11 3K, 3KE, 3LD Switch Disconnectors 3LD Main and EMERGENCY-STOP Switches up to 125 General data Design Construction of the contacts Each switch has three adjacent contact elements 1). fourth leading contact element for switching the neutral conductor, a continuous PE/ground terminal, an auxiliary switch (1 NO or 1 NC) can be fitted to each side of the switch. The auxiliary switches operate as leading contacts on opening. On opening, the make contact opens before the main contacts, so that a contactor carries the switching capacity in the circuit and the maintenance or safety switch switches at zero current. On closing, the auxiliary switch switches later than or at the same time as the main contacts. Switch construction Construction of rotary operating mechanisms The rotary operating mechanisms of the switches for front or floor mounting are mounted on control cabinet doors, front panels or side panels with four-hole or center-hole mounting with a standard diameter of 22.5 mm and operated from the outside. In their Off position, they can be locked with up to three padlocks with a hasp thickness of 8 mm. Controls with defeatable doorcoupling rotary operating mechanism are available in addition. Switch position indicator: The switch position is clearly marked with direction arrows and an "O" for OFF and a "I" for ON at the front. Switches for front mounting: The switches for front mounting are connected directly to the rotary operating mechanism through the fixing screws or - in the case of center-hole mounting - a special-purpose coupling. Switches for floor mounting: The switches for floor mounting are snapped onto 35 mm standard mounting rails according to EN or screw-mounted on mounting plates. 3LD TK5 switch for front mounting with rotary operating mechanism 3LD UK01 3-pole changeover switch for front mounting with selector switch 3LD TK1 switch for front mounting with selector switch 3LD VK53 6-pole switch for front mounting with rotary operating mechanism The actuators are connected to the lower section of the switch through a door coupling, which can be released in its zero position, and a 300 mm long switch shaft. When the control cabinet door is open, the switch can be protected against inadvertent operation by removing the switch shaft from the lower section of the switch. The mounting depth can be adapted to individual requirements by adjusting the switch shaft length. 1) 16 versions have four contact elements; 3-pole changeover switches and 6-pole main control switches have six contact elements. Switches for distribution board mounting: The switches for distribution board mounting are suited for operation in switchboards and for switching inside control cabinets or distributors. They have cap and mounting dimensions to DIN and can be fitted under the same cover together with miniature circuit breakers. The selector switches can be locked in their OFF position with up to 2 padlocks with a hasp thickness of 6 mm. Switches in molded-plastic enclosure: For surface mounting of individual main control and EMERGENCY-STOP switches, molded plastic-enclosed switches to degree of protection IP65 are used. The actuators can be locked in their OFF position with three padlocks with a hasp thickness of 8 mm. The molded-plastic enclosures each contain an N and/or a PE/ground terminal. 3LD TK5 switch for floor mounting with rotary operating mechanism and defeatable door coupling 3LD TB5 switch in moldedplastic enclosure 3LD TK11 switch for distribution board mounting with selector switch 3LD2 2-1TL13 switch for floor mounting with rotary operating mechanism and defeatable door coupling Siemens LV 1 T 2008 /11

Version "" stands for "open-circuit principle", version "R" for closedcircuit principle" (see schematic circuit diagram on page /44). If a fuse is tripped, a green LED signal flashes (general fault) and the location of the failed fuse is indicated by a red LED. Using more than one device facilitates identification of the affected branch circuit. The EF monitor is automatically reset to the standby position once the faulty fuses are replaced. This state is indicated visually by the status display (green LED). The EF monitor is also suitable for operation in industrial networks badly afflicted by harmonics. /32 Siemens LV 1 T 2008

The size 00 for 160, 3-pole switchable in-line fuse switch disconnectors are available for 100 mm busbar center-to-center clearance and only as a special version for 185 mm busbar center-to-center clearance. Instead of one size 1 to 3 in-line fuse switch disconnector, two size 00 disconnectors with an adapter and masking frame can be used (see ccessories) on a 185-mm busbar system. The swiveling mechanism with 3-pole switchable disconnectors of sizes 1 to 3 is lockable and ensures simultaneous switching of all three phases. For size 4 the following versions are available in addition to the standard version: a slim version (W H = mm) a special version (W H = mm) (delivery possibilities on request). ll SENTRON 3NJ in-line fuse switch disconnectors are fed by way of the busbars. The outgoing current is transported by cable, see adjacent graphic "Terminal positions"). With SENTRON 3NJ41 in-line fuse switch disconnectors it is possible to choose between having the cable connection on top or on bottom (standard version) by turning the contact carrier. The upper part can be removed completely. This ensures easy mounting. Inspection holes For voltage testing, all SENTRON 3NJ in-line fuse switch disconnectors are fitted with voltage test apertures. Mounting position The SENTRON 3NJ in-line fuse switch disconnectors can be mounted vertically or horizontally. When mounted horizontally, however, system-specific reduction factors and the coincidence factor (DIN VDE 0660 Part ) according to the applicable system regulations must be observed. Integration ssembly kits as well as TT modules and partly equipped sideby-side cabinets are available for installation in the SIKUS 3200 (8GG) modular distribution board system; see Chapter "SIVCON Power Distribution Boards, Busway and Cubicle Systems" --> "Components for Distribution Systems". Installation in SIKUS Universal (8GF) is also possible. Please inquire. Siemens LV 1 T 2008 /45
