Safety clearances
During a short-circuit interruption, high temperatures, ionized gases and high pressures
occur in and above the arcing chambers of the circuit breaker.
Safety clearances are required to:
●
allow the pressure to be distributed
●
prevent fire or damage caused by any escaped ionized gases
●
prevent a short circuit to grounded sections
●
prevent arcing or short-circuit currents to live sections
