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 recognised 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.

A​dvantages:

• space saving
• quick mounting with hat rail clamp
• compact design
• protection class up to IP65*
• highly impulse secure
• low inductance
• intrinsically safe under persistent overloads

*Test conditions: Water jet from nozzle with an inner diameter of 6.3mm, volume flow 12.5l/min +/- 5%, water pressure in accordance with the volume flow, distance 2.5-3m, test duration 3min

**(the intrinsically safety is usually given with 4 time of permanent type power)
