Industrial trailing plug & connector types explained
Example of IP44 rated plug & connector
(Protection against objects above 1mm & protection against spraying water)
This IP rating perfect for mostly Indoor use. This example is of a 230volt plug & connector.
We use high quality heavy duty industrial trailing plugs & connectors on all our Leads with crimped cable core ends for a secure connection.
Example of IP67 rated plug & connector
(Protection against dust & can temporary submersed in water up to a depth of 1 meter)
More expensive than the IP44 range but recommended for outdoor use. Some companies simply choose to use IP67 rated plugs & connectors
for the more secure bayonet type interlocking connection.
This is a example of a 230v plug & connector.
IP44 & IP67 industrial plugs/connectors can be interconnected if required.
Example of the two types of 3 phase UK plugs
Plug on the left is referenced as a 3phase+nuetral+earth (also known as a 5pin or 5pole)
Plug on right is referenced in our shop as 3phase & earth (also known as a 4pin or 4pole)
Example of 63amp plug with pilot pin
which in turn will provide a safe electrical interlock that will break first when the user disconnects or make last prior to separation of the phase pins,
other measures to prevent disconnection under load conditions can be done with a mechanical interlock on the distribution outlet
and normally high current electrical equipment will also have its own mechanical or electrical interlock built-in.
16amp, 32amp & 63amp 230volt plugs dimensions below
3pin = live, neutral & earth
3phase 16amp, 32amp & 63amp "4pin" plug types dimensions
4pin = 3 phases & earth only
3 phase 16amp, 32amp & 63amp "5pin"plug types dimensions
5pin = 3 phases, nuetral & earth
What is meant by the hour pin position?
Note: The actual clock position is determined by looking at the “connector “ from the front with the Keyway at the bottom.
The earth pin hr position is determined at connector or wall socket
