The majority of manufacturers now make 'Arc Resistant' versions of their switchgear.
The main concept of this switchgear is to prevent build up of the pressure from an arc fault. The main method to do this is to build in a duct and vent system into the switchgear to direct the hot gases away from the front of the switchgear.
It will also include structural design to withstand the arc energy and facilities such as racking with the door closed and full closure to prevent damage to neighbouring cubicles.
Be aware where vents are fitted if this kind of switchgear is installed indoors. It's no good venting off the gases up into a roof that then reflects them back down towards the operator.
