Product Description
Product Overview
The SCTK661 Series AC 0.333V Split Core Current Transformers are designed for easy installation in both new and existing electrical networks. These split-core transformers can be installed without interrupting cable or bus-bar circuits, featuring an internal precision resistor that provides a safe low-voltage output.
Key Features
- Self-locking structure for safe and easy installation
- Split core design with interleaved joint and hinge construction
- Wide inner window accommodates large cables and bus-bars
- Measurement range: 0.5A to 630A AC input, 0-0.333V or 0-500mA output
- Suitable for single-phase and anti-tampering electricity meters
- Multiple mechanical dimensions for various installation requirements
- Reduces installation time and costs significantly
Applications
Current measurement, monitoring, and protection for electrical wiring and equipment. Power measurement for electric motors, lighting systems, air compressors, HVAC equipment, and automation control systems. Current, power, and energy monitoring devices. Relay protection systems.
