RBA Assemblies

 

An RBA Assembly includes a dynamic brake transistor and resistors completely

 

 

 

 

 

assembled and mounted in a NEMA 1 enclosure. They are designed for EO and MO

 

 

 

 

 

controls. Select the RBA based on the voltage rating of the control and the dynamic

 

 

 

 

 

brake watt capacity required. Use Table A-3 to select the RBA assembly. If more than

 

 

 

 

 

4,000 watts of brake capacity is required, use a combination of RTA (DB transistor) and

 

 

 

 

 

RGA (DB resistor) assemblies. Refer to Section 3 “Optional Dynamic Brake Hardware”

 

 

 

 

 

for wiring diagram.
