Eaton CB2533T120480GAX6 Pringle bolted switch - UL Listed
Part Number: CB2533T120480GAX6
Quick Summary
Eaton pringle bolted pressure contact switch is a high-capacity protective device for heavy-duty industrial power feeds and motor circuits. Maintenance teams often contend with nuisance trips, slow fault isolation, and downtime when protection isn’t fast or reliable enough. UL Listed certification accompanies robust ratings and enclosure compatibility, including NEMA 1, 3R, 4, and 12, so it performs in diverse environments. With a 2500 A amperage rating, 480 V system voltage, and top-feed configuration, it scales to growing plants, while 120 V control voltage supports straightforward control wiring in new and retrofit projects. For business value, expect improved uptime, simplified installation, and easier maintenance within modern switchgear.

FAQs
When planning installation, verify that the panel supports a three-pole, top-feed fusible configuration and that the control circuit is wired at 120 V. Ensure enclosure selection aligns with the listed NEMA ratings (1, 3R, 4, 12) and that proper clearances around the top-feed connections are observed. The UL Listed certification confirms compliance with relevant safety standards. Prepare for ground fault protection options as needed.
The charge-before-close mechanism ensures that the switch energizes only after a reliable fault check and charge sequence. This reduces arcing during make/break transitions and minimizes contact wear, enhancing safety and lifecycle. For operators, it translates to more predictable operation, fewer nuisance trips, and lower maintenance intervals in high-current feeder applications.
Yes. The CB2533T120480GAX6 is designed for 480V systems with a 2500A current rating, three-pole topology, and fusible protection. It is well-suited for main disconnects, motor feeders, and large loads within switchgear. Ensure compatibility with your motor protection scheme and verify that the available enclosure type and installation space meet NEMA requirements.
This model is UL Listed, supporting compliance with standard electrical safety requirements. It also provides NEMA compatibility ratings including 1, 3R, 4, and 12, which broadens installation options from indoor control rooms to certain outdoor or harsh environments. These certifications underpin reliable protection in industrial power distribution and automation equipment.
Expect improved uptime due to robust protection, reduced nuisance trips, and safer maintenance thanks to the charge-before-close mechanism. The high current rating simplifies protection coordination, often reducing the number of devices in a downstream protection scheme. Over time, this can lower total cost of ownership through fewer replacements, easier retrofits, and streamlined commissioning in new or upgraded switchgear.
