disconnect a circuit from its power source, effectively isolating it from the electrical supply. This isolation is essential for ensuring the safety of personnel working on or near the circuit.

Manual Operation: Isolator switches are typically manually operated, meaning they require physical intervention (such as flipping a handle or lever) to open or close the contacts. This manual operation allows personnel to control the isolation process directly.

Visible Status: Isolator switches often feature visible indicators, such as position markers or colored handles, to clearly indicate whether the switch is in the open (isolated) or closed (connected) position. This visibility helps prevent accidental contact with energized circuits.

Mechanical Interlocks: To prevent unsafe conditions, isolator switches may include mechanical interlocks that prevent them from being operated when the circuit is under load or when other safety precautions, such as lockout/tagout procedures, have not been followed.

High Current Ratings: Isolator switches are designed to handle high currents commonly found in industrial and commercial electrical systems. They are available in various sizes and configurations to accommodate different voltage and current ratings.

Durability and Reliability: Isolator switches are built to withstand the rigors of industrial environments, with robust construction and high-quality materials ensuring reliable operation over an extended lifespan.

Variants: There are different types of isolator switches designed for specific applications, including main switches for building distribution boards, motor isolators for controlling motors, and fused isolators that incorporate fuses for additional protection.

Compliance with Standards: Isolator switches must meet relevant safety standards and regulations to ensure their effectiveness in isolating electrical circuits safely. These standards may vary depending on the application and location.
