SK-R1-MCB1-PF755 Allen Bradley PowerFlex 755 Main Control Board Kit IP20
SK-R1-MCB1-PF755 is a motion circuit breaker kit from the Allen-Bradley brand, a Rockwell Automation company, specifically designed for the Kinetix 5700 multi-axis servo drive system. This kit integrates short-circuit protection and ground fault detection, providing branch circuit protection for the servo motor power cable, and complies with NEC (National Electrical Code) and IEC 60204-1 mechanical electrical safety standards. Through its modular design and plug-and-play installation, the SK-R1-MCB1-PF755 significantly simplifies the electrical cabinet layout of multi-axis servo systems, reduces field wiring work, and is an indispensable protection component for building high-performance, high-safety servo control systems.
Typical Application Scenarios
Multi-axis synchronous control in packaging machinery.
Application: High-speed food and beverage packaging machine (12-axis linkage).
Solution:Each Kinetix 5700 driver (e.g., 2198-S160-ERS) is equipped with 4 sets of SK-R1-MCB1-PF755, protecting the forming, filling, sealing, and labeling motors respectively. Ground fault protection prevents water splashing during cleaning from causing motor insulation degradation. Modular design allows for non-stop replacement of faulty axes, improving OEE by 8%.
