Eaton LW4630 Molded Case Circuit Breaker - IEC Rated

The LW4630 uses a complete molded case breaker with an L-frame and four poles, offering precise protection for 630 A circuits. Business impact: improved short-circuit control reduces equipment damage and downtime, enabling safer and faster commissioning of large motor loads in distribution panels. Application: suitable for machine rooms and control panels where space and protection coordination are critical. The interchangeable thermal-magnetic trip (T207) delivers selective coordination and fast fault clearing, which translates to lower arc-flash risk and streamlined maintenance workflows. Application note: motor-driven equipment in heavy-duty lines benefits from reliable protection without complicated retrofits. The device carries a 690 Vac / 250 Vdc rating and a 45 kAIC interrupt capacity at 415 Vac, enabling robust protection in high fault-current scenarios; ideal for global panel builds. The line-and-load terminals and complete breaker design simplify installation and testing, reducing commissioning time for new panels. Industry insight: for IEC and UL environments, Series C MCCBs like the LW4630 are favored for their plug-in adapters and motor protection options, which reduce engineering time and Material Compliance risk. Compatibility with plug-in adapters and motor operators supports modular upgrades as system requirements evolve.
