FAQs
For installation, plan top-feed wiring and confirm compatible NEMA enclosure placement (1, 3R, 4, 12). The three-pole, three-wire configuration requires proper phase alignment and intact grounding practices; use the optional auxiliary contacts or Kirk provisions only if your control scheme demands it. Ensure control voltage of 120 V and system voltage of 480 V are within rating, and allocate space for 16 in length, 28 in height, and 24 in width clearances where feasible.
This device supports up to 1200 A amperage, control voltage 120 V, and system voltage 480 V. It is fusible and provides 1 NO-1 NC contact configuration across three poles with a top-feed configuration. The assembly is UL Listed and designed to meet NEMA 1, 3R, 4, and 12 enclosure requirements, ensuring robust protection in varied industrial environments.
Yes. With a three-pole, three-wire configuration and a 480 V system rating, the CB1233T120480AXCT5 is well-suited for three-phase protection in industrial plants. Its 1200 A rating supports high-load lines, and its fusible protection provides appropriate fault isolation in distribution schemes, improving system reliability and uptime.
The CB1233T120480AXCT5 is UL Listed and designed to operate within NEMA-rated enclosures including 1, 3R, 4, and 12. Optional features such as ground fault relay and blown fuse detection support enhanced safety compliance. These certifications facilitate regulatory audits and ensure compatibility with common industrial safety standards.
The ROI stems from improved uptime, reduced fault downtime, and extended equipment life due to reliable tripping and isolation. Its high-current capacity, simple top-feed installation, and optional protection add-ons minimize maintenance costs and emergency service time, while UL listing and NEMA compatibility reduce commissioning risk in harsh environments.
