FAQs
For installation, plan bottom-feed wiring and ensure the panel enclosure accommodates a three-pole, fusible switch with SPVR. Verify a 208 V system, 120 V control circuit, and UL Listed equipment compatibility. Allow space for the device footprint (22.5 in depth, 32 in height, 40 in width) and observe clearances per enclosure guidelines. Wiring should reflect the three-wire, three-pole configuration with proper grounding practices where applicable.
The SPVR capacitor trip device provides a charge-before-close mechanism that coordinates with the control transformer to ensure a reliable, fast trip on fault events. This reduces nuisance trips from transient events and enhances selectivity in single-phase protection schemes, improving system reliability in high-current feeders and minimizing downtime in critical processes.
Yes. With a 3000 A amperage rating, 208 V system voltage, and three-pole configuration, this switch is well-suited for main feeders in switchgear and motor control centers. Its bottom-feed design and fusible protection streamline integration into MCCs and panel boards, while UL Listing supports compliance and procurement across industrial automation environments.
The CB3033B120208RCT is UL Listed and supports multiple enclosure ratings, including NEMA 1, NEMA 3R, NEMA 4, and NEMA 12. These certifications and ratings ensure safe operation in a range of indoor and outdoor industrial environments, aiding regulatory compliance and reducing the need for additional protective enclosures in many installations.
Maintenance primarily involves periodic inspection of the fusible elements, SPVR operation, and auxiliary provisions to verify integrity. ROI benefits arise from reduced downtime due to faster fault isolation, fewer nuisance trips, and streamlined protection in a single, integrated package, which lowers panel complexity and total installed cost over the equipment’s lifecycle.
