This page lists the most frequently purchased electrical and industrial automation components by B2B customers at DAS Company — system integrators, panel builders, OEM machine manufacturers and industrial maintenance teams across Europe. Every product here earns its place through real order frequency, not promotional placement: these are the components that engineers and procurement teams order repeatedly because they work, they arrive on time and they are always available.
Our best-selling categories span miniature circuit breakers (MCB) and MCCBs, variable frequency drives (VFD), PLC controllers, industrial sensors (inductive, photoelectric, safety), DIN-rail terminal blocks and power supplies, AC contactors and motor starters, relay sockets and interface modules, cable management and industrial connectors — all stocked in our Bulgaria distribution base for same-week dispatch to addresses across Europe.
The industrial automation and electrical markets produce thousands of products every year. Only a fraction prove themselves reliable enough and accessible enough to become the default specification across hundreds of engineering projects. Our best sellers share four characteristics: IEC and CE certification for direct use in European industrial and commercial electrical installations; immediate stock availability from our Bulgaria warehouse without factory lead times; consistent field performance verified by repeat orders from customers who have already installed and commissioned them; and competitive B2B pricing that makes them the rational first choice when project budgets are reviewed.
Circuit breakers (MCB and MCCB) are the highest-volume category at DAS Company — the components that appear in every distribution board, motor control centre and panel assembly regardless of the industry. Our most frequently ordered MCBs include ABB S200, Schneider Electric DX3, Siemens 5SL, CHINT NXB and Himel H3 series in B and C curves from 6A to 63A. MCCB best sellers include ABB Tmax, Schneider DPX3 and CHINT NM8 for main distribution and motor protection from 16A to 630A.
Variable frequency drives (VFD/inverter) are the second largest category — ordered in volume by panel builders and system integrators for pump, fan, conveyor and general machine speed control. Best-selling drives include Danfoss VLT FC102 and FC302, Siemens SINAMICS G120, ABB ACS580, Mitsubishi FR-E800 and LS Electric G100, covering power ranges from 0.37 kW to 110 kW for the most common machine applications.
Terminal blocks and DIN-rail accessories are the steady, high-volume backbone of panel assembly supply — Phoenix Contact PT Push-In, WAGO 221 splicing connectors, WAGO TOPJOB S, Weidmüller W-Series and Klemsan AVK are the most ordered references. Relay sockets (Finder Series 40 and 55, Schrack RT, Relpol R15), power supplies (Phoenix Contact QUINT, WAGO EPSITRON, Siemens SITOP) and cable markers are consistently in the top sellers for panel builder B2B accounts.
Industrial sensors — including inductive proximity sensors from Omron E2E, Telemecanique XS and SICK IME, photoelectric sensors from Banner Q45 and SICK WTB, and safety light curtains from Omron F3SG and SICK microScan3 — represent the field-level automation components that machine builders specify repeatedly across machine generations.
AC contactors and motor protection from Schneider Electric TeSys Deca, Siemens SIRIUS 3RT, ABB A-series and LS Electric GMC are top sellers for motor control panel assemblies from 9A to 630A. Motor protective circuit breakers and thermal overload relays complete the motor starter assembly and are stocked across the full current range.
Every product in the best sellers list is supplied as an authorised distribution partner — genuine manufacturer products with full warranty, factory certification documentation and IEC compliance records. Our brand portfolio includes ABB, Schneider Electric, Siemens, Phoenix Contact, WAGO, Eaton, Legrand, Weidmüller, Omron, SICK, Danfoss, Mitsubishi Electric, Allen-Bradley, LS Electric, Hensel, CHINT, Himel, Relpol, Klemsan and more than 60 additional authorised brands. B2B customers consolidate procurement of multiple brands through a single DAS Company account — reducing purchase order volume, supplier management overhead and delivery coordination complexity.
All best-selling items are stocked at our Bulgaria distribution facility for fast dispatch to customers across Europe. Panel builders ordering mid-week receive components before the end of the working week in most European destinations. For project-based orders requiring larger quantities of specific components — full distribution board MCB sets, motor control panel contactor and overload relay kits, or complete cable management bills of materials — our team prepares project quotes with confirmed stock levels and delivery programme before order placement, eliminating the lead time uncertainty that disrupts panel production schedules.
Best-selling products carry competitive standard B2B pricing. Volume pricing is available for quantities above standard order thresholds — typically 10+ units for drives, 50+ units for MCBs and 100+ pieces for terminal blocks and connectors. Project pricing applies to complete bills of materials submitted for panel build or installation projects, regardless of quantity per line. Account pricing is available for panel builders and system integrators with ongoing procurement programmes — establishing agreed price lists for regularly ordered references that eliminate the need for quotation at each order. Contact our sales team to discuss account setup and pricing structure.
Unlike online-only distributors where selection is left entirely to the buyer, DAS Company provides pre-order technical support from engineers with application knowledge of the products we stock. If a requested MCB breaking capacity needs verification against your site fault level, if a VFD model needs confirmation for a specific motor type and fieldbus protocol, or if a sensor model needs checking for compatibility with your PLC's I/O specification — our team responds before the order is placed, not after the wrong component arrives on site. This service is available to all B2B accounts and is provided without charge as part of our standard customer support.
