Legacy Circuit Breakers
The VSI and VTD oil circuit breakers, manufactured between 1963 and 1990, and the VMV vacuum circuit breaker introduced in 1990, are predecessors to the BSR. The VMV circuit breaker was a direct replacement for the VSI/VTD, utilizing vacuum interrupter technology for improved safety and durability.
