FAQs
CB2033T120480GRAO is designed for three-pole, three-wire configurations with top-feed. It supports 480 V system voltage and fusible protection, making it suitable for standard Eaton switchgear assemblies. When installing, verify enclosure clearances and ensure proper control power transformer connections for reliable ground fault sensing and SPVR operation.
SPVR stands for single-phase voltage relay with capacitor trip device. It coordinates protection by using a capacitor-based trip circuit to initiate a controlled, fast trip on detected faults. In practice, this reduces nuisance trips while ensuring rapid disconnection of faulty circuits, improving overall system safety in motor control and feeder protection.
Yes, the CB2033T120480GRAO is UL Listed, confirming safety compliance for industrial use. It also offers NEMA compatibility (NEMA 1, 3R, 4, 12) for indoor and outdoor or rugged environments, meaning it can withstand dust, rain exposure, and typical factory conditions when properly enclosed.
The base model includes ground fault protection with a control transformer and optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection. This combination helps detect faults quickly, minimize damage, and support proactive maintenance by signaling abnormal conditions before they escalate, ultimately reducing repair costs.
Upgrading to CB2033T120480GRAO can lower downtime through precise trip coordination (SPVR) and reduce nuisance trips with single-phase protection features. The UL Listed safety compliance and rugged NEMA-rated enclosure extend service life in challenging environments, while optional fault-detection features enable predictive maintenance, improving overall plant reliability and reducing unplanned outages.
