WLCT Three Phase Current Transformer
WLCT Three Phase Current Transformer
Description
WLCT Three Phase Current Transformer
The WLCT three-phase current transformer is designed for accurate current measurement and protection in low-voltage intelligent switchgear systems. With a standardized 5A secondary output and 5P10 protection class, it delivers reliable performance across a wide range of industrial power applications.
Lead Wire Configuration
The WLCT lead wire is available in four standard lengths: 0.5m, 1m, 2m, and 3m. The left-end terminal connects to the main device body; the right-end terminal connects to the WLCT-*A three-phase current transformer. Naming convention: *CT*X-0.5 = 0.5m, *CT*X-1 = 1m, *CT*X-2 = 2m, *CT*X-3 = 3m.
