FAQs
The LWC3315D09 is a three-pole, L-frame molded case circuit breaker designed for metric mounting hardware with line and load end caps. It fits standard World-class panels that accept Series C MCCBs. Ensure the panel has suitable space, correct bus spacing, and compatible terminal kits. This MCCB simplifies retrofits by maintaining consistent frame size and a common mounting footprint, reducing installation time and risk.
Key ratings include 315A amperage, 690 Vac and 250 Vdc voltage ratings, and a 100 kAIC interrupt rating at 415 Vac. The unit uses an interchangeable thermal-magnetic trip type (T207) for precise protection coordination. These specs support demanding loads while meeting international safety standards and providing reliable fault-current interruption in heavy-duty applications.
Yes. With three poles, IEC-rated protection, and a robust 100 kAIC interrupt capability, the LWC3315D09 is well-suited for motor control centers and main distribution panels. Its compact L-frame, metric mounting, and line/load end caps streamline installation in MCCs and distribution cabinets, enabling safe motor startup protection and dependable power distribution across manufacturing lines.
This product is IEC Rated, providing international compliance for diverse markets. Additionally, Eaton provides UL-listed 100%-rated molded case circuit breakers documentation, confirming suitability for safety-focused applications and ease of integration into UL-listed panels. These certifications support global procurement strategies and supplier qualification processes for regulated industries.
The unit’s interchangeability within the Series C family simplifies spares and replacement strategies, reducing downtime during maintenance. A clear warranty policy (one year from installation or eighteen months from shipment) protects initial investment while enabling planned replacements. Operators benefit from predictable lifecycle planning, easier stocking of compatible parts, and reduced risk of obsolescence in evolving control architectures.
