Siemens Furnas 89 - Breaker MCC Bucket - 40 A, 480 V, 6" Height, 3 P | AmpState

Engineered for demanding industrial motor control environments, the Siemens System 89 Breaker MCC Bucket (40 A, 480 V, 3-Pole) from AmpState is a purpose-built replacement that preserves protection, control logic, and enclosure fit. Designed to slot directly into Siemens System 89 MCC systems, this bucket is an ideal OEM-compatible solution for retrofit projects and scheduled maintenance, minimizing downtime while maintaining original performance characteristics.

• Configuration: Breaker MCC Bucket designed for Siemens System 89 MCC architecture
• Current rating: 40 A
• Voltage: 480 V
• Poles: 3-Pole
• Height: 6 inches

Key advantages go beyond the stamp on the label. This MCC bucket preserves the exact form factor, backplane alignment, and bus-bar interface of the original System 89 components, ensuring a seamless, plug-and-play replacement that reduces commissioning time and wiring errors. With a 40 A, 480 V, 3-Pole configuration, it reliably protects and controls motor loads ranging from conveyors and pumps to fans and machine tools, keeping critical processes online with minimal disruption.

Use cases and who benefits most:

• Maintenance technicians performing OEM-equivalent replacements in existing Siemens System 89 MCC installations
• OEM integrators updating legacy systems to maintain consistency with Siemens System 89 ecosystems
• Facilities engineers planning proactive spares for critical motor-driven equipment such as conveyors, HVAC drives, pumps, and presses

Why this matters in practice:

• Direct replacement, fewer surprises—plug-and-play compatibility with your current System 89 MCC framework reduces retrofit risk and commissioning time.
• Consistent protection—preserves tripping characteristics and protection schemes for motors up to 40 A at 480 V, helping prevent mismatches that could cause nuisance trips.
• Footprint certainty—6" bucket height maintains enclosure and backplane alignment, minimizing the need for ancillary modifications.
• Global sourcing—AmpState delivers this MCC component with reliable worldwide availability, so multi-site maintenance becomes simpler and faster.

Practical tips for installation and ongoing reliability:

• Before installation, verify that the enclosure and backplane are compatible with Siemens System 89 MCC buckets to ensure correct mechanical and electrical fitment.
• Power down the system and follow lockout/tagout procedures prior to handling MCC components.
• Tighten all terminations to the manufacturer’s torque specifications and confirm wiring matches the 3-Pole configuration for balanced operation.
• Consider keeping a spare bucket on hand for critical lines to minimize downtime during planned maintenance or unexpected faults.

AmpState stands behind this component as a reliable source for MCC parts, offering global delivery and consistent, application-aware support. If your motor control center relies on Siemens System 89 components, this 40 A, 480 V, 3-Pole Breaker MCC Bucket provides a precise, durable, and compatible solution that helps maintain efficiency, safety, and uptime across your operations.
