FAQs
Yes. The CB4033T120480RAXCT is designed for 480 V systems with a top-feed fuse configuration and three-pole, three-wire wiring. This arrangement simplifies wiring, supports high-current protection, and integrates smoothly with existing switchgear footprints. When selecting conductors and enclosure space, verify the top-feed lead lengths and clearance per the system’s NEMA rating.
The SPVR capacitor trip device provides a capacitor-based trip mechanism that ensures a controlled, charged trip sequence before switch closure. This improves coordination with downstream protection and reduces nuisance tripping due to transient conditions. In practice, SPVR enhances protection accuracy for single-phase faults, aiding reliable motor protection in demanding applications.
Absolutely. The CB4033T120480RAXCT carries UL Listed certification and is compatible with multiple NEMA enclosure ratings, enabling installation in demanding environments. Its three-pole, fusible design supports modular protection schemes, while the top-feed configuration simplifies field wiring. Always confirm enclosure rating and ambient conditions to ensure full compliance with local codes.
The product carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, inspect the auxiliary contacts, verify the capacitor trip device integrity, and confirm fuse status at planned intervals. Routine checks help ensure reliable protection and reduce unexpected downtime in continuous operations.
