What SET does
SET Selected Electronic Technologies GmbH is a privately held, family-owned German engineering company founded approximately 1988 and headquartered in Wedel, Schleswig-Holstein. The company develops and manufactures electronic protection devices and systems across three integrated domains: (1) high-voltage interference (HSB) solutions including Reihenschwingkreise (RSK) resonant circuits, thyristor Abgrenzeinheiten (TAK/TAC series), and capacitive Abgrenzeinheiten (CAE series) for protecting steel pipelines and personnel from dangerous touch voltages induced by AC power lines and railway traction systems; (2) cathodic corrosion protection (KKS) equipment including the PROTRONIC digital, PROLINE, and PROTRONIC 1/100–1/500 protection current devices; and (3) autonomous off-grid solar and hybrid power systems including the ISC Smart-Grid controller, COMET modular ~1kW solar unit, and Solar Medicus health-station package.
The company's core technology rests on proprietary hardware designs rated for 80,000–250,000+ hours of operation and a proprietary MAESTRO calculation software used for pipeline interference expert assessments. Generation 2020 product launches introduced higher current-handling capacity (up to 100 kA transient, 1400A short-term discharge). Revenue is generated through a mix of one-time hardware sales, professional services (expert reports/Gutachten, commissioning, and revision measurements per DVGW/EN/DIN/VDE standards), and recurring subscription revenue through the SET DATA-Portal for remote monitoring. Pricing is project-specific via direct quotation, with multi-year contract cadences on hardware deployments. The company serves enterprise customers globally — pipeline operators, utilities, energy companies, and telecommunications providers — through direct field sales from its Wedel headquarters, with devices deployed across Germany, Saudi Arabia, Indonesia, Latin America, and Austria.
SET maintains continuous ISO 9001 certification since 2011 and is currently developing two AI-enhanced R&D projects: MAESTRO21 (AI-augmented calculation software) and ARGUS-KI (predictive maintenance controller in cooperation with Fachhochschule Kiel, funded by Schleswig-Holstein state AI promotion). The business is led by Managing Directors Frederic Korupp (third-generation family) and Manel Callau Lopez, with Karl Korupp as Chairman of the Supervisory Board. No institutional investors, parent companies, or subsidiaries are disclosed.

SET competitors and assessment
Company assessmentBroad incumbents
- Siemens Energy: Global incumbent in T&D, grid protection, and substation equipment. Competes with SET on grid-side protection/relay technology and has substantially greater scale, R&D resources, and utility relationships.
- Schneider Electric: Global incumbent in energy management and industrial automation. Offers grid protection, power-quality, and asset-monitoring solutions that partially overlap with SET's HSB and KKS offerings.
- TE Connectivity (Raychem): Global incumbent offering cable protection, heat-shrink products, and energy/pipeline connection solutions via the Raychem brand. Broader portfolio but with overlapping pipeline-protection and electrical-infrastructure applications to SET.
- ABB: Global incumbent in electrification, motion, and process automation including grid protection relays and condition monitoring. Broad overlap with SET's protection and monitoring value proposition at much larger scale.
Direct peers
- Pepperl+Fuchs: German manufacturer of industrial sensors and intrinsic safety/condition-monitoring equipment. Comparable through its condition-monitoring and process-instrumentation portfolio addressing similar industrial and utility process-control use cases.
- Phoenix Contact: German manufacturer of industrial connection technology, automation, and electronic interface/condition-monitoring devices. Comparable in product breadth (industrial electronics, monitoring, surge protection) and mid-sized German industrial customer overlap.
- DEHN SE: German family-owned manufacturer of lightning protection, surge protection, and safety equipment for power systems. Directly comparable to SET's HSB portfolio of protection/limiting devices and to its German mid-market industrial customer base.
- Weidmüller: German specialist in industrial connectivity, power conditioning, and electronics for process and energy industries. Overlaps with SET on industrial electronic protection, monitoring, and condition-based solutions sold to utilities and pipeline operators.
Emerging players
- MATCOR: Specialist provider of cathodic protection products and services for pipelines and infrastructure. Direct overlap with SET's KKS (kathodischer Korrosionsschutz) product line and pipeline-operator customer segment.
