Product overview
The VTEKE VST Series Summation Current Transformers are designed to combine the secondary currents of multiple current transformers into a single output for centralized current measurement. The series enables currents from different feeders or electrical loads to be monitored through one measuring instrument, with configurations supporting up to nine current transformer inputs.
Applications
- Summation of currents from multiple feeders
- Centralized current measurement
- Electrical distribution panels
- Industrial power monitoring systems
- Multi-feeder electrical installations
Key features
- Summation of multiple current transformer secondary signals
- Up to 9 current transformer inputs
- Suitable for equal or unequal primary CT ratios
- Secondary output options of 1 A or 5 A
- DIN rail mounting
- Protected connection terminals
- Compact design for electrical panels
