FAQs
Install the CB1233T120480GRA97 with top-feed wiring to match its three-pole configuration. Ensure proper clearance for a 16 inch by 24 inch by 28 inch footprint and the 180 lb weight, and follow torque specs for all connections. Consider optional ground fault relay or auxiliary contact provisions to suit control schemes and safety interlocks in MCCs and feeders.
The SPVR capacitor trip device provides a faster, controlled trip sequence with a charge-before-close mechanism, reducing nuisance trips while ensuring reliable fault clearance. This is particularly beneficial for sensitive feeders and motor control applications, where precise protection timing improves safety and minimizes unplanned outages.
Yes. The switch is rated for 480V systems with a 1200A amperage rating and a three-pole, 3-wire configuration, making it appropriate for high-current feeders and motor control centers. Its design supports top-feed installation and NEMA-rated enclosures, helping integrate with standard MCC layouts and reducing integration risk.
This unit is UL Listed, providing essential electrical safety certification for industrial installations. It is designed to fit NEMA-rated enclosures (NEMA 1, 3R, 4, 12), supporting rugged environments. While CE or SIL ratings are not listed for this model, UL Listing and enclosure compatibility align with common corporate and regulatory safety requirements.
The CB1233T120480GRA97 offers durable, high-current protection with a long service life, reducing downtime and field service calls. Features like SPVR trip, ground fault options, and a robust top-feed design lower maintenance costs and simplify future upgrades. The reliability of UL Listed protection translates into faster issue resolution and improved plant uptime.
