Special features
Single-voltage relay with capacitor trip device (SPVR), BFD with no lights (trips switch)
Feature → SPVR capacitor trip device is designed to shut the circuit cleanly when fault conditions are detected, reducing arc energy and enabling quicker, safer re-energization. Business impact → minimizes downtime and extends equipment life by preventing recurrent fault events. Application → motor feeders and large power distribution points in manufacturing cells benefit from reliable, rapid trips. Feature → Three-pole, top-feed fusible design simplifies wiring and improves fault isolation, which reduces miswiring risk and speeds panel assembly. Business impact → faster commissioning and lower maintenance overhead with a robust, code-compliant installation. Application → switchgear, service entrances, and distribution panels in harsh environments. Feature → 4000 A amperage rating with 480 V system voltage and 120 V control voltage ensures compatibility with high-current plant infrastructure while enabling straightforward control circuit interfacing. Business impact → supports large motor starts and high-inrush loads without compromising protection. Application → centralized power distribution hubs and heavy machinery in process industries. Feature → NEMA compatibility (1, 3R, 4, 12) enhances enclosure versatility and weather resistance. Business impact → reduces equipment protection gaps and supports outdoor or damp installations. Application → outdoor switchgear rooms, wash-down areas, and rugged production floors. Feature → Optional ground fault relay and auxiliary provisions extend protection and monitoring. Business impact → strengthens safety compliance and enables proactive fault detection. Application → facilities seeking enhanced safety analytics and remote diagnostics. Feature → UL Listed certification validates safety compliance for regulated environments. Business impact → simplifies procurement and qualification for certifications and audits. Application → industrial plants with strict vendor qualification requirements.
