– Fully type tested at CPRI
– Ex-Stock Availability
– Compact breakers suitable for 600 mm width Switchgear panels
– Suitable for Floor – Type, cassette type & RMU type panels
– Suitable for retrofitting
– A Compact, Light, Weight construction, Optimized to give minimum weight to KA ratio.
– Superior mechanical endurance limit Maintenance required only after 10,000 operations.
– A Unique ‘U’ shaped insulation barrier housing for the Vaccum interrupters, imparting maximum mechanical strength against electrodynamic forces and provides most effective phase to phase and phase to earth segregation.
– A screw type racking arrangement for easy insertion and withdrawl of the Circuit Breaker renders perfect contact pressure, independent of operator’s force
– A simple motor charged spring operating mechanism noted for its high performance reliability.
– A versatile mechanism capable of operating Vacuum Interrupters of any type . Hence, dependence on single source of Vacuum interrputers eliminated.
– Trip free mechanism suitable for repeated auto reclosing duty.
– Spring Charging time of less than 10 seconds.
– Totally enclosed construction for spring charging motor.
– Easy visual check of contact erosion.
