Special features
Single-phase voltage relay with capacitor trip device (SPVR), BFD with three normally on lights (trips switch)
Feature: High amperage rating enables direct protection of large motor feeders. Business Impact: With a 4000A rating, it minimizes nuisance trips and reduces fuse replacements, improving line uptime. Application: Ideal for three-pole, 208V systems in manufacturing lines and distributed motor control scenarios. Feature: Capacitor trip device (SPVR) provides coordinated fault clearance. Business Impact: Speeds fault detection and improves coordination with upstream protection, reducing motor damage risk and service interruptions. Application: Suited for single-phase protection schemes in compact switchgear with capacitor-based timing. Feature: 2NO-2NC contact configuration offers flexible control logic. Business Impact: Enables signaling, interlocks, and control loops in a single unit, cutting wiring complexity and installation time. Application: Beneficial in control panels where both status indication and interlock control are required. Feature: Top feed and fuse configuration simplify installation. Business Impact: Clear feed path and easier field wiring reduce commissioning time and wiring errors. Application: Especially advantageous for top-entry enclosures and retrofit projects in retrofits. Feature: No ground fault option supports versatile protection planning. Business Impact: Optional ground fault relay readiness helps meet specific safety standards and reduces nuisance trips in sensitive facilities. Application: Use where ground fault monitoring is part of the protection scheme. Feature: NEMA-rated enclosure compatibility and UL Listed timing. Business Impact: Ensures compliance with common industrial enclosure standards, lowering risk of non-compliance and failure in harsh environments. Application: Suitable for use in NEMA 1, 3R, 4, 12 environments across power distribution cabinets.
