The standard covers metal-enclosed LV power circuit breaker switchgear assemblies containing such devices as power circuit breakers, interrupting devices, switches and regulating equipment. It is also concerned with enclosed, rather than open, switchgear assemblies. For AC LV switchgear, the voltage is considered to be 1000 V and below, and for DC LV switchgear the voltage is considered to be 3200 V and below.<>
