Load Break Switch

Product Details:

• The 11 kV/22 kV Load break switches are manufactured suitable for mounting in sheet steel
• enclosure. The PCESAIR type load break switch offers a simple and compact construction
• with epoxy insulators, double switch blades, forged contacts with arc quenching chamber,
• lagging pin and loop less current path. The Nylon/FRP insulation makes the switch light
• weight with greater electrical safety and mechanical strength. LBS Panel is available in free
• standing Indoor/Outdoor type and RMU type configurations.
• The main frame is welded steel structure and the contacts are mounted on epoxy insulators.
• The upper fixed contact houses the arc quenching chamber and the connection terminal. Theswitch is also equipped with spring-assisted mechanism due to which constant speed is achieved during opening and closing operation. The switch is also provided with stored energy tripping device.

• Compact and reliable design.
• Rated SC making capacity up to 20 kA (RMS) 50 kA (PEAK) and make/break up to 630A.
• Tripping initiation by means of fuses.
• The dry type arc quenching chambers join two switch principle for safe disconnections of heavy and small current.
• Nylon/FRP insulation provides lighter weight, greater electrical safety and higher mechanical strength to the switch.
• Optional Mechanically interlocked earth switch.
• Suitable for Capacitor bank current switching.

Product Details:

• Best available option for protecting transformers up to 1000kVA in Indoor and Outdoor versions
• Fuse-trip mechanism which eliminates single-phasing
• Complete safety with Earth Switch interlocked with main switch
• Suitable for Capacitor Bank Switching
• On-load/Off-load Isolators are available.
• Electrical tripping through shunt coil (optional)
• ype tested for 11kV,630A,25kA and 22kV,630A,25kA
