SUE3000 1VCF750090R0804

ABB SUE3000 is a high-speed transfer system/device (HSTS) for medium-voltage switchgear. It rapidly transfers critical loads from a failed or degraded incoming supply to an alternative supply to maintain process continuity. ABB identifies the SUE3000 as a high-speed transfer device, not a PLC, servo drive, or general-purpose DC power supply.

Part-number identification
The exact code 1VCF750090R0804 is most consistently associated with the SUE3000 HSTS HMI/front-panel assembly, although reseller listings are inconsistent and may describe it generically as the complete transfer device. It should therefore be verified from the nameplate, cabinet position, and ABB project BOM before ordering.

Item Identification
ABB system SUE3000
System function High-speed power-source transfer
Likely item represented by this code HMI / operator front panel
Installation Door-mounted on the medium-voltage switchgear cabinet
Purpose Local status display, configuration, diagnostics, and manual transfer commands
System components SUE3000 transfer device, REF 542plus protection relays, VM1-T high-speed vacuum circuit breakers, and voltage/current sensors
System performance
With suitable high-speed vacuum circuit breakers, the SUE3000 system can achieve transfer in approximately 30 ms, or about 1.5 cycles. It supports typical two-incomer/one-bus or two-bus-section-and-coupler arrangements.

The transfer logic evaluates source voltage, frequency, phase angle, residual voltage, breaker status, and related permissive signals before issuing the transfer command. Actual transfer time depends on the selected transfer mode, breaker operating time, protection settings, and the configured switchgear topology.

Ordering caution
Do not substitute this item based only on the SUE3000 family name. Confirm:

Whether the required item is the HMI panel, core transfer controller, or complete HSTS package.

The full code, including the final revision characters.

HMI display/interface revision and cabinet cutout.

Auxiliary supply and communication interface.

Compatibility with the installed SUE3000 firmware and configuration software.

Whether the application uses REF 542plus relays and VM1-T breakers.

Several online listings incorrectly classify this number as a medium-voltage drive, servo module, DC power supply, or ACS800 control board. Those descriptions conflict with ABB’s SUE3000 product family and should be treated as unreliable.
