FAQs
Installation starts with confirming the bottom feed configuration and three-pole, three-wire wiring. Mount the device in a suitable NEMA-rated enclosure, connect the three supply lines to the bottom feed terminals, and integrate the SPVR and ground-fault wiring to the control transformer as specified. Verify proper clearance and alignment before energizing, and ensure all protective devices are rated for 208V systems.
Key ratings include 2000A amperage, 120V control voltage, and 208V system voltage with fusible protection. It features three poles and three wires with a bottom feed arrangement. Terminations are designed for robust low-voltage power distribution applications, and the device supports SPVR with capacitor trip, enhancing coordination and reliability in motor feeders.
Yes. With a 2000A rating, 208V system compatibility, and fusible protection, CB2033B120208GRA9 is well-suited for large-motor feeders in switchgear. The SPVR trip device improves protection timing, while UL Listing and NEMA enclosure compatibility support compliant, durable installations in industrial environments.
The unit is UL Listed and carries NEMA ratings including 1, 3R, 4, and 12, enabling use across a range of indoor and outdoor industrial applications. These certifications help meet regulatory and safety requirements while ensuring suitability for harsh environments and diverse installation conditions.
SPVR provides rapid, capacitor-assisted tripping that minimizes fault duration and reduces wear on contacts, lowering maintenance frequency. Ground fault detection enhances safety and reduces risk of personnel injury and unplanned downtime. Together, these features improve uptime, reduce maintenance costs, and extend the service life of power distribution assets.
