Eaton CT-SP-4-200-5A Current Transformer - ANSI/IEEE C12.20
Part Number: CT-SP-4-200-5A
Quick Summary
The Eaton CT-SP-4-200-5A current transformer provides precise metering for 200 A mains. Facilities face accuracy challenges and downtime from improper CT selection, which can drive energy waste and risk of mismetering. ANSI/IEEE Std C12.20 certification and RoHS compliance support regulatory acceptance in critical environments. With a 5A secondary, split-core design, and 0.5% accuracy, installation is faster and data quality is reliable. This makes it ideal for energy management dashboards, protection relays, and retrofits in manufacturing lines, data centers, and commercial electrical rooms.

The split-core design enables fast installation around existing conductors, reducing project downtime and service interruptions. Economically, it improves project timelines and lowers labor costs while maintaining measurement integrity for critical loads. The CT-SP-4-200-5A delivers a 200 A primary with a 5 A secondary and 0.5% accuracy, providing dependable metering for energy dashboards and control relays in industrial and commercial settings. Burden management is optimized with 2.1 VA ±0.5%, ensuring stable readings even as loads shift. Rated for up to 600 V, it supports modern panels and distribution boards without sacrificing safety margins. RoHS compliance and ANSI/IEEE C12.20 certification offer regulatory peace of mind, while the compact form-factor—window 1.30" x 1.70"—facilitates retrofits in crowded enclosures. The one-year warranty from installation or eighteen months from shipment reduces ownership risk and supports long-term maintenance planning.

FAQs
The CT-SP-4-200-5A uses a split-core design that allows installation around a single conductor without fully powering down. Open the housing, clamp the conductor inside the window, and connect the 5 A secondary leads. Confirm the window size of 1.30" x 1.70" fits your panel opening and ensure the load remains within the 0.5% burden specification for accurate readings.
Key specs include 200 A primary rating with a 5 A secondary, and 0.5% accuracy at full load. Burden is rated at 2.1 VA ±0.5%, and the device supports up to 600 V input. These figures directly translate to reduced metering error, tighter revenue-grade measurements, and improved reliability for energy dashboards and utility-grade meters.
Yes. Its split-core design and 1.30" x 1.70" window enable quick retrofits in crowded panels. With a 200 A primary and 5 A secondary, it integrates with standard meters and protection relays. Compliance with ANSI/IEEE C12.20 and RoHS helps ensure regulatory compatibility in varied facilities, from manufacturing floors to data centers.
The CT-SP-4-200-5A carries ANSI/IEEE Std C12.20 certification for accuracy in energy measurement and RoHS compliance for hazardous material restrictions. It also carries Eaton’s warranty terms (one year from installation or 18 months from shipment), supporting risk mitigation and service planning in regulated environments.
ROI stems from faster installations, reduced downtime, and lower labor costs due to the split-core design. Improved measurement accuracy (0.5%) minimizes billing discrepancies, aiding energy-management initiatives. Regulatory compliance reduces audit risk, while the rugged temperature range (-10 to 60 C) and RoHS support long-term reliability with minimal maintenance.
