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.

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.
*Test conditions: Water jet from nozzle 6.3 mm inside diameter, flow rate 12.5 l / min +/- 5%, water pressure according to volume flow, distance 2.5- 3m, test duration 3min.
**With fourfold type power and free convection. 1. no short-circuit, 2. no fault to frame, 3. self-extinguishing, 4. no melting of casing. Type power always corresponds to 35% duty cycle of the respective resistor type.
