FAQs
CT-SP-6-400-5A is designed for common LV panel installations that accept split-core current transformers. The 5.50 x 2.00 inch window accommodates typical conductor sizes, and the two-wire secondary simplifies wiring to metering devices. Its 600 V rating and 400 A primary support integration with most distribution panels, meters, and energy management systems without requiring circuit isolation.
Key specs include 400 A primary rating with a 5 A secondary, 1.0% accuracy class, 600 V input voltage, and a burden of 2.75 VA. The device uses two wires and provides reliable measurements under -10°C to 60°C. These figures translate to accurate energy data for billing, submetering, and real-time monitoring.
Yes, the CT-SP-6-400-5A is intended for 400 A primary currents, with a robust split-core design that clamps around existing conductors. It maintains accuracy across typical industrial contexts while meeting RoHS environmental standards. For very high-frequency transients or arcing environments, ensure proper installation and shielding of the conductor leads.
Certification includes ANSI/IEEE Std C12.20 for metering accuracy and RoHS compliance for environmental safety. These credentials support regulatory conformance in process and manufacturing environments and help meet energy-management standards. The unit’s burden and Class 1.0 performance further reinforce reliability in utility-grade metering and panel installations.
The CT-SP-6-400-5A reduces commissioning time thanks to its split-core clamp, lowering labor costs during retrofits or panel upgrades. Its durability, warranty terms, and RoHS compliance minimize regulatory and replacement risks. Maintenance is straightforward: periodically inspect connections, ensure clean terminals, and verify output signals align with metering data.
