Features
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.
Auxiliary contacts
All these switches can be attached with 2NO+2NC 15 Amps switches.
Motor-driven-types available
The standard versions are for stick operation. Motor-driven versions are also available. For further details please contact FUJI.
