YTLQ10-XX 10Kv airtight three-phase AC current sensor
1. Introduction:
YTLQ10-XX series current sensors detect current based on LPCT principle, three-phase integrated structure, epoxy resin casting, fully enclosed insulation, safe and reliable, suitable for common box outdoor pole-mounted circuit breakers with good anti-condensation performance (ZW20) Or outdoor pole-mounted load switch (FZW28) installation, suitable for current measurement (metering) and protection in AC 50/60Hz lines with the highest voltage of 12kV and below.

2. Product Features:
YTLQ10-XX series current sensors are based on the principle of low-power coils. Compared with traditional transformers, they have the following advantages:
1. Integrates 3 phase current and 1 zero-sequence current sensors, small in size, light in weight, easy to install and use
2,. The secondary output is a safe low-voltage signal, without the risk of secondary open-circuit high voltage, increasing safety
3. The power consumption is greatly reduced and the heat generation is small
4. Standardized products, simplified selection and ordering process, and fast delivery
