FAQs

The LW3630F frame is designed for frame-only installation within standard electrical panels and is compatible with Eaton Series C components. For ease of installation, use Eaton plug-in adapters and modular accessories specified for the Series C MCCB family. Ensure three-pole mounting and alignment with bus bars, then connect to the designated terminals and verify clearances per panel design. This approach minimizes wiring errors and enables quicker commissioning in motor control centers and control panels.
LW3630F is rated for 630 A, 690 Vac and 250 Vdc, with a trip type of T207 and three poles. It offers an interrupt rating of 45 kAIC at 415 Vac, providing a strong short-circuit withstand capability. These specifications support reliable protection for large motors and heavy loads in industrial automation environments while maintaining compatibility with IEC standards.
Yes. The LW3630F frame is well-suited for motor control centers and machine rooms requiring robust, compact protection. Its frame-only design, three-pole configuration, and high interrupt rating enable scalable protection schemes. The IEC Rated certification supports global deployment, making it a practical choice for multi-site manufacturing and automation projects.
The LW3630F carries IEC Rated certification, indicating compliance with international safety and performance standards. This certification supports worldwide deployment in regulated environments and helps streamline procurement and approval processes for projects that require IEC-aligned MCCBs. Always verify local requirements, but IEC Rated framing generally aligns with global electrical codes and safety practices.
The LW3630F benefits from Eaton’s standard warranty policy, including a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Maintenance considerations focus on periodic inspection of the trip mechanism, clean contacts, and verifying connector integrity. Using a frame-only solution can reduce spare-part diversity and simplify replacement strategies, delivering lower lifecycle costs in automation systems.
