Product Description
Product Overview
SCTK661 Series split-core current transformers feature a retro-fit design for easy installation in both new and existing electrical networks. These transformers can be installed without interrupting cable or bus-bar circuits, with an internal precision resistor providing a safe 0.333V output voltage.
Key Features
- Self-locking structure for safe, portable installation
- Split-core design with interleaved joint and hinge structure
- Wide inner window accommodates large cables and bus-bars
- Measurement range: 0.5-630A AC input, 0-0.333V/0-500mA output
- Compatible with single-phase and anti-tampering electricity meters
- Multiple mechanical dimensions for customized installations
- Reduces installation time and costs
Applications
Current measurement, monitoring, and protection for electrical wiring and equipment. Suitable for electric motors, lighting systems, air compressors, HVAC equipment, automation control systems, and relay protection devices.
