Direct OEM replacement for retrofit and modernization—this MCC bucket is engineered to drop into existing Siemens TIASTAR 95+ systems without intrusive rework. Its mechanical fit, electrical characteristics, and trip behavior align with the original equipment, helping you preserve protective coordination and minimize downtime during swap-outs.

Why this matters in real-world use — in industrial settings with conveyors, pumps, fans, and other heavy motor loads, a reliable 40 A, 600 V breaker bucket protects against short circuits and overloads while maintaining smooth operation of the motor control center. The 3-pole configuration ensures synchronized protection across all phases, reducing the risk of unbalanced faults and extension of fault clearance times.

Ideal use cases include:

• Upgrading aging MCCs to maintain current protection ratings without reengineering the panel
• Supporting retrofits in manufacturing lines that rely on Siemens TIASTAR 95+ architecture
• Replacing failed or worn MCC buckets to restore reliable motor protection with minimal field adjustments

Performance and compatibility — built to integrate with the Siemens TIASTAR 95+ motor-control ecosystem, this breaker bucket preserves alignment with wiring schemes, bus bars, and control logic. It’s suitable for environments where robust protection, predictable trip curves, and long service life are essential. AmpState backs the part with global delivery, ensuring rapid shipping and support no matter where your facility is located.

Practical notes for installation and operation — verify mounting compatibility with your current MCC frame, confirm the 3-pole configuration matches your protection scheme, and assess any site-specific derating requirements dictated by temperature or enclosure conditions. For best results, pair this bucket with the corresponding Siemens TIASTAR 95+ components to maintain coordinated protection and system reliability.
