FAQs
CB1233B120480GRAX uses a bottom feed, three-pole design with three wires, designed for compact panels. When planning installation, verify enclosure type against NEMA ratings to match indoor or outdoor use, ensure adequate space for 16 in depth, 24 in width, and 32 in height, and account for optional Ground Fault Relay wiring if needed.
The device provides a 1200 A amperage rating with a 480 V system voltage and 120 V control voltage. It offers fusible protection, a single-phase voltage relay with capacitor trip device (SPVR), three-pole, three-wire configuration, and UL Listed safety certification to meet industrial protection requirements.
Yes. The unit is rated for multiple enclosures per NEMA: 1, 3R, 4, and 12, enabling indoor and outdoor installations in challenging environments. UL Listing further supports compliance, while the fusible protection and robust 1200 A rating provide reliable operation under demanding conditions.
Optional features include Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, and Kirk Provisions. These options allow tailored protection schemes, enhanced monitoring, and expanded control capability, facilitating easier integration with existing control architectures and compliance with site-specific safety requirements.
The SPVR provides selective, capacitor-assisted trip logic for single-phase faults, enabling quicker clearance of faults and reducing the likelihood of non-essential trips. This improves overall system reliability for motor feeders and minimizes unplanned downtime in manufacturing lines and critical process equipment.
