FAQs
Installation follows Series G MCCB guidelines: mount within a 4P protection scheme, connect metric tapped terminals with appropriate lugs, and secure the device in a standard panel framework. Use compatible accessories such as plug-in adapters or modular lugs to simplify wiring, ensure proper torque, and maintain alignment with busbar configurations for reliable protection.
With an 800A rating and 4P configuration, this MCCB delivers robust overload and short-circuit protection for motor feeders and distribution circuits. The Series G design supports reliable tripping characteristics and compatibility with motor protection strategies, enabling safer startup, better selective coordination, and reduced motor-related downtime.
Metric tapped terminals simplify wiring in European and other metric-based installations, improving lug reliability and reducing connection errors in control panels, distribution boards, and motor control centers. This feature is especially beneficial in retrofit projects and in facilities standardizing metric hardware for panel assemblies.
Public certifications are listed as 'Contact Manufacturer' in the provided data. For regulatory compliance, verify with Eaton and consult the latest datasheet or application notes to confirm CE, UL, or IP ratings for your specific configuration and market requirements.
