Terminal Blocks > Wire (Termination) Technology > Screw Clamp elmex Earth Terminal Blocks replace conventional bus-bar used for earthing. The structural design is such that the mounting rail not only has a mechanical but also an electrical function. Earthing is established through the foot which clamps directly onto the rail. Earthing Terminal Blocks are mounted on the same rail along with other terminal blocks. The conducting part is Brass with Nickel-Tin plating, providing a low resistance path. Moreover, the housing is a Green-Yellow combination in accordance with universally accepted colour code for earthing.
Terminal Blocks > Wire (Termination) Technology > Screw Clamp elmex Multi Level Terminals are the perfect solution where space is a constraint and high density wiring is needed. The compact design of these Terminals with 6 mm thickness allows double wiring density and reducing the total number of terminal blocks to half. KUDD4 terminal is specially recommended as its upper level is offset laterally by half of the terminal block pitch. This offers better accessibility to the lower connection screws and better visibility of the lower marking labels. KU2D4 terminal blocks with internally shorted versions are suitable for one input and three outputs. elmex three level terminal blocks can be used for high-density wiring and for wiring special equipments such as proximity sensors. DUSD4 has a special link attached to the middle and lower level to facilitate the interconnection between adjacent terminal blocks, DU3D4 and DUSD4. The negative and positive circuits can be easily bridged together and then connected to a power source with DU3D4 terminal.

Terminal Blocks > Wire (Termination) Technology > Screw Clamp Vibrations adversely affect terminal connection, causing loosening of conductors and consequent overheating of terminal blocks. elmex Terminal Blocks are therefore designed to be inherently resistant to vibrations in normal applications. However, high vibrations can arise due to vibration affected installation sites, such as installations in and around mines, proximity to heavy machine shop,forging/ die casting shops, cement/steel plants machinery, textile machines and so on. Special designs for high vibration applications are also preferred in some Power Projects, Power Distribution Centers, Motor Control Centers and Relay Control Panels. depending on proximity of vibration generating equipment. elmex Standard Screw Clamp design, with compression springs, provided under the clamp, offer a reliable solution for high vibration applications of Terminal Blocks. These are called "SPRING LOADED" terminal blocks. FEED THROUGH TYPE : KST 4UWS, KST 6WS, KULT 4, KULT 6, KULT 1 DISCONNECTING TYPES: KULTD 4WS, KULTD 6 The spring is assembled under compression, so that it engages firmly with the contact clamp. For inserting the conductor, clamping screws should be unscrewed and pressed, which results into pushing down the contact clamp against spring action and creates space for conductor insertion below the current bar. When the screw is tightened with specified tightening torque,the clamping part moves to cause gripping of conductor with current bar, as with normal clamping process, but in case of spring loaded design, the conductor is gripped with additional clamping force exerted by the compression spring from below the clamping part. Special design of the current bar with a recess is available to anchor the hook bladed cable lug, in the current bar. This provision creates conductor locking within terminal block once it is clamped, so that it cannot be pulled out accidentally. This design is presently available in types KULT 1, 4, 6 and KULTD 4, 6.
Terminal Blocks > Wire (Termination) Technology > Screw Clamp Applications in Control & Automation require fuse protection facility. elmex offers Terminal Blocks with built-in safety fuse levers. These Terminal Blocks accommodate a glass cartridge fuse of 5 mm x 20 mm, 5 mm x 25 mm or 6 mm x 32 mm size. The fuse holder is made of special grade phosphor bronze and hence offers low contact resistance. A solid brass link type DL4 in place of the fuse makes it possible to use it as a disconnection type terminal block. KUDDF4 is a fuse terminal and a standard terminal block (feed through) combined in one housing, giving cost, time and space economy. It occupies the space of one terminal block and works as a pair of terminal blocks - the upper tier with fuse protection. One terminal can be assigned to one pair of signals. An LED is provided for blown-fuse indication. Standard operating voltages can be selected from the range of D1=24 VDC, D2=48 VDC, D3=110 VDC, D4=220 VDC, D5=12 VDC, A1=110 VAC and A2=240 VAC.

Terminal Blocks > Wire (Termination) Technology > Screw Clamp elmex Plug & Socket type terminal PS 8M is developed for applications in semi-draw out type motor control circuits/feeders. The connection between plug & socket parts of the terminal is established by contact mechanism employing spring action that provides permanent high contact pressure with very low resistance to securely connect the plug pin with the socket. PS 8M terminals are stackable to facilitate termination with disconnecting facility, for multiple cables, depending on the application. This feature allows use of only required number of terminals for stacking. The draw-out feature of PS 8M makes it convenient choice for panels with modular constructions wherein separately wired modules or panels cab be connected with one another once they are completely wired internally. Such a modular design facilitates quick disconnection for test and maintenance.

Terminal Blocks > Wire (Termination) Technology > Screw Clamp A thermocouple is a bi-metallic junction ie a junction between two different metals that produces voltage related to temperature difference. Thermocouples are classified depending on different alloys used for different temperature ranges. Some of the thermocouple types are as ; 'K' Type : Chromel (Ni/Cr) + Alumel (Ni/Al) 'J' Type : Iron (Fe) + Constantan (Cu/Ni) 'T' Type : Copper (Cu) + Constantan (Cu/Ni) 'E' Type : Chromel (Ni/Cr) + Constantan (Cu/Ni) For temperature measuring requirement, wherein measuring point is far from the measuring instrument, intermediate connections have to be made for extending the path. For such application conventional type terminal blocks cannot be used to create the required extension, since current carrying parts are made of either copper or copper alloy which are different than the thermocouple metals or alloys as mentioned above. to overcome this problem thermocouple terminal blocks are employed. Thermocouple terminal blocks are constructed using the same type of metal / alloy as that of thermocouple intended for measuring temperature. Thermocouple terminal blocks are used in pairs. elmex offers thermocouple terminal blocks in all four types of thermocouples described above.
