FAQs
Plan for a bottom-feed, three-pole configuration within a UL Listed, NEMA-rated enclosure (1, 3R, 4, 12). Ensure the 1200 A/480 V main feeders are sized for the load, and accommodate the 16 in length, 24 in width, and 32 in height footprint with a 200 lb weight. Provide space for wiring access to the optional ground fault relay and auxiliary contacts if required.
It includes a capacitor trip device (SPVR) and a bottom-feed fusible configuration that delivers rapid, reliable trips with minimal nuisance operations. This arrangement optimizes protection for single-phase feeders within switchgear, reducing downtime and improving coordination with downstream relays in industrial power systems.
Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, Kirk Provisions, and Auxiliary Contact Provisions are available. These options simplify integration into protection schemes, improve fault signaling, and reduce external wiring in control panels and MCCs.
The unit is UL Listed and carries NEMA ratings of 1, 3R, 4, and 12, supporting installation in a range of environments from standard plant rooms to harsher industrial settings. System voltage is 480 V with a 120 V control circuit, conforming to common electrical standards in industrial facilities.
Eaton provides a warranty of one year from installation or eighteen months from shipment, whichever comes first, offering protection against manufacturing defects. Combined with robust construction and widely available replacement parts, this supports lower lifecycle cost and higher uptime for critical power protection deployments.
