FAQs

The CB1233T120480GAO7 is designed for 480V three-phase power with a three-pole, three-wire configuration. It delivers reliable high-current protection (1200A) while maintaining safe operation in industrial power-distribution and motor-control panels. For retrofits, verify enclosure space and top-feed wiring to ensure straightforward integration.
This device uses a 2 normally open and 2 normally closed (2NO-2NC) contact configuration, offering flexible control logic for start/stop circuits, interlocks, and signaling. It supports complex sequencing in motor control centers and can accommodate auxiliary contacts to expand monitoring and protection schemes.
Yes. Catalog notes indicate optional Ground Fault Relay and related provisions are AVAILABLE. This enables ground-fault protection in control power transformers and associated circuits, helping to guard personnel and equipment while improving fault isolation and diagnostic capability.
The switch is UL Listed and supports NEMA ratings for enclosure protection: NEMA 1, 3R, 4, and 12. This combination makes it suitable for industrial, wash-down, and outdoor installations, delivering dependable performance despite dust, moisture, or temperature variations.
The product follows Eaton’s standard warranty policy (Warranty: 25-000; one year from installation or eighteen months from shipment, whichever occurs first). For ongoing maintenance, optional features like blown-fuse detection and auxiliary contacts help simplify fault diagnostics and extend asset lifecycle via proactive monitoring.
