TYPE L / EXPLAINED
How to recognize Type L
Type L is the easily recognized three-in-a-row system. The middle pin is earth. The 10 A version has smaller pins and a narrower overall spacing than the 16 A version, so the two should be shown and specified as different configurations.
- Common regions
- Italy, Chile and selected other markets
- Contact arrangement
- Three round pins in one straight line
- Common current variants
- 10 A and 16 A versions
- Typical supply voltage
- Usually 220–240 V
- Standard family
- Italian national system, including CEI 23-50
- Socket accepts
- Matching L variant; suitable C plugs in compatible 10 A sockets
Earthing, compatibility & common mix-ups
Italian bipasso sockets are specifically designed to accept both L sizes. A combination socket must not be confused with a single-size Type L socket. Some installations also offer Schuko connections, but that does not make a basic Type L socket compatible with every European plug.
What the type letter tells you
The letter describes a recognizable connection family. It does not specify the complete wall plate, mounting box, shutters, terminal design or approval for a destination market. A plug's rated voltage is also different from the actual supply voltage at a location. An adapter changes the physical connection; it does not convert voltage or frequency.
Choosing a Type L socket for your market
Start with the destination country and the appliance connection you need to support. Then identify the exact national version within Italian national system, including CEI 23-50, its marked current and voltage, and its earthing arrangement. The figures above describe common configurations; the supplied product's marking and technical documents define the actual model.
- Compare the complete contact pattern with the reference image, including the earth contact.
- Confirm the local supply voltage and frequency against the appliance input label.
- For a buying enquiry, include mounting format, current variant, quantity and required market documents.
Does physical fit mean the connection is suitable?
No. The earth connection, contact pressure, current rating, supply voltage and approved configuration all matter. Do not force a plug into a socket or remove an earth contact.
