• – Cost effective breakers for Switchgear Panel Manufacturers

– 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
