How can circuit breakers withstand an earthquake?

Christian Cingolani, Global Product Marketing Manager LTB

ABB's answer

An earthquake damper will increase the damping of the natural oscillation of the circuit breaker. In this way the amplification of earthquake stresses due to resonance is significantly decreased, and the maximum mechanical stress on the circuit breaker significantly reduced.
