FAQs
The LWC4630 is a four-pole, L-frame complete molded case circuit breaker designed for line and load terminal configurations. It fits standard Series C MCCB footprints and supports wiring schemes used in industrial power distribution panels, motor control centers, and control panels, enabling straightforward retrofits and upgrades without extensive rewiring.
LWC4630 offers a 100 kAIC interrupt rating at 415 Vac. This high interrupt capability means the breaker can safely interrupt large fault currents, protecting conductors, components, and personnel. In practice, this reduces arc-flash risk and panel damage during fault conditions in demanding 690 Vac networks.
The T207 is an interchangeable thermal-magnetic trip type that provides both overload and short-circuit protection with a defined trip curve. This enhances protection coordination, reduces nuisance trips, and allows field adjustment to match motor and distribution characteristics in your application.
LWC4630 is a four-pole MCCB with line and load terminals, designed around an L-frame. It supports a 630 A rating and operates at 690 Vac or 250 Vdc. The device aligns with IEC-rated standards and is suitable for wiring schemes that require reliable high-current protection in control panels.
The complete four-pole breaker design simplifies installation in panels and cabinets, while IEC-rated certification supports global compliance. Availability of accessories and documentation, including application notes and product guides, facilitates quicker commissioning, easier service, and consistent maintenance across multiple sites.
