FAQs
The LGS4630AAG is designed for metric mounting and line/load terminal connections, enabling quick, secure integration into IEC-style panels. Its four-pole LG frame fits standard MCCB slots and supports space-efficient layouts. When wiring, ensure proper torque on mounting hardware and verify compatibility with the panel’s bus bar configuration to maintain reliable protection and easy maintenance.
Key specs include a 630 A amperage rating, 600 Vac nominal voltage, and an adjustable thermal/magnetic trip. It provides interrupt ratings of 25 kAIC at 600 Vac, 50 kAIC at 415/480 Vac, and 85 kAIC at 240 Vac. The device is a four-pole LG frame complete breaker with line/load terminals and metric mounting hardware.
Yes. Its high interrupt ratings across voltages support protection in facilities with significant fault currents. The adjustable thermal and magnetic trip units enable precise coordination to protect critical loads while allowing upstream devices to remain energized, reducing unnecessary downtime. For best results, coordinate settings using system fault studies and panel-specific trip curves.
The LGS4630AAG is UL Listed and HACR rated, aligning with electrical safety standards for general-purpose motor and HVAC protection. While adjustable trip units can be used in IEC markets, the complete LG-series MCCB supports certified protection in both industrial automation and building systems, provided proper certification alignment with local regulations is observed.
Eaton provides a standard warranty policy of one year from installation or 18 months from shipment, whichever occurs first. Routine maintenance includes periodic inspection of terminals, trip settings verification, and replacement of worn components per Eaton guidance. With a 20 lb unit and metric mounting, servicing in field cabinets remains straightforward, supporting steady uptime and predictable TCO.
