DAS Company is an authorized Klemsan distribution partner, stocking and supplying the complete Klemsan industrial connection portfolio — AVK screw terminal blocks (1.5–240 mm²), spring clamp and practical spring clamp terminal series, MPB lever wire connectors, 6 mm slim DIN-rail relays (24V DC / 230V AC), thermocouple terminal blocks (Type J and K), high-current terminals, DIN-rail interface modules and cable marking systems — to panel builders, electrical contractors and machine manufacturers across Europe from our Bulgaria distribution base.
Klemsan Elektrik Elektronik San. ve Tic. A.Ş., founded in Istanbul, Turkey in 1972, is one of Europe's established terminal block manufacturers with over 50 years of DIN-rail connection technology history and international approvals across all major industrial markets — including CE (Europe), UL (North America), GL (marine) and CCC (China). Klemsan exports to more than 80 countries with a comprehensive product catalogue covering over 5,000 SKUs across screw, spring clamp, lever and bolt connection technologies. Klemsan's compliance with IEC 60947-7-1 (terminal blocks for copper conductors), EN 45545-2 (railway fire performance) and UL 508 (industrial control panels) covers the most demanding European project specifications in industrial automation, rail, marine and process applications. Klemsan offers a cross-reference substitution for Phoenix Contact, Weidmüller and WAGO terminal block series in applications where European brand pricing exceeds project budget — providing IEC-certified quality at competitive pricing from a 50-year European market-supplied manufacturer.
The Klemsan AVK series is the core DIN-rail screw terminal block family covering feed-through, disconnect, fuse and earth terminal functions from 1.5 mm² to 240 mm² conductor cross-section. The AVK 2.5 (2.5 mm², 24A, 6.2 mm wide), AVK 4 (4 mm², 32A), AVK 6 (6 mm², 41A), AVK 10 (10 mm², 57A), AVK 16 and AVK 35 cover the standard industrial panel wiring cross-sections — all with consistent terminal block width ratios that minimise DIN-rail space consumption versus conductor cross-section. The AVK 50 and AVK 70 high-current terminals (125A and 160A) cover busbar connections, main distribution panel incoming feeds and transformer secondary terminations. All AVK terminals accept cross-connection jumpers, test sockets, bridge connectors and marking accessories within the same series — enabling consistent panel design across the full cross-section range. The AVK-TK disconnect terminal variant provides knife-type circuit isolation via a screwdriver-operated disconnect insert — enabling maintenance isolation of individual circuits without removing conductors from the terminal. Fixing screws are standard across all AVK terminals for enhanced DIN-rail mounting security in vibration applications including railway rolling stock and industrial machinery.
Klemsan's spring clamp terminal block series uses stainless steel spring technology to press the conductor directly against the current bar without a clamping screw — providing a vibration-proof, maintenance-free connection that does not loosen under thermal cycling or mechanical vibration. The stainless steel spring increases contact force proportionally as the conductor is pulled — making the spring clamp connection more reliable over time than screw connection under vibration loading. The Practical Spring Clamp (PSC) system extends the spring clamp principle with a tool-free push-in mechanism — the conductor is inserted directly without opening the spring with a screwdriver, and is released by pressing a push-in lever. The PSC system is compatible with fine-stranded, stranded and rigid conductors without ferrules — reducing conductor preparation time in high-density panel wiring. Both spring systems comply with IEC 60947-7-1 and are available across the AVK cross-section range for screw-to-spring conversion within the same housing geometry and DIN-rail footprint.
The Klemsan MPB series lever wire connectors (2, 3 and 5 position) provide tool-free conductor splicing and distribution for single-conductor connections in junction box, panel feed-through and lighting circuit applications — the direct IEC-compliant alternative to wire nuts in European installations. The orange lever mechanism opens the contact, the conductor inserts to the depth mark, and the lever closes — securing solid, stranded and fine-stranded conductors from 0.5 mm² to 4 mm² without tools and without ferrules. The MPB series covers HOT, Neutral and Earth conductor joining, cross-connection between parallel circuits and signal distribution at panel entry points — providing a faster, more reliable and more compact joint than wire nut or chocolate block connections. A fixing foot on the MPB housing enables mounting to standard surfaces inside junction boxes and trunking when the connectors need to be secured against movement.
The Klemsan 6 mm slim DIN-rail relay provides 1CO (SPDT) contacts rated 6A in a 6 mm wide DIN-rail housing with coil voltages in 12V DC, 24V DC, 120V AC and 230V AC — directly substituting Finder Series 34, Phoenix Contact REL-MR and Schrack MSR relay series in high-density relay panels. The relay body snaps into and out of the DIN-rail socket by pressing a black side lever — enabling relay replacement without removing socket wiring, reducing maintenance time significantly in relay panels with intermittent relay failures. LED coil activity indicator is standard across all voltage variants. The slim 6 mm profile allows up to 16 relays per 100 mm of DIN-rail — approximately 30% higher relay density than standard 17.5 mm pitch relays, directly reducing panel enclosure width for relay-intensive control applications.
Klemsan thermocouple terminal blocks (Type J iron-constantan and Type K chromel-alumel) provide DIN-rail mounting compensation junction connection for thermocouple extension cable at the panel entry point — using the correct thermocouple alloy contact material to eliminate the parasitic junction voltage that standard copper terminal blocks introduce into the thermocouple circuit. The unique feature of the Klemsan thermocouple terminal is a 4 mm test socket at the top — allowing a multimeter to be plugged in directly to read the process temperature or inject an analogue signal for loop calibration without disconnecting the thermocouple extension cable from the terminal block. Type J terminals (black marking) and Type K terminals (green marking) use colour coding that matches IEC 60584-3 thermocouple extension cable colour standards for immediate visual identification in mixed thermocouple-type panels.
Klemsan's plotter labelling system produces printed terminal block markers, cable markers and panel labels from a standard PC via the Klemsan marking software — generating marker text from imported component lists, PLC I/O allocation tables or manual entry. Snap-in marker holders on all AVK terminal series accept Klemsan printed marking strips without adhesive — providing permanent, clean identification that does not peel or discolour over the terminal block service life. Self-adhesive cable markers, heat-shrink sleeve markers and tie-on cable labels cover the full range of conductor and cable OD identification requirements in panel wiring and field cable installation. All Klemsan marking materials are UV-stable and rated for -40°C to +90°C continuous temperature — ensuring marking legibility throughout the terminal block service life.
