ISO 11446 13 pin Electrical System
Since 2008, the growth of 13 pin systems has escalated and has now become a more or less standard option for most caravan owners.
Issues such as pin burnout and bad pin contact which affected the 12S socket system has been virtually eradicated by the change over to 13 pin. The 13 pin system in generally accepted use, is that as described in ISO 11446. This design is the most widespread throughout Europe.
On balance, the ISO 13 pin is the 'safest' type of connection currently available between the towing vehicle and towed vehicle. There are some very good advantages for the 13 pin over the continued use of 12N/12S systems. These include:
With the change to 13 pin now firmly in place, there will always be the need for 'adaptor sets' to interface the different connections between the car and caravan.
Right Connections has a wide and varied range of adaptors so please visit this page on our website.
