All of These STANDARDS govern appliances with rated which assures safe operation, even in the most operating voltage not exceeding 690 V, 500 Hz and adverse environmental conditions. rated current not exceeding 125 A, and are mainly designed for application in the manufacturing and VARIETIES AVAILABLE service industry, on building sites and similar uses. The range includes over 2,100 varieties of PLUGS and The main purpose of the STANDARDS is to prevent SOCKETS for portable or permanent connection in two accidental or deliberate mismating of PLUGS and mutually compatible series: connections which are not compatible in terms of EUREKA Series voltage, current, frequency, polarity and type of use, which comprises straight and 90 angled 16 A and 32 A which might therefore cause personal harm as well as PLUGS and connectors with protection degrees IP44 damage to the electric appliances which they connect.

INDUSTRIAL PLUGS and SOCKETS MAIN STANDARD REQUIREMENTS COLOUR CODE. The STANDARDS which govern the use of INDUSTRIAL The operating voltages are identified by conventional PLUGS and SOCKETS both for alternating current colours as shown in the table: (frequency up to 500 Hz) and for direct current, distinguish the two categories by operating voltage: Rated operating - Extra-Low Voltage PLUGS and SOCKETS voltage Colour 1).

Low voltage >50V. In low voltage > 50 V versions, the obstacle is provided by two elements: - a keyway (on the socket) with a matching key (on the plug). - a larger earth contact than the other contacts, situated in different clock-face positions depending on the characteristics of use.

8 When the socket is viewed from the front, the clock- face position (h) of the earth contact is found by taking as a REFERENCE the keyway, which is always situated at 6 o'clock. Extra-Low voltage <50V. In extra-low voltage < 50 V versions without earth contact, the obstacle is provided by two references: - the major consists of a keyway on the plug, matching a key on the socket, which is always situated at 6 o'clock;. - the minor also consists of a keyway (plug) and key (socket), but situated in different positions around the clock-face depending on the characteristics of use. Viewing the socket from the front, the clock-face position (h) of the minor keyway is found by taking as a REFERENCE the major keyway, which is always situated at 6 o'clock. Yellow: rated operating voltage between 100 and 130 V~. The 63 A and 125 A SOCKETS must be fitted with a pilot contact to activate an electrical interlock if required. Blue: rated operating voltage between 200 and 250 V~.
