FAQs
This unit excels in switchgear, motor control centers, and distribution panels requiring high-current protection with a three-pole configuration. Its top-feed design and fusible protection simplify wiring routes and fault containment in compact layouts, making it ideal for industrial facilities with limited space and demanding reliability needs.
SPVR stands for single-phase voltage relay with a capacitor trip device. It provides rapid, coordinated protection for single-phase circuits within a three-pole switch, improving trip accuracy and reducing nuisance outages. This is particularly valuable in motor control and power distribution applications where precise timing and reliability are critical.
The device is designed to meet NEMA ratings 1, 3R, 4, and 12, enabling use in a wide range of indoor and outdoor environments, including damp or corrosive settings and open panel installations. This broad enclosure compatibility helps streamline procurement and reduces site adaptation work.
Plan for an amperage rating of 1600A with a system voltage of 208V and a control voltage of 120V. The contact configuration is 1NO-1NC, and the unit supports top feed with fusible protection. These specs align with typical industrial distribution and motor control circuits, supporting robust protection without requiring major rewiring.
Yes. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, Kirk Provisions, and other enhancements are available. These options enable deeper protection coverage, better fault visibility, and easier integration with existing control schemes and diagnostics.
