Compatibility & installation notes

AmpState’s 11-350 Breaker MCC Bucket is designed to slot into existing Eaton‑Westinghouse 11‑350 assemblies. When replacing a bucket, confirm the following for a smooth installation:

• Match the three‑pole design and 600 V rating to your system specifications.
• Verify vertical frame alignment with the MCC rail and bus bar interfaces.
• Coordinate with your facility’s electrical safety protocols and lockout/tagout procedures during installation.
• Consult relevant Eaton‑Westinghouse documentation for torque specs, terminal crimps, and any OEM tooling requirements.

Practical tips for best results

• Plan retrofits during scheduled maintenance windows to minimize operational impact and downtime.
• Label buckets clearly to reflect phase assignments and load distribution, aiding future maintenance and troubleshooting.
• Use compatible fusing and protective devices rated for 90 A at 600 V to maintain coordinated protection across the MCC.
• Store spare buckets in a clean, dry area to preserve contact integrity and prevent corrosion prior to installation.
