Split-core design allows installation around live conductors without disconnecting the circuit, delivering non-invasive sensing that minimizes downtime. This is especially valuable during plant turnarounds, panel upgrades, or EMS integrations where time is money. By removing the need to open enclosures, technicians can retrofit meters and monitors into existing distribution boards and control panels with confidence. The 2.60 x 6.25 inch window accommodates typical busbar layouts, enhancing placement flexibility in cabinets. With a 500A primary rating and a 5A secondary output, the M080-501 directly interfaces with standard metering and protection equipment, reducing secondary wiring complexity and signal conversion losses. This aligns with modern energy management systems and submetering schemes, enabling tighter current measurement budgets and simpler calibration workflows. The device supports seamless integration in new builds and retrofits of power distribution panels. 1% accuracy guarantees tight measurement tolerances across the operating range, improving billing accuracy and demand calculation for peak shaving programs. In data centers and manufacturing floors, precise CT readings translate into actionable insights for energy optimization and compliance reporting. This performance is resilient to common electrical noise thanks to Eaton’s design and testing protocols. Window size of 2.60 x 6.25 inches delivers flexible routing in crowded panels, allowing installers to position the CT around multiple conductors without crowding existing hardware. The compact footprint paired with a 6.25 inch length simplifies mounting behind covers and in tight enclosures, accelerating field installs and reducing rework during commissioning. UL Recognized and CSA Certified performance underlines safety and regulatory compliance in industrial environments, minimizing procurement risk and accelerating approvals for panel builds. The 1-year warranty adds a practical assurance for maintenance windows and service contracts, supporting long-term reliability in critical power paths. Weight of 7.5 lb and a robust construction support installation in challenging industrial spaces, while the 7.5-pound mass helps with handling during wiring and mounting. This device is designed for durable operation in temperatures within typical low-voltage power systems, contributing to lower maintenance demands.

FAQs
The M080-501 uses a split-core design, allowing installation around live conductors without shutting down equipment. This enables rapid retrofits in control panels and distribution boards, reducing downtime. Its 2.60 x 6.25 in window and 7.5 lb weight help technicians maneuver the device through crowded enclosures, improving first-time install success and reducing rework.
With a 500A primary rating and a 5A secondary output, the sensor directly interfaces with common metering systems, minimizing secondary wiring and signal conversions. Its 1% accuracy supports precise energy accounting, while UL Recognized and CSA Certified status ensures regulatory compliance. The compact window facilitates installation in EMS and submetering setups in new builds or retrofits.
Yes. The M080-501 is UL Recognized and CSA Certified, meeting essential safety and regulatory requirements for industrial power paths. This reduces procurement risk and streamlines approvals for panel builds and energy management deployments. The combination of certification plus robust performance supports safe operation in demanding environments.
To maximize accuracy, install the CT around a single conductor carrying the load and avoid routing through multiple conductors. Keep signaling wires separated from high-current paths to minimize electromagnetic interference. Use proper torque on mounting hardware and ensure the window remains unobstructed to preserve the specified 1% accuracy across the rated current range.
The split-core design reduces commissioning time and eliminates the need for circuit shutdowns during retrofit, lowering labor costs. The 1-year warranty and durable construction minimize maintenance events, while reliable measurement improves energy billing accuracy and supports demand management programs. Overall, you gain faster deployments, fewer calibration issues, and better long-term energy visibility.
