Adaptation sets are additional equipment allowing the use of circuit breakers in the older generation devices. Thanks to them, there is the possibility of replacing the older generation switching apparatus with modern vacuum circuit breakers - e²BRAVO. Adaptation set in the form of the trolley allows the use of new circuit breakers in old-type switchgears such as: WRS, RSW, GIPO. Circuit breaker e²BRAVO can be adapted as a movable module for switchgear type RD1. It is fully compatible with earlier solutions and maintains full functionality of its predecessors.
