Eaton CT-SP-5-600-5A – Frequently Asked Questions
1) What is this Eaton CT-SP-5 current transformer used for?
This split-core current transformer monitors electrical current in power distribution systems. It clamps around existing conductors without disconnecting circuits. Common applications include metering panels, motor control centers, and switchboards.
2) What does the 600:5A ratio mean?
The 600:5A ratio means the CT steps down 600 amps of primary current to 5 amps secondary output. This allows standard 5A meters and relays to monitor high primary currents safely. At 600A primary load, the secondary outputs exactly 5A.
3) What conductor sizes fit through this split-core CT?
Check the manufacturer's specifications for exact window dimensions. Most 600A-rated split-core CTs accommodate large conductors or multiple smaller conductors. Verify your conductor diameter fits the internal window before ordering.
4) Can this CT work with different metering equipment?
Yes, this 5A secondary output works with standard power meters, protective relays, and monitoring systems designed for 5A CT inputs. Verify your equipment matches the 5A rating and 0.5% accuracy class requirements.
5) What does 0.5% accuracy class mean?
The 0.5% accuracy means the CT maintains measurement precision within 0.5% error at rated conditions. This accuracy class suits revenue metering and precise monitoring applications where high accuracy is required.
6) How do I install this split-core current transformer?
Open the split-core housing and clamp around the primary conductor. Ensure proper contact at the split joint. Connect secondary leads to your meter or relay. Follow NEC requirements for CT secondary grounding and never leave secondary terminals open.
7) What's the operating temperature range?
This CT operates from -10°C to +60°C (14°F to 140°F). This range covers most indoor electrical environments. For extreme temperature applications, verify your installation stays within these limits for accurate performance.
8) Does this CT require maintenance?
Minimal maintenance required. Periodically inspect the split-core joint for tight contact. Check secondary connections for corrosion or looseness. Clean accumulated dust that might affect heat dissipation around the CT housing.
9) Can I use this CT for single-phase or three-phase systems?
This CT works on individual conductors in both single-phase and three-phase systems. For three-phase monitoring, you typically need three CTs (one per phase). Install each CT on its respective phase conductor.
10) What's the maximum primary current this CT can handle?
The 600A rating is the maximum continuous primary current for accurate operation. Short-term overloads may be acceptable per manufacturer specifications. Exceeding rated current reduces accuracy and may damage the CT.
11) Are there other CT ratios available in this series?
The CT-SP-5 series typically offers multiple ratios for different current ranges. Check our Eaton products section for other ratios like 100:5, 200:5, 400:5, or 800:5 to match your specific application needs.
12) What safety precautions apply when working with current transformers?
Never open CT secondary circuits while primary current flows - this creates dangerous high voltages. Always short secondary terminals before disconnecting meters. De-energize circuits when possible during installation. Follow lockout/tagout procedures.
