N Brazilian plug

Three round pins in a hexagonal recess – Brazil and newer buildings in South Africa.

Standard: IEC 60906-1, NBR 14136, SANS 164-2
Current: 10/20 A
Voltage: 100–240 V
Earth: yes
Pins: 3

Type N is based on the international standard IEC 60906-1, designed in the 1980s as a common plug for the world. Brazil made it compulsory in 2011 (NBR 14136), and South Africa adopted it as SANS 164-2. The sockets are deeply recessed for safety and also accept Europlugs. Brazil uses two sizes: 10 A with 4 mm pins and 20 A with 4.8 mm pins.

What it looks like

Three round pins (4 or 4.8 mm): two 19 mm apart and an earth pin slightly off the line between them.

The drawings are schematic – they show the pin layout, not the exact dimensions of the standard.
