What Is a Square D Model 6 MCC Bucket?

Understanding MCC Buckets

In the world of motor control centers, a "bucket" refers to a self-contained plug-in unit that houses a circuit breaker, motor starter, or combination starter/breaker. The Square D Model 6 MCC uses a draw-out bucket design, meaning each bucket can be physically removed from the MCC section without de-energizing the entire panel. This modular design is one of the key features that makes the Model 6 so popular in industrial facilities.

Types of Square D Model 6 Buckets

Square D Model 6 MCC buckets come in several configurations, each designed for a specific application:

• Full-voltage non-reversing (FVNR) starters: The most common type, used to start and stop motors in one direction
• Full-voltage reversing (FVR) starters: Allow motor operation in both forward and reverse directions
• Combination starters: Include both a circuit breaker and a motor starter in a single bucket
• Feeder breaker buckets: Circuit breakers only, used to distribute power to sub-panels or equipment
• Solid-state soft starter buckets: Provide controlled motor acceleration to reduce mechanical stress
• VFD (variable frequency drive) buckets: Allow variable speed motor control

Standard Bucket Sizes

Square D Model 6 MCC buckets are sized by the ampacity of the circuit breaker or starter they contain. Common sizes include:

Bucket Size	Typical Motor HP	Secondary Market Value
30A combination starter	Up to 10 HP (480V)	$300 – $800
100A combination starter	Up to 30 HP (480V)	$500 – $1,500
200A combination starter	Up to 75 HP (480V)	$800 – $2,000
400A feeder breaker	N/A (feeder)	$1,200 – $3,500
800A feeder breaker	N/A (feeder)	$2,500 – $6,000

Why Square D Model 6 Buckets Have High Resale Value

The Square D Model 6 MCC has been installed in industrial facilities across North America for decades. Because the Model 6 is still widely in service, there is constant demand for replacement buckets from facilities that need to replace failed or obsolete units. This sustained demand keeps secondary market prices strong. A bucket that cost $3,000 new may still fetch $1,000 to $2,000 on the secondary market if it is in good condition.

Compatibility Considerations

Square D Model 6 buckets are designed to be interchangeable within the Model 6 system, but compatibility depends on the bus ampacity of the MCC section and the physical size of the bucket. Our buyers understand these compatibility requirements and can accurately assess the value of your specific bucket inventory.
