Air Break Switch (ABS) is a type of switchgear equipment used in electrical power switching applications. It is called an air break switch because it makes use of air as the dielectric medium to suppress the electric arc produced during the closing and opening of the switch.

What is Air Break Switch? A type of switch which uses an air-like dielectric & arc quenching medium is known as an air break switch. So the contacts of this switch will open within the air. This switch is reliable and very effective as compared to other switches.

Air break switches can be of two types. It can be operated manually using either a handle/ratchet mechanism or an insulated ‘hook stick’ made either of wood or fiberglass. Air break switches are designed for switching under load, but there is often a noticeable arc associated with switching.

An air break switch is a type of switch that makes use of air as a dielectric and arc quenching medium. The contacts of an air break switch open in the air. Here, the arcing problem produced while opening the switch is resolved with the help of compressed air.

Hubbell's air break substation switches are engineered to deliver exceptional performance and reliability in managing utility power systems. These switches are designed for optimal functionality in high-voltage environments, ensuring efficient power flow and system protection.

The switch whose contact open in the air and quenching of an arc achieve by compressed air, such type of switch is called an air break switch. The air acts as a dielectric medium for the air-break switch.

Sep 27, 2022 · The main air-break disconnecting switches in use are the vertical break, center side break, double side break, knee, and pantograph types. The type used by individual utilities is generally based on standard substation layout practices.

This specification covers the design, production, on-site testing, and supply of Air Break Switches with Polymer Insulators suitable for system voltages of 11 kV and 22 kV. The switches are designed to interrupt current flow in both fault and normal conditions.

Air switches are classified as air-break switches and isolators (or disconnect switches). The air-break switch has both the blade and the contact equipped with arcing horns. Arcing horns are pieces of metal between which the arc resulting from …

Reliable individual-operated air break disconnecting switches for safe and efficient power isolation. Engineered for durability and seamless performance.
