CEE Overview

Industrial products are different from the ones found in your household. They have the ability to support higher
currents and voltages. This is why industrial plugs and sockets are suitable for use in polyphase systems with
high currents. They are also ideal for use in scenarios where you need protection from environmental hazards.
Industrial outlets have several important supporting features. They have weatherproof covers or waterproof
sleeves. Some industrial sockets come interlocked with a switch. This switch will help from accidentally
disconnecting when connected to an energized plug. Besides, some industrial connectors are approved for use
in “high-risk” areas, for example, in places like petrochemical plants and coal mines. These places have
flammable gases, which can pose a threat.
The CEE Form, or the CEEForm, stands for Certification of Electrotechnical Equipment. This is a certificate issued
for electrical products, and useful to trade electrical products globally.
The best-known CEE standards are the CEE 7, CEE 13, CEE 17, and CEE 22.
1. The CEE 7 is the standard used for household plugs and sockets.
2. The CEE 13 is the standard used for cables and cords.
3 The CEE17 is the standard used for industrial plugs and sockets.
Today, the CEE 17 is known as the IEC 60309 (formerly called the IEC 309). This is an international standard
governed by the International Electrotechnical Commission (IEC). The IEC 60309 regulates industrial plugs,
sockets, outlets, and couplers. In Europe, industrial connectors are made to the IEC 60309 standard. Various
other criteria based on IEC 60309 include the BS EN 60309-2 and the BS 4343.
Usage scenarios for different industrial plug and socket models:
Industrial plug: This is similar to the plugs in the electrical equipment of our households. Used for any type of
sockets.
Industrial Connector: This is a movable socket used in extended power supplies. They are suitable for portable
use too.
Wall-Mounted Industrial Socket: This is mounted on walls and equipment surfaces. The wires that connect to this
socket are on the wall and the device’s body.
Panel Mounted Industrial Socket: Typically used for cabinets or equipment. The user will fix the main body of this
product on the surface. And the wiring inside the equipment or panel is not visible.
Angled Mounted Industrial Socket: This socket has a similar function to the panel-mounted ones. But the
significant difference is the socket and the panel of the concealed inclined seat are angled. It does not have a
typical 90-degree angle.
Reverse Industrial Plug: This is a fixed plug. You can expect only connectors to work with it. This reverse plug is
divided into the panel and wall-mounted plugs. The installation form of the plug is similar to the one on the
socket.
