Brake resistors must comply with specific requirements to meet the high-quality demands set by Siemens. Due to their intrinsic safety, high pulse loading capacity with a controlled surface temperature, and the compact, high-quality construction, KOCH resistors optimally fulfil these requirements. In addition, KOCH offers quick response times, absolute delivery reliability, and particularly short delivery times specifically for Siemens. Since there is a lack of space in the control cabinet in a large number of applications, the need for resistors in a substructure frame was recognized and implemented. This customer-specific solution makes it possible to mount fitting resistors for the SIMANICS G portfolio between the inverter and the control cabinet panel in a space-saving way. They can also be mounted on a hat rail clamp. This not only saves space in the control cabinet, but also saves time.
