Load Break Switch
System Control offers a Load Break Switch. The 11 kV/22 kV load break switches are manufactured suitable for mounting on a panel. The load break switches are manufactured in two types – Sysair and Syscom. Sysair is snap action type, while Syscom is compressed air quenching type. The Sysair 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. The switch 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. Special features: compact and reliable design; rated SC making capacity up to 20 kA (RMS) 50 kA (Peak) and make/break up to 630 A; tripping initiation by means of fuses or relays; 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; and optional mechanically interlocked earth switch.
