Special features
Interlock, Single-phase voltage relay with capacitor trip device (SPVR)
Feature → Business Impact → Application: The 3000A amperage rating enables protection of large motors and feeders, reducing the risk of unplanned downtime and allowing for smaller, more cost-efficient protection schemes in heavy‑duty panels. Application: mine/steel, pumps, and large conveyors where peak currents test protection limits.Feature → Business Impact → Application: 2NO‑2NC contact configuration provides flexible wiring and fault isolation, speeding assembly and maintenance while simplifying control logic in standard control panels. Application: motor starters, interlocked feeders, and safety‑critical circuits.Feature → Business Impact → Application: Bottom feed and bottom fuse configuration streamline cabinet layout and improve fault clearance times, supporting compact installations and safer wiring routes. Application: switchgear, switchboards, and control enclosures with limited rear clearance.Feature → Business Impact → Application: Ground fault with control power transformer and optional interlock/SPVR enhance safety and trip accuracy, reducing nuisance trips and enabling capacitor‑based trip signaling for rapid fault response. Application: earth‑fault sensitive environments and single‑phase protection scenarios.Feature → Business Impact → Application: NEMA 1, 3R, 4, 12 compatibility broadens enclosure options and mitigates regulatory constraints, making it easier to meet site‑specific protection standards. Application: harsh environments, weatherproof cabinets, and indoor/outdoor installations.Feature → Business Impact → Application: UL Listed certification and fusible protection deliver regulatory compliance and reliable overcurrent protection, supporting long‑term maintenance contracts and OEM integrations. Application: industrial automation assemblies, process equipment, and energy‑intensive facilities.
