KAUTZ Starkstrom-Anlagen

What KAUTZ Starkstrom-Anlagen does

KAUTZ Starkstrom-Anlagen GmbH is a privately held, family-owned German manufacturer of bespoke electrical switchgear and power distribution systems, founded in 1985 and headquartered in Trier, Germany. The company designs and produces custom low-voltage (LV) and medium-voltage (MV) switchgear systems, anchored by its proprietary MODUL-K-SYSTEM (available in 630 A to 6300 A configurations, including the space-saving MODUL-K-425 variant) and the ARC-K optical/current-sensing arc-fault protection system. Products are metal-clad, arc-fault resistant, and certified to IEC/DIN EN 62271-200 and DIN EN 61439, with each system individually engineered by small teams of 3-5 people rather than produced as standard catalog items.

The company serves a diversified industrial customer base across chemicals and plastics (e.g., LANXESS), energy infrastructure (e.g., GRIDNOVA), sports/arena facilities (Veltins Arena), data centers, automotive, pharmaceuticals, steel, food and beverage, and wood/cellulose sectors. Its business model combines one-time custom-engineered switchgear sales with full installation and commissioning services and recurring maintenance contracts, including a 24/7 emergency service hotline. Revenue is generated exclusively via direct enterprise field sales, with KAUTZ engaged from early project planning stages through turnkey execution, using premium components sourced from tier-1 partners including Siemens, ABB, Schneider Electric, Danfoss, Phoenix Contact, and DEHN. Operations span approximately 75 bilingual employees across its Trier facility and a Luxembourg sister company established in 1993, with the company currently investing in production hall renovations as part of its 40th anniversary.
