FAQs
CB3033T120480A is designed for top-feed installation in 3-pole, 480 V systems. Ensure the panel has adequate clearance for large enclosure dimensions (22.5 in depth, 28 in height, 40 in width) and accommodates three wires. Use proper lug torque per Eaton guidelines and select the appropriate optional accessories, such as Ground Fault Relay or auxiliary contacts, to match your protection scheme.
This switch is rated for 3000 A with a 120 V control voltage and a 480 V system voltage, suitable for fusible protection. It supports NEMA 1, 3R, 4, and 12 enclosures, and is designed for top-feed configurations without ground fault protection unless the optional relay is added. The device is UL Listed for safety and reliability in industrial environments.
Yes. With a 3000 A rating and 480 V capability, this switch is well-suited for motor control centers and switchgear panels that require robust high-current protection. Its top-feed design simplifies wiring, while optional accessories provide tailored protection schemes. It is particularly effective in applications needing reliable protection with standard plant control architectures and easy retrofit options.
The CB3033T120480A carries UL Listed certification, validating safety and performance for industrial use. It is compatible with multiple NEMA enclosure ratings (1, 3R, 4, 12), which supports compliance across varied environments. While CE and SIL ratings are not listed for this specific unit, UL Listing and enclosure compatibility help meet common U.S. industrial safety requirements and facilitate audits.
Maximize ROI by leveraging the unit’s high current rating (3000 A) to delay equipment upgrades and minimize downtime from protective failures. UL Listed safety reduces compliance risk, while the option for Ground Fault Relay and auxiliary contacts enables precise protection without unnecessary trips. Regular lug torque checks, maintenance of fusible protection, and keeping spare parts readily available extend service life and improve uptime.
