SIEMENS 3RW4056-6BB45 145A AMP 100HP 230V-AC SOFT STARTER(Parts Only)

This versatile device offers intrinsic and motor overload protection with adjustable current limitation and external reset capabilities. However, it doesn't evaluate thermistor motor protection or include an inside-delta circuit. Additionally, it provides robust mechanical power output for three-phase motors, offering flexibility with adjustable motor current and continuous operating current at 40°C.
