KRAH is your worldwide
partner for
electrical resistors
in the industrial sector
Whether it is plant engineering or power electronics, medical or power engineering, logistics, machine construction or equipment and plant engineering, we supply the right resistor solution. Our pulse-resistant power resistors, for example, have been especially designed for use as braking resistors or charging and discharging resistors and have proven their worth millions of times over in servo controllers, frequency converters and inverters. Resistors from KRAH also meet special requirements, for example in terms of high-voltage resistance, power consumption capacity or IP protection class, which is required when used under difficult conditions such as on oil platforms or in wind turbines.
KRAH customers benefit from our global presence, our IATF 16949-certified quality management system and our decades of experience as a development partner to customers from a wide range of industries. Do you need a customized resistor solution for your application? Then we look forward to hearing from you! Our engineers will work closely with you to develop the right resistor for your product using a tried-and-tested, reliable process that culminates in your customized solution.

Transport and Logistics
A smooth supply of goods requires highly available systems and equipment, both in procurement and in production. The flow of goods is increasing and must arrive at their destination faster than ever. As a result, the demands on infrastructure is also increasing; e.g. higher speeds in conveyor systems require more efficient braking resistors. The particularly impulse-resistant power resistors of the KRAH Group have been specially designed for use as braking, charging and discharging resistors.
KRAH power resistors prove their worth every day in these systems:
• Dynamic storage systems
• E-stacking truck
• Conveyor belts
• Crane technology
• Shipbuilding
• Railroad engineering
