Integrated maintenance-free accumulator

SB accumulator
The accumulator is cast in the main body of the breaker, which offers a number of advantages.

First, the accumulator is well-protected from bangs and knocks.

Second, it is maintenance-free. The SB breakers feature a patented diaphragm support which reduces diaphragm distortion and wear.
