An air break switch consists of several parts such as an insulating base channel, stoppers, wire mesh, contact arm, stationary arcing horn, insulators, etc. These switches are generally used to open the electric circuit under load conditions. The arc produced during the switching process is quenched by compressed air.
LBS type air load break switch is available with 3.6kV or 7.2kV up to 600 Amps 3-pole and 3.6kV or 7.2kV with 200 & 400 Amps 3-pole including power fuse. This LBS air load break switch unit is attached with power fuses and is also a striker. This feature is not found in usual LBSs.
Excellent arc-extinguishing characteristics
The arc-extinguishing system uses a gas-cooling method. This results in less contact wear than that of comparable oil-immersed types, so ensuring a longer service life and lower maintenance costs.
Light and compact design
The load break switch and fuses are incorporated into one body and are ideally suited for H.V. cubicle or metalclad switchgear assembly applications.
High current-limiting power fuses
The LBS type is provided with FUJI power fuses so ensuring an accurate and uniform interrupting performance.
Economical first cost
The use of these fuses eliminates the need for circuit breakers with trip mechanisms, and so reduces initial installation costs.
Safe fuse replacement
Fuses can easily be replaced or changed to different ratings in perfect safety.
A shunt trip mechanism
A trip mechanism can be attached to LBS and LB having 100 and 200 Amps ratings. It can be tripped remotely.
Blown fuse indicator
LBS and LB200 to 400 Amps rated switches can be supplied with a blown indicator limit switch attached for remote indication use.
All these switches can be attached with 2NO+2NC 15 Amps switches.
The standard versions are for stick operation. Motor-driven versions are also available. For further details please contact DAYA.
Generally, load break switches have been developed in two types air-blast & SF6. There are three kinds of CBs available standard single-pole & double pole, ground fault circuit interrupter & arc fault circuit interrupter CBS. This switch mainly includes an arc extinguishing chamber, disconnect blade & operating mechanism.
