MCC BUCKET
MCC Buckets – Motor Control Center Solutions
Overview
MCC Buckets (Motor Control Center Buckets) are modular, pre-engineered units used within Motor Control Centers to control and protect electric motors and other electrical loads. These buckets are designed for plug-in or draw-out installation, allowing quick maintenance, flexibility, and safe isolation without shutting down the entire MCC. Each bucket typically includes motor starters, circuit protection, control devices, and pre-wired terminal blocks, making them essential for efficient and scalable industrial motor control.
🔹 Key Features and Benefits
-
Modular Design: Enables quick installation, removal, or replacement without disturbing adjacent units.
-
Standardized & Custom Sizing: Available in standard 12", 18", and 24" widths — custom sizes are also available upon request to fit unique configurations.
-
Safety and Reliability: Built to meet NEMA ICS 18 or IEC standards, ensuring safe and consistent operation.
-
Network Integration: Available Smart MCC options with Ethernet/IP, Modbus, and Profibus communication.
-
Versatile Control: Supports manual, automatic, and smart control schemes including remote access and PLC integration.
🔸 Types of MCC Buckets
| Type | Description |
|---|---|
| Full Voltage Non-Reversing (FVNR) | Standard bucket for starting motors in a single direction. |
| Full Voltage Reversing (FVR) | Enables motors to run forward and reverse. |
| Soft Starter Bucket | Reduces inrush current and mechanical stress on motors during start-up. |
| VFD Bucket (Variable Frequency Drive) | Offers speed and torque control by varying voltage and frequency. |
| Feeder Bucket | Used for power distribution, not directly controlling motors. |
| Combination Starter | Combines a starter with a disconnect or circuit breaker and overload protection. |
| Lighting/Breaker Bucket | Designed for lighting loads or breaker-only applications. |
| Plug-in vs. Draw-out | Plug-in is fixed; draw-out allows easy maintenance without disconnecting wiring. |
