FAQs
The CB2533T120480RAX uses a top-feed, three-pole configuration and fusible protection, making it straightforward to retrofit into standard top-fed switchgear. It supports optional Kirk provisions and auxiliary contacts, enabling seamless integration with existing control panels and protection schemes while preserving wiring simplicity and clear fault diagnostics.
Verify a 2500 A amperage rating, 480 V system voltage, and 120 V control voltage. The unit is three-pole with three wires, fusible protection, and is UL Listed. Check NEMA ratings (1, 3R, 4, 12) to ensure enclosure compatibility and confirm availability of optional features like ground-fault relays and auxiliary contacts for your application.
Yes. With a 2500 A rating and 480 V system capability, this switch is designed for heavy motor feeders and switchgear in industrial plants. Its capacitor-trip device (SPVR) improves reliability, while three-pole protection and top-feed configuration support robust motor control centers and power distribution installations.
The CB2533T120480RAX is UL Listed and rated for multiple NEMA environments (1, 3R, 4, 12). These certifications facilitate compliance in harsh or outdoor environments and speed regulatory approvals during panel upgrades or new installations.
Expect reduced downtime due to faster, more reliable trips from SPVR protection and fewer nuisance trips. The optional ground-fault, blown fuse detection, and auxiliary provisions enhance diagnostics, enabling proactive maintenance. Consolidating protection in a single device lowers spare parts costs and simplifies training and commissioning, boosting overall return on investment.
