Frequently asked questions
Why do modular sockets follow local rules?
Sockets are “local” products, which must adhere to the standards
of the place where they are used. Over time, a large number of
standards was created, and this diversity has remained almost
unchanged to this day. An attempt to unify European sockets was
made in 1986 (IEC 60906-1), which ended without changes in
use being made in Europe but was partially adopted in Brazil and
South Africa.
How many socket standards are there? Is it possible that a
country uses more than one standard? In this case, how can I
choose the correct solution?
There are 13 socket standards, and in many countries more
than one standard is in use. Importation of equipment, such as
household electrical appliances, has often made it necessary to
install foreign standard sockets able to accommodate the plugs
this equipment is fitted with.
You can refer to the table in this brochure which gives all ABB
solutions for each country in order to ensure the correct use. To
guarantee maximum safety, ask to your ABB contact.
Why do modular sockets not have the CE mark?
ABB modular sockets are not “CE” marked as this is not required
by European Directive 2005/95/EC, which indicates (Annex II) that
products identified as “Domestic plugs and sockets” are out of the
scope of the european directive.
Modular sockets are included into this category and cannot,
therefore, receive the “CE” mark.
Why does the M1170 modular socket not carry any quality
mark?
This “dual” socket accommodates different types of plugs:
Europlug, Italian 10A/16A and the German Schuko. The shutters
for the pins of these plugs on the M1170 modular socket are
larger than the other socket models (M1173 and M1175, both
with quality markings) in order to accommodate each type of
plug. The product's geometry therefore makes conformity with
the different standards impossible, and as a consequence it is not
certified by the standards.
Why do the names of the connections change from socket to
socket?
Product marking indications are defined by the applicable product
standards. In table 1 you will find a summary of the markings for
each model.
Why do the rated current values change for each socket
model?
The rated currents of the sockets are defined by local standards.
In general, the current values fall between 10 A and 20 A. It
is always advisable to connect equipment with a high power
consumption using sockets rated at a minimum of 10 A.
Table 2 lists the voltage, current and maximum power supply for
each single-phase socket.
What are safety shutters and what kind of protection do they
offer?
These are insulating components located in front of the holes
for the plug pins (and therefore the socket's contacts); they
create a barrier between the accessible part of the socket and
the live parts. They create an obstacle to inserting objects which
could create a danger for untrained users: metal objects, wires,
screwdrivers etc.
Safety shutters are designed to open only when a plug is inserted,
therefore offering additional safety.
