ABB ASFC-01C 64649540

The ABB ASFC-01C (64649540) is a switch-fuse controller designed for ABB ACS800 multidrive systems. It is an installation accessory used in drive power circuits to support fuse monitoring and switching-related control functions.

ABB identifies the product as “ASFC-01C; SWITCH FUSE CONTR ASFC-01C” and lists it for use in ACS800-107 multidrive installations. The original part has been superseded by the BSFC-01C, part number 3AXD50000006072.

Technical Parameters

The electrical ratings above are reported in product listings and should be checked against the nameplate and applicable drive documentation before installation.

Product Features

• Switch-fuse control: Supports switching and fuse-monitoring functions in compatible ACS800 multidrive installations.

• Charging-circuit supervision: Helps monitor relevant charging-circuit conditions.

• Control signal processing: Interfaces with the drive system's associated control and switching components.

• Industrial integration: Designed for use within the corresponding ABB multidrive cabinet.

• Defined replacement path: ABB identifies BSFC-01C as the successor to the original ASFC-01C.

Hardware Composition

The ASFC-01C is a dedicated controller assembly incorporating electronic control circuitry, electrical connection points, and switching-control interfaces. Depending on the circuit configuration, its functional sections support supply monitoring, charging-current supervision, and control of associated switching devices.

Refer to the original wiring diagrams for terminal assignments and the precise circuit configuration.

Application Fields

1. ABB ACS800-107 multidrive systems.

2. Industrial inverter cabinets with controlled charging circuits.

3. Fuse-status monitoring and charging-circuit supervision.

4. Maintenance and repair of legacy ABB multidrive equipment.

5. Industrial motor-drive installations requiring the specified switch-fuse controller.

ABB's product documentation lists the ASFC-01C among the spare parts used in multiple ACS800-107 drive configurations.

Maintenance Considerations

• Confirm the part number 64649540 and model ASFC-01C before ordering.

• Check the auxiliary supply and connected circuit ratings against the applicable manual.

• Inspect wiring, connectors, and switching components for signs of overheating or damage.

• Investigate external charging-circuit or fuse faults before replacing the controller.

• Follow electrical isolation and stored-energy discharge procedures before servicing.

• When replacing the original unit with BSFC-01C, verify the replacement instructions and system compatibility.

Conclusion

The ABB ASFC-01C 64649540 is a switch-fuse controller for compatible ABB ACS800 multidrive systems. It supports charging-circuit supervision and switching-related control functions in industrial drive installations.
