Siemens Furnas 89 - Breaker MCC Bucket - 100 A, 240 V, 9" Height, 3 P | AmpState

Designed for industrial motor control centers, the Siemens Furnas 89 Breaker MCC Bucket delivers reliable protection and seamless compatibility for 3‑pole systems. With a 100 A, 240 V rating and a compact 9" height, this MCC bucket slides into Siemens System 89 MCC assemblies as a direct replacement for OEM parts and retrofit projects.

Key features and benefits

• Direct OEM replacement — specifically engineered for Siemens System 89 MCC systems, enabling fast swaps with minimal wiring adjustments.
• 3‑pole configuration at 100 A, 240 V — robust protection for three‑phase motors and feeders, supporting demanding industrial loads while preserving electrical safety margins.
• Compact 9" height — fits neatly into standard Siemens System 89 enclosures and control cabinets, helping to optimize panel real estate.
• Protocol‑aware compatibility — designed to integrate smoothly with existing motor control infrastructure, reducing integration risk during retrofits or upgrades.
• Reliable AmpState supply — sourced through AmpState with global delivery, ensuring availability for maintenance, downtime planning, and spare parts inventories.

Ideal use cases

• Retrofits: replace aging MCC buckets in existing Siemens System 89 installations to restore peak performance without redesigning the control scheme.
• New installations: incorporate into new builds or expansions that leverage Siemens System 89 motor control centers for standardized, scalable protection.
• Maintenance programs: keep as a trusted spare to minimize commissioning time and downtime when a bucket needs replacement.

Why this MCC bucket stands out

What sets this unit apart is its precise fit and purpose-built design for Siemens System 89. It’s not a generic add‑on; it’s a purpose‑built component that aligns with Siemens’ architecture, ensuring consistent electrical performance and mechanical compatibility. By choosing this 100 A, 240 V, 3‑pole bucket, maintenance teams reduce risk during swaps, preserve wiring layouts, and maintain the integrity of the motor control scheme across the facility.

Practical considerations and tips

• Verify System 89 compatibility and confirm the enclosure dimensions to ensure a seamless installation with no rework of bus connections.
• Plan for routine maintenance checks of the MCC area to prevent loose connections, which can impact performance in high‑load, three‑phase operations.
• Maintain a spare bucket in your parts inventory to shorten downtime during critical maintenance windows.
• Leverage AmpState’s global delivery network to source and stock this bucket for multi‑site operations or international facilities.
