CLASSIFICATIONS
Class I
Device in which electrical safety is provided
by an additional protective conductor (earth)
connected to the metal frame of the lamp.
Class II
Device in which protection against electric shocks
is not provided solely by the basic insulation,
but which has additional safety measures such
as double or reinforced insulation.
These measures do not involve earthing devices
and do not depend on the installation conditions.
Class III
Device in which protection against electric shocks
is based on a safety extra-low voltage power
source and in which no voltages greater than
this can be generated.
A class III device does not need earth protection.
APPROVALS
ENEC certification of European conformity.
RATES
The diagrams shown in this catalogue
are expressed in millimetres.
IP DEGREE OF PROTECTION
Electrical fittings are designed to prevent
the intrusion and contact of solids and liquids
with live parts.
Resistance to the penetration of solids
and liquids is expressed by the acronym IP,
followed by two digits that show the degree
of protection: the first digit refers
to solid bodies, the second to liquids.
First digit
0 No protection.
1 Protected against the penetration
of solid bodies larger than 50 mm.
2 Protected against the penetration
of solid bodies larger than 12 mm.
3 Protected against the penetration
of solid bodies larger than 2.5 mm.
4 Protected against the penetration
of solid bodies larger than 1 mm.
5 Protected against dust.
6 Totally dust-tight.
Second digit
0 No protection.
1 Protected against dripping water.
2 Protected against dripping water
up to 15° from the vertical.
3 Protected against rain.
4 Protected against splashing water.
5 Protected against water jets.
6 Protected against waves.
7 Water-tight on immersion.
8 Water-tight on submersion.
