What Electrical Engineering Janssen does

Elektrotechnik Janssen GmbH is a privately held German electrical engineering services company founded on July 1, 1967 by master electrician Heinrich Janßen and headquartered in Nordenham, Lower Saxony. The firm operates five integrated service lines: switchgear manufacturing (Schaltanlagenbau), industrial services (Industrieservice), network technology (Netzwerktechnik), automation technology (Automatisierungstechnik), and crane services (Kranservice). It serves industrial customers primarily in the Wesermarsch region and Northern Germany, with notable international project work in Hamburg, Rotterdam (Netherlands), and Gent (Belgium). Disclosed customers include port operators HHLA and APM Terminals, titanium dioxide producer Kronos Titan, zinc smelter Nordenhamer Zinkhütte, aerospace manufacturer Premium AEROTEC, refiners PCK Raffinerie and DSD NOELL, and cable manufacturer Norddeutsche Seekabelwerke.

The company's technical capabilities include custom switchgear construction using Eplan P8 for design, cable calculation software, and Sistema for functional safety calculations; PLC/SPS programming on S5 and S7 systems; WinCC visualization for process control; fiber optic cable installation, splicing, and OTDR-based testing; and medium voltage assemblies for crane and industrial applications. It holds DIN EN ISO 9001:2015 certification (maintained since 1996) and SCC** Contractor Safety Certificate (held since August 2010, currently SCC** VAZ 2021), qualifying it for safety-critical industrial and port infrastructure work. The firm operates within a consortium model alongside ABB Sweden (general contractor providing crane-control programming IP) and Hans Künz GmbH (Austrian crane manufacturer) to deliver large international port crane projects.

The business generates revenue primarily through project-based, quote-driven contracts for professional services (industrial maintenance, crane installation and commissioning, automation engineering) and one-off or short-series switchgear manufacturing. Distribution is direct via enterprise field sales targeting industrial customers, with minimal digital marketing presence limited to a German-language website and social media channels. The firm employs 48 people including 7 apprentices, is led by three managing directors (Michael Janssen, Peter Dindas, Christian Diekmann), and operates with no disclosed external investors, parent company, funding rounds, or M&A activity.

Expansion highlights4 records

Broad incumbents

• Rittal GmbH & Co. KG: Large German manufacturer of enclosures, power distribution and climate-control solutions widely used in industrial switchgear. Competes indirectly by supplying the standard enclosures and pre-engineered cabinets into which Janssen integrates its custom switchgear builds.
• Siemens AG: Global industrial-electrification and automation incumbent whose SIMOCODE, SIRIUS, S7 PLC and WinCC platforms sit at the core of Janssen's automation work. Competes broadly for turnkey industrial-electrical and port-automation contracts and could absorb some of Janssen's service scope at scale.
• ABB AG (Germany): Global electrification and automation giant with a German subsidiary covering switchgear, drives and crane controls. Overlaps with Janssen on industrial switchgear and is also a consortium partner (ABB Sweden) for crane projects, making it both collaborator and broader-market competitor.
• Schneider Electric GmbH: Major multinational in energy management and industrial automation with deep switchgear and process-control portfolios. Overlaps with Janssen across switchgear manufacturing, industrial services and crane/terminal electrification.

Regional players

• Hans Künz GmbH: Austrian crane manufacturer and Janssen's consortium partner for new crane projects. Comparable in port-crane electrification scope; primarily a mechanical-crane supplier but delivers complementary electrical content alongside partners like Janssen.

Direct peers

• Hensel Electric GmbH: German Mittelstand manufacturer of low-voltage switchgear, distribution boards and enclosures for industrial and infrastructure applications. Directly comparable as a regional switchgear specialist competing for similar industrial and infrastructure contracts.
• Schaltbau Group: German manufacturer of switchgear, power-conversion and electromechanical components for rail, industrial and port applications. Directly comparable in switchgear and industrial electrical equipment, with overlap on crane/port electrification use cases.
• Stöwer Elektrotechnik GmbH & Co. KG: Northern German industrial electrical contractor offering switchgear construction, automation and industrial services comparable to Elektrotechnik Janssen's full service portfolio, serving overlapping industrial customer segments.
• KBR GmbH: German manufacturer of energy distribution systems, switchgear cabinets and building-services electrical engineering. Comparable in custom switchgear manufacturing and on-site electrical installation for industrial customers.
• Kries GmbH: German specialist in switchgear, power distribution and earthing systems with a strong industrial and energy-utility customer base. Comparable as a Mittelstand switchgear manufacturer competing for similar industrial electrical contracts.
