LZW32-10G type Outdoor Inverted Current Transformer
Product Functions
◆Precise Current Measurement: Serves as a multi-turn current transformer with a small transformation ratio, accurately converting primary currents (10~600A) to a standard 5A secondary output for reliable metering and protection.
◆Protection & Metering Integration: Provides dual-class accuracy (0.2S for precise energy measurement and 10P20 for reliable protection relay operation), enabling simultaneous use for both billing and circuit protection functions.
◆Seamless System Integration: Specifically designed for dedicated use with ZW32(43)-10 vacuum circuit breakers, ensuring easy installation, optimal compatibility, and stable performance within the switchgear assembly.
Applicable Environment
◇Primary Application: Optimized for outdoor electrical distribution systems, particularly in pole-mounted or ground-installed switchgear configurations incorporating ZW32(43)-10 vacuum circuit breakers.
◇Industrial Use: Ideal for grid distribution networks, renewable energy connections (like solar or wind farm step-up points), and industrial plant feeder circuits requiring outdoor current sensing.
◇Environmental Resilience: Built to withstand harsh outdoor conditions, operating reliably within an ambient temperature range of -25℃ to +45℃, suitable for various climatic regions.
Product Highlights
