Selling Policy 25-000 - Distribution and Control Products and Services
Split-core construction lets technicians clamp the sensor around an existing conductor without disconnecting power, cutting commissioning time and minimizing shutdown windows. This design reduces field wiring errors and improves installation safety. In practice, it speeds meter retrofits in switchgear and distribution panels, letting energy teams capture real-time current data with minimal system interruption. Primary rating of 1000A paired with a 5A secondary output delivers a robust measurement signal for metering and protection relays. The 0.50% accuracy specification reduces drift over time, supporting accurate billing and energy analytics across quarterly audits. In industrial facilities with high load variability, this precision translates to meaningful cost visibility and better demand management. Burden specification of 4.50 VA ±0.5% ensures the CT does not overly load downstream meters and controllers. This makes it compatible with common metering inputs and minimizes readout errors. For engineers, the predictable burden improves calibration confidence during commissioning and ongoing maintenance in power management systems. Operating range of -10°C to 60°C and RoHS / ANSI/IEEE C12.20 compliance provide reliability in harsh environments. The compact footprint (4.37 in x 1.24 in x 5.83 in) and 1.7 lb weight simplify enclosure planning and mounting in tight spaces. This is particularly valuable for retrofit projects where space is at a premium and regulatory adherence matters. Warranty and support from Eaton add long-term value. A one-year limited warranty from installation (or 18 months from shipment) reduces risk, while the included documentation and datasheets streamline troubleshooting and spare-parts planning.
