UG 9256/804 is a MINISTART three-phase asynchronous-motor starter with automatic phase-sequence correction, motor protection and fixed soft start. The full current/voltage reference determines the usable motor range; the /807-specific mains-separation feature must remain distinct from /804.

Quick Verdict

Consider UG 9256/804 where the documented phase-correction and starting behavior fit the actual motor and load. Confirm the complete variant, current setting and required electrical protection; output phase sequence does not independently prove the mechanism turns in the intended direction.

Design and Build

The /804 is a defined variant, not a shorthand for every UG 9256 function. Its source page shares family information with /807, but the documented motor-terminal mains-separation feature belongs specifically to /807. Keep that distinction in the selection record. If the application needs that feature, review the qualified electrical design and the exact alternative before ordering.

Specify a motor starter with the actual motor, supply, rated current and installation conditions. Identify protective equipment, conductor selection and terminal access using the matching product instructions. A narrow module or family current range does not establish suitability for every motor or operating duty.

Configuration and Integration

Automatic phase correction addresses the electrical phase sequence at the motor terminals. The driven mechanism still needs an approved direction check because wiring, motor and transmission arrangement affect the physical result. Establish the required direction before operation and verify it through the machine procedure. Avoid treating the supplier's clockwise wording as a guarantee of every shaft or load orientation.

Define start, stop, reset and fault behavior in the machine control design. Match settings to the motor and the permitted duty, and preserve the accepted wiring and configuration. Control commands and ordinary diagnostic indications should not replace the equipment's separately required protective functions.

Applications and Use Cases

Evaluate UG 9256/804 for an identified three-phase motor installation with known supply, load and direction requirements. Confirm the complete starter reference and current setting.

Select and set the motor-current range for the actual nameplate and duty. The fixed soft-start behavior should be evaluated with the real load rather than assumed to provide arbitrary adjustable acceleration. Confirm phase-failure and overload reporting, reset and restoration. Preserve the complete variant and settings so a replacement can reproduce the accepted motor-control behavior.

The useful result is supported motor starting and stopping with the required load and diagnostics. Supply phase sequence, electrical output and physical mechanism direction are related but distinct checks. Evaluate the actual motor and driven equipment through the approved commissioning procedure.

Alternatives and Selection

Compare /804 and /807 against the same motor duty, phase-correction requirement and approved electrical design. Include separation features, protection, fixed start behavior, diagnostics and restoration.

Price and Value

Price: Request a quote. The quotation should identify the exact product configuration, included options, delivery terms and support scope. Accessories and integration work should be listed separately so the hardware price can be compared on a like-for-like basis. A family name or headline specification is not a complete purchasing description.

Assess value against the work the product enables in the machine. Include the engineering needed to configure it, the equipment that must operate alongside it and the effort required to maintain or replace it. A lower component price can be outweighed by extra integration work, while additional features are valuable only when the application can use them. Compare written configurations rather than assumed package contents.

Pros and Cons

Pros

Automatic phase correction addresses a defined supply-order requirement
Combined starting and motor-protection functions support an identified circuit
Compact starter arrangement supports a specified cabinet layout

Cons

Full current/voltage variant and settings require confirmation
Physical mechanism direction still needs verification
The /807-specific mains-separation feature is not assigned to /804

Who Should Consider DOLD UG 9256 804 Phase Correcting Motor Starter?

The strongest purchasing case is a clearly defined requirement that matches the documented configuration. If the project depends on a particular option, interface or mechanical arrangement, include it explicitly in the order. Keep the accepted configuration with the equipment documentation so a later replacement preserves the intended application.

Commissioning and Acceptance

Verify the configured motor current, required direction, start/stop behavior, fault reporting and permitted recovery with the real load through the approved electrical and machine procedure. Record exact hardware, settings and wiring. Reassess the arrangement after changing a motor, supply, load cycle or control interface.
