IEC 60144: LV Switchgear Enclosure Protection — The Predecessor of the IP Code System

LV Switchgear Enclosure Protection — The Predecessor of the IP Code System

IEC 60144 was the early standard for enclosure protection degrees for low-voltage switchgear and controlgear — later superseded by IEC 60529 (the famous IP code). While IP65/IP67 codes come from IEC 60529, the fundamental concept — using two digits for solid-object and water protection — was established in IEC 60144.
