Baldor still uses the control transformer fuses. All of these fuses should be locally available. There are 2 types of fuses. The large power fuses are in the fuse holder mounted on the panel. There are two

brands available, Buss and Gould. The second type of fuse is a single fuse for the control power transformer.

D Braking Contactor

Over a 15 year period several brands of contactors have been used. They are available locally. Baldor may stock a simular contactor. To check, get the part number of the existing device.

E Replacement SCRs/Diode and power cells

Sizes 0-3: The SCR and Diode are in the same package. Size 0, 1 and 2 are mounted in the module. The SCR/Diode in the size 4 are separate.

General Purpose/Ramp Up - Ramp Down

and non UL Versions of Multipurpose Control

The General Purpose (G controls) and the Ramp Up / Ramp Down (R controls) are no longer available. However, some parts are still available.

The first Multipurpose Softstarter used the same parts as the G and R controls except for the module. The current Multipurpose product line has a complete spare parts list in the manual.

A Control Module

The Control Module is no longer available. The Multipurpose module can be used as a replacement. For sizes 0, 1, 2 (G and R controls), a replacement control is required. For sizes 4-7 and D-J a replacement module can be used. For 60Hz applications use the MB8X, and for 50Hz applications use the MB9X. A conversion manual is included with each Multipurpose module.

B Circuit Breakers

The Circuit breakers used were Westinghouse and later on Square D. Baldor no longer stocks these breakers and we no longer have an OEM buying agreement from these manufactures. Westinghouse and Square D breakers should be locally available.

C Overload Relays

There were several brands of overload relays used in the G, R and M controls. If a new heater is required for the starter contact your team with the control size, the motor AMPS and the brand of overload that is installed.

D Relays

The plug in relays in the controls are very standard and are available locally. Baldor does stock most of the relays. It is common for relays to be added to controls by the end users.

To determine if the relays are available from Baldor. The following information is required.:

• What is the coil voltage of the relay?

• What is the number of pins or blades in the bottom of the relay?

• Are there pins or blades coming from the bottom of the relay?

• Is there a part number on the relay?

See catalog MN805.

F Current Calibrators

The G and R modules require a current calibrator. The current calibrator is nothing more than a resistor that sets the current during starting. If the user needs to change this resistor (current calibrator). Contact your team with the motor current and the control size.

J CT (Current Transformers)

There are two CT’s on some controls; a small one – CT1, and a larger doughnut type – CT2.

CT1 - CT6K1 (used on G and R sizes 3-7, M sizes D - J).

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.

Cross Over Chart

To convert an Old Style General Purpose, Ramp Up/Down, or Non UL Style Multipurpose, use the chart below. The last digits remain the same. The Multipurpose Soft Starter will be in a larger enclosure than the old control.
