What E T A Circuit Breakers does
E T A Circuit Breakers (legal entity E-T-A Elektrotechnische Apparate GmbH) is a privately held German industrial components manufacturer founded in 1948 and headquartered in Altdorf near Nuremberg. The company designs and manufactures circuit protection devices — thermal, thermal-magnetic, hydraulic-magnetic, and magnetic circuit breakers — alongside electronic overcurrent protectors, solid-state relays and remote power controllers, switch-mode power supplies, and integrated intelligent power distribution platforms under the ControlPlex®, REX, SCS® Smart Control Systems, and PowerPlex® brand families. Technical differentiation rests on broad DC 24V overcurrent-protection expertise, multi-protocol industrial Ethernet and fieldbus support (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP/RTU, PROFIBUS-DP, IO-Link), CAN-based vehicle protocols (CANopen, SAE J1939, CAN 2.0B), patented plug-in click connection technology, and extensive hazardous-location and automotive type approvals (ATEX, IEC 60079, UL 2367/508/1310/121201, CSA, KBA, ECE R10).
The company generates revenue almost exclusively through hardware sales across six product streams: circuit breakers and electromechanical protection devices, electronic overcurrent protection systems, intelligent power distribution systems, relays and SSRPCs, custom design solutions, and switch-mode power supplies. It monetises through a direct enterprise sales motion augmented by a four-facility production network, ten wholly-owned subsidiaries, and a representative network covering more than 60 countries, with customer-account applications distinguishing Wholesale, Distributor, End User, and Project buyer types. Pricing is quote-based and not publicly disclosed; standard terms offer 30-day credit accounts and pro-forma prepayment.
E-T-A serves four principal vertical segments. Mobility & Transport (trucks, buses, automotive, construction/agricultural/forestry machinery, recreational vehicles, specialty vehicles, marine, rail) and Industry & Production (automotive manufacturing, intralogistics, mechanical engineering, process and control technology) are stated as primary; Telecommunications & Datacom and Medical & Equipment Technology (medical devices, professional tools, industrial equipment control, commercial kitchen appliances) are secondary. Named reference customers span Sumitomo (automotive), Horsch (agricultural machinery), Dethleffs (recreational vehicles), Nokia (telecommunications infrastructure), Simrad (marine electronics), Meyn Food Processing (food processing automation), and German machine builders Hans Weber Maschinenfabrik and Gebr. Heller Maschinenfabrik — indicating enterprise sales rather than SMB concentration. The company is managed by three Managing Directors (Ralf Dietrich, Christian Kube, Dr Jennifer Sell) with William Stewart identified as an additional managing-director-level leader in the UK market.

E T A Circuit Breakers product offering
Product offeringCore offering
E-T-A designs and manufactures circuit breakers for the protection of equipment, including thermal, thermal-magnetic, hydraulic-magnetic, magnetic, and electronic overcurrent protection devices for DC and AC applications. The company also sells intelligent power distribution systems (ControlPlex® Rack, Board, DIN Rail), the REX System, PowerPlex®, and SCS® Smart Control Systems for industrial automation and vehicle electrification.
Product overview
E-T-A offers the world's most comprehensive product portfolio for overcurrent protection, power distribution, circuit breakers for equipment protection, power and solid state relays, and intelligent complete systems. The product architecture follows a platform-plus-modules approach centered around three main intelligent power distribution platforms: ControlPlex® (comprising Rack, Board, and DIN Rail variants), SCS® Smart Control Systems for vehicle applications, and the REX System for compact all-in-one power management. Supporting these platforms are specialized modules including CPC12/CPC20 bus controllers, power supply modules (EM12-T, EM12D-T), potential distribution modules (PM12-T), electronic circuit protectors (ESX300-S), and solid state relays (ESR10). The ControlPlex® family provides industrial automation solutions with communication via PROFINET, EtherNet/IP, EtherCAT, Modbus TCP/RTU, and IO-Link protocols, while SCS® Systems serve vehicle electrification with CAN-based communication. The REX System integrates power supply, bus controller, overcurrent protection, and power distribution in a modular design achieving 60% space savings, and the E-BOX extends this concept for recreational vehicle applications.
