Eaton Specification Sheet - CB3033B120480
Feature → Business Impact → Application: The CB3033B120480 offers three‑pole, bottom‑feed operation with fusible protection, enabling safe, predictable interruption of high‑current circuits in 480V systems. This directly improves protection coordination and reduces arc flash exposure during maintenance, translating to lower risk and uptime gains on heavy‑duty feeders in switchgear and motor control centers. Application-wise, it suits large industrial environments requiring dependable disconnection and clear fault tracing, especially where bottom‑feed layouts simplify wiring runs and cabinet design. Feature → Business Impact → Application: Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions provide enhanced safety monitoring and fault visibility, supporting proactive maintenance programs and regulatory compliance in facilities with stricter safety regimes. This reduces unplanned outages and supports remote diagnostics when integrated with Kirk provisions and auxiliary circuits. Feature → Business Impact → Application: The device’s NEMA 1, 3R, 4, 12 ratings and 120V control voltage yield broad compatibility with common industrial enclosures and control circuits, enabling faster installation and easier part‑replacement planning. It also aligns with UL Listed standards to ease supply chain approvals and asset management. Feature → Business Impact → Application: With a 3000A amperage rating and 480V system voltage, this switch handles demanding industrial loads while maintaining safe, clean disconnection events, supporting energy‑intensive processes such as stamping, extrusion, and heavy machining. Feature → Business Impact → Application: The robust 430 lb, large‑format footprint denotes a durable, serviceable device that can withstand industrial environments; the bottom feed and three‑wire configuration simplify field wiring and commissioning, reducing installation time and commissioning risk. This combination supports long‑term maintenance strategies and predictable capital expenditure in plant electrical rooms.
