FAQs
For optimal performance, plan a bottom feed layout with three wires and ensure space for the 16 inch depth, 32 inch height, and 24 inch width footprint. Verify the 2000A amperage rating aligns with the motor feeder load and confirm the SPVR capacitor trip device is configured for the intended fault protection. Optional ground fault or auxiliary provisions should be added prior to commissioning.
The SPVR capacitor trip device provides a controlled and delayed trip signal for fault conditions in single-phase portions of the circuit, reducing nuisance trips in healthy systems. In a three-pole assembly, it helps ensure reliable coordination with downstream protective devices, improving selectivity and minimizing unplanned outages in motor feeders or critical loads.
Yes. The CB2033B120208RAR7 is designed for three-pole, bottom-fed installations with 2 NO-2 NC contacts and 3-wire configurations. Its UL Listed rating and 208V system compatibility support seamless integration with both Eaton and compatible third-party switchgear, and optional provisions allow expansion to auxiliary signaling or ground fault functions as needed.
The unit carries UL Listed safety certification and supports broad enclosure protection with NEMA ratings 1, 3R, 4, and 12. This combination covers indoor, damp, and rugged environments, helping meet regulatory and safety requirements while protecting high-current loads in demanding applications such as manufacturing and process facilities.
The high current rating and integrated fault-tripping capabilities reduce unplanned downtime and maintenance costs by improving fault diagnosis and preventing cascading failures. A one-year Eaton warranty and optional auxiliary provisions support long-term reliability, while bottom-feed design and diagnostic LEDs simplify commissioning and ongoing maintenance in busy electrical rooms.
