Eaton 211801 AZ-3-C80 MCB 3P 80 A C Curve 6kA DIN Rail

The Eaton AZ-3-C80 is a three-pole miniature circuit breaker (MCB) from the Moeller series xEffect range, engineered for overcurrent protection in industrial and advanced commercial installations. Rated at 80 A with tripping characteristic C, it operates across 230 V AC / 400 V AC three-phase systems and mounts on standard top-hat rail per IEC/EN 60715. Conductor cross-sections from 2.5 to 50 mm² are supported, making it suitable for a wide range of cable configurations.

Features and benefits:

• Current limiting class 3 limits let-through energy, reducing stress on downstream components during short-circuit events
• Wide operating temperature range of -25 °C to 55 °C suits demanding industrial environments
• Lift terminals on both top and bottom allow flexible incoming supply direction as required
• IP40 protection achievable when fitted, safeguarding against solid particle ingress in panel assemblies
• Compatible with additional AZ accessories, allowing modular expansion of the installation
• Note: a 1 °C rise above rated ambient causes a 0.5% linear reduction in current-carrying capacity - factor into thermal design

Applications:

• Overcurrent protection in three-phase industrial control panels and switchgear assemblies
• Distribution boards in advanced commercial buildings and infrastructure
• Railway and rolling stock electrical systems (certified to EN45545-2 and IEC 61373)
• Motor branch-circuit protection where characteristic C let-through is appropriate
• Panel builder installations requiring IEC/EN 60947-2 compliant protective devices

Compliant with IEC/EN 60947-2, EN45545-2, and IEC 61373. Part of the Eaton Moeller series xEffect switchgear family for industrial and advanced commercial applications.
