FAQs

Choose CB1633B120480GAX7 for three-pole, bottom-fed assemblies with 2NO-2NC contacts to match existing control logic. Ensure enclosure is rated for the NEMA 1, 3R, 4, 12 environments and that the frame supports fusible protection. Optional provisions like auxiliary contacts and Kirk provisions can simplify integration with existing Eaton devices.
A 1600A rating handles high fault currents typical of large feeders and motors, reducing the need for multiple devices. Select complementary fusible protection sized for anticipated faults and confirm enclosure clearance. Coordination with downstream devices and proper grounding minimize nuisance trips while maintaining fast, reliable protection during faults.
Yes. The unit provides a 120V control voltage suitable for standard industrial control circuits. Its ground fault options and control power transformer support safer operation in facilities that require reliable control power. When integrating, verify control wiring meets 120V practices and that any optional ground fault relay is compatible with the overall control scheme.
The CB1633B120480GAX7 is UL Listed, ensuring compliance with electrical safety standards for industrial equipment. It also carries NEMA ratings of 1, 3R, 4, and 12, enabling reliable operation in enclosures exposed to dust, moisture, and varying temperatures. These certifications support audits, vendor qualification, and safe deployment in regulated industries.
The switch’s high-current capability, robust enclosure compatibility, and optional protection features reduce downtime by delivering dependable trips and fewer nuisance events. Integration with existing Eaton devices streamlines spare parts and maintenance planning, while UL/NEMA compliance lowers retrofit risk and extends service life for critical plant feeders.
