The portable three-phase short-circuiting device with quick automatic phase clamps (type CAR) is used on spherical coupling points permanently mounted on flat busbars in medium-voltage switchgear.
The quick automatic phase clamp has an extruded aluminium-alloy body and a quick clamping screw with a bayonet coupling at one end for connection to the insulating stick.
