elmex Universal (TS32mm)DIN Rail Mounted Feed Through Terminals in Polyamide 66 Housing offers the complete range suitable for all control and power application. The proven spring clamp design offers high contact force and is easy to use. The range covers terminals for conductor sizes from 0.5 sq mm to 16 sq mm for spring clamp. The special foot design provides the slot for easy mounting and removal of a single terminal from the stack, using a screwdriver.
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.
While standard Screw Clamp or Spring Clamp terminal blocks are designed for direct connection of conductors, (solid, stranded, flexible), simply after stripping the insulation, there are other wiring practices and applications where conductors have to be provided with ring type or fork types lugs, for more secured connections. elmex has developed a whole range of Stud type terminal blocks with connection possibility from 0.5 sq mm to 16 sq mm, which accept ring/fork type lugged cables. These are available in both Polyamide 6.6 and in Melamine Housings. For Stud Type terminals KAT, studs have special long nuts, with a slot at the top, so that the nuts can be operated using screwdrivers. This facility of using screw-driver is very useful where space-constraints may not allow use of standard spanner for tightening. These nuts also serve as test sockets, in which pins of test wires can be plugged. These Stud Type terminals are used with protective transparent covers, which enclose the live parts, as protection against accidental contact. Such covers can be provided from a a stack of stud terminals. All the metal parts used are of brass (copper alloy) which make them suitable for use in applications like switch boards, switch yards, marshaling racks etc., generally exposed to environmental extremities.
Certain Application in Control and Mesearurement circuits necessiate locating operating faults quickly without disconnecting the conductors. elmex offers a range of disconnecting type terminal blocks which can be used to disconnect the continuity without actually removing the wires. DSDT 2.5 : These Terminal Blocks finds special application in control and instrumentation industry. The hinged knife edge lever can be easily pushed open to simulate faulty condition. The copper link and brass contacts are tin plated offering low contact resistance.
elmex offers a wide variety of Power / Bus-Bar / High Current Terminals suitable for all types of cables (solid, stranded, with fork type and ring type lugs) both in Polyamide 66 and Melamine Housing. In the Feed Through Range, Terminal types KUT25, 35, 50 and 95, with respective rated currents 101, 125, 150 and 232 Amps are available for connecting solid and stranded conductors. Power (Bus-Bar) Type terminal range covers DPBB50, 70 and 120, rated upto 269 Amps, for fork/ring type lugs, bolted to the current-bar of the terminal block. Protection and Safety For increased creepage distance and safety against accidental contact, partition plates / barrier plates are assembled along with the terminal block. Protective transparent covers are assembled at the slots provided on the barrier plates. This provisions make the assembly fully safe, while simultaneously offering open design of terminals for connection fork / ring lugged cables.

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.
