FAQs
CB1233B120480A9 is designed for bottom-feed, three-pole installations and supports standard Eaton switchgear. It integrates with three-wire, 480 V circuits up to 1200 A and is UL Listed, ensuring straightforward replacement or upgrade in compatible panels. When planning retrofits, verify enclosure clearance and wiring routes to maintain proper clearance around the three-pole contacts and fuse assemblies.
Key specs include 1200 A amperage rating, 480 V system voltage and 120 V control voltage. It is fusible protection with a bottom feed, three-pole configuration and no ground fault, compatible with NEMA 1, 3R, 4, and 12 enclosures. This combination supports robust protection for high-current industrial loads while enabling reliable control panel operation.
Yes, the unit carries UL Listed certification and a NEMA compatibility range (1, 3R, 4, 12), enabling use in a variety of indoor and harsh environments. For outdoor or wet locations, ensure enclosure selection aligns with NEMA ratings and verify that grounding provisions, ancillary protections, and proper sealing are in place to maintain safe operation.
Key considerations include using the bottom-feed configuration to minimize wiring complexity, aligning with three-wire phase connections, and leveraging optional features such as ground fault relay, blown fuse detection, and auxiliary contacts for enhanced diagnostics. Proper torque on connections and adherence to Eaton installation guidelines further reduce the risk of mis-wiring and premature failures.
Expected benefits include reduced nuisance trips due to precise fusible protection, lower maintenance calls thanks to diagnostic options, and longer panel life from reliable, heat-managed switching. The unit’s robust construction and UL Listing support industry compliance, while the bottom-feed design saves cabinet space and simplifies future upgrades, improving total cost of ownership over time.
