Connector type M

Connector type M

BS 546 standard connector for 15, 5 and 2 amps.
The 15-A variant is referred to as type M denotes the 5 and 2-A variant as type D .

The connector type M is an electrical connector that is mainly used in South Africa. It is the only connector type in Lesotho and Swaziland .

In Great Britain the plug has been replaced by type G plug . Type M is referred to as 15-A 3-pin in the old British standard BS 546 . The connector type D also comes from this standard. There was also a 10-A variant of the type M, but this was replaced by the 15-A variant. The connector type M is standardized in India under the designation IA16A3.

The distance between the pins is not ³ ⁄ ₄ "(19 mm), but 1" (25.4 mm). The earth is offset by 1 ¹ ⁄ ₈ ″ (28.6 mm). An adapter is therefore essential for Euro plugs or other plugs.

construction

Outer conductor , neutral conductor and protective conductor are designed as contact pins of the plug. The protective conductor provides reverse polarity protection .

The contact pins for the outer conductor and neutral conductor have a distance of 25.4 mm, a diameter of 7.06 mm and a length of 18.94 mm. The contact pin for the protective conductor has a diameter of 8.71 mm and a length of 28.89 mm.
