FAQs
The LWC3630D09 uses the Series C F‑Frame form factor with an L‑Frame design and line/load end caps, plus metric mounting hardware. This provides straightforward compatibility with existing installations and retrofit projects, enabling quick swaps without extensive cabinet redesigns or new enclosure requirements.
Key specs include a 630 A amperage rating, 690 Vac and 250 Vdc voltage ratings, three poles, 100 kAIC interrupt rating, and the T207 trip type. These parameters define its suitability for high‑fault‑current environments and precise protection of complex, multi‑load panels.
Yes. Its IEC Rated construction, three‑pole LWC frame, and 100 kAIC interrupt capacity support robust protection for motor control centers and heavy machinery. The device’s compact dimensions and metric mounting ease integration into compact MCCs while meeting global safety requirements.
Benefit from faster installation due to metric mounting hardware, standardized end caps, and a familiar Series C form factor. The 25 lb weight and balanced dimensions simplify handling, while the 1‑year warranty (18 months from shipment) provides predictable coverage during early operation and reduces maintenance risk.
With IEC Rated certification and a high 100 kAIC interrupt rating, the LWC3630D09 aligns with global protection standards for critical loads. Its conformity with Series C specifications and interchangeable trip mechanism also supports consistent protection strategies across multiple facilities.
