Descriptiontext

KRAH Gruppe is a privately held, family-owned German manufacturer of electrical resistors and electronic controllers, headquartered in Drolshagen, North Rhine-Westphalia, and founded in 1970. The group is the self-identified world market leader in power resistors for the automotive industry, operating approximately 2,000 employees across more than 15 development and production sites in Germany, Italy, Slovenia, the United States, Brazil, China, and India. Its core technology portfolio spans wire-wound power resistors (0.5 W to 70 kW) on ceramic, mica, and fiberglass carriers, ceramic PTC thermistor resistors, and electronic controllers (MPM, LPM, PWM, Relay Box) for HVAC and engine cooling fan management. The company serves automotive OEMs and Tier-1 suppliers as a Tier-2 component vendor, with growing exposure to e-mobility (precharge/discharge, on-board charger, and high-voltage coolant heating resistors) and industrial customers in automation, power electronics, medical, transport, and mechanical engineering.

KRAH generates revenue through direct B2B sales of engineered, often customer-co-developed components, with no public pricing or catalog channels and quote-based commercial terms. Go-to-market is enterprise field sales supported by an in-house engineering organisation and application specialists (e.g., Head of Sales Industry, Sales Manager E-Mobility), reinforced by participation in trade shows such as Battery Show Europe 2026 and a digital presence via the corporate website. The business is multi-segment: automotive remains the primary vertical, e-mobility is an explicit growth pillar with dedicated products and personnel, and industrial provides diversification across power engineering, automation, and transport and logistics. Quality and information security are central to the operating model, evidenced by IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, TISAX, and ODETTE certifications. The company has remained under founding-family ownership (Hermann family) since inception, with no external institutional investors identified.

Product overview1 text field

KRAH Gruppe is a world market leader in electrical resistors for the automotive industry, offering a comprehensive portfolio of power resistors (0.5W to 70kW), PTC resistors, and electronic controllers. The core product lines include Leistungswiderstände (Power Resistors) with various housing types (liquid-cooled, ceramic carrier, aluminium, steel/stainless steel, open coil), PTC-Widerstände (PTC Resistors with positive temperature coefficient), and Elektronische Regler (Electronic Controllers) including MPM, LPM, PWM, and Relay Box modules. The company also operates through its HKR Automotive subsidiary for automotive-specific solutions. The product range covers automotive applications (HVAC, engine cooling, ignition systems/NSR), e-mobility solutions (battery management precharge/discharge resistors, high voltage coolant heaters, on-board charger resistors), and industrial applications (automation, power engineering, equipment, transport/logistics). KRAH develops products jointly with customers from specification through research, development, and manufacturing.

Product and service3 records
1Power Resistors (Leistungswiderstände)
CategoryPower Resistors / Electrical Resistors
