FAQs
The CT-SP-3163-3000-5 uses a split-core design that snaps around a conductor in most standard switchgear and MCC enclosures. Before installation, verify conductor sizing fits within the 3.15 x 6.30 inch window and ensure power is de-energized per site procedures. The device’s 9.72 inch length and 6.93 inch width fit many panel layouts, reducing rework.
0.3% accuracy indicates a high-precision measurement that minimizes energy reporting errors. For metering and energy accounting, this translates to tighter billable consumption data, better demand forecasting, and improved energy management programs. The CT-SP-3163-3000-5 maintains this precision across its 0 to 3000 A primary range with a 5 A output.
Yes. The CT-SP-3163-3000-5 is designed for high-current monitoring in MCCs and panel metering applications. Its split-core design allows retrofits without outages, and its 5 A secondary output is compatible with common metering and control instrumentation. Its compact window fits constrained spaces, simplifying MCC integration.
This current sensor is UL Recognized and CSA Certified, which supports compliance with North American safety and reliability standards. These certifications help reduce procurement risk, ease customer audits, and ensure suitability for industrial installations governed by strict safety requirements.
Maintenance is minimal: once installed, there are no moving parts requiring frequent attention, and the clamp-on design reduces downtime during retrofits. ROI comes from faster installations, improved measurement accuracy, and reduced wiring complexity, enabling quicker commissioning, lower labor costs, and better energy visibility across facilities.
