K Control Transformers
Control Transformers are locally available. Baldor stocks simular transformers byt may require panel modification to fit.
L Bypass Contactors
The bypass used for G and R controls have varied during the years. Currently Baldor is using ASEA or ABB contactors which were used for several years of production of the G, R and M controls. The ASEA/ABB contactors are normally stocked by Baldor. If the contactor is not a ASEA/ABB Baldor does not stock replacements. A replacement should be found locally.
