FAQs
This model is designed for top-feed, three-pole, three-wire installations with 480 V system voltage and 120 V control voltage. It supports UL Listed use and NEMA ratings of 1, 3R, 4, and 12, making it suitable for motor control centers and large industrial panels. Optional ground fault relay and auxiliary contacts expand compatibility for safety-conscious layouts.
The capacitor trip device provides a controlled, charge-before-close sequence that reduces inrush and arcing, while the interlock prevents premature or unintended operation. Together, they enhance personnel safety and protect downstream equipment in high-current switching scenarios common to process automation and heavy manufacturing.
Key specs include 2000A amperage rating, 120 V control voltage, 480 V system voltage, and 1NO-1NC contact configuration. The unit is fusible with top feed and three-pole operation, and it supports 3-wire wiring with no ground fault by default. It is UL Listed and compatible with NEMA 1, 3R, 4, 12 enclosures.
Yes. The catalog notes indicate optional Ground Fault Relay and other protective provisions are available. This enables enhanced protection in systems where ground-fault sensing is required, helping to meet stricter safety standards and down-stream protection coordination.
Plan for top-feed mounting to align with enclosure layouts, and ensure enclosure ratings match the NEMA compatibility (1, 3R, 4, 12). The unit’s 180 lb weight and dimensions (16 in L, 24 in W, 28 in H) may require suitable handling equipment. UL Listing supports compliance with industrial safety and maintenance programs.
