These applications are: Main switches according to IEC/EN 60204 respectively VDE0113 with interlocking device, terminal protection and restrective contacts. Switch disconnectors according to IEC/EN 60947-3 and VDE 0660 part 107 with break distance for 690V. Motor switches 3-pole or 4-pole; according to IEC/EN 60947­3 respectively VDE 0660 part 107, motor switches series LT are dimensioned for switching high rated current AC3 and AC23A. Main switches and Main switches with Emergency-Stop function According to standards IEC/EN60204 or VDE0113, all electrical equip-ment of industrial machines must be equipped with a main switch. This must permit disconnection of all the electrical equipment during cleaning, maintenance and repair work, and other extended periods when it is stationary. In case of two or more main switches, an interlock system must be used. It is recommended to use a multiple-pole main switch (cam switch). Main switches have to correspond to: a) Switch disconnector according to IEC/EN 60947-3 and VDE 0660 part 107 for utilization category AC23-B or DC-23B. b) Disconnectors are selected according to thermal rated current. They must possess a contact that ensures load switching via the contac-tors (see switching program A3-10). This contact must have a sufficient AC15 switching capacity. c) The interruption capacity of the switch must equal or exceed the locked rotor current of the largest motor plus the total current of all other electrical equipment in the circuit. Requirements: Interruption of the electrical equipment, with only on and off positions clearly marked with O and I. It must be lockable in the off setting. The line terminals of the main switch must be protected according to utilization category IP2X. Colour of handle black or grey. Main switches with Emergency-Off function are additional supplied with red handles and contrasting yellow escutcheon plates. 2 Technical data are subject to change without notice OLNECIKTSJAQËR D656E
