cgm
.800 is designed and constructed to
withstand at least the thermal and dynamic eff ects of an arc
of 16 kA for 0.5 seconds should a defect result in an internal
arc in the gas compartment. The system conducts the gases
generated in a fully controlled manner to avoid any possible
injury to people in the equipment operation area.
Optionally
, a chimney can be positioned in the rear
of the cubicle to redirect the gases to the top section.
