Product Features of the Type A And AC RCBO

Constructed for rigorous environments with non-linear loads, this Type A And AC RCBO leverages a precise electronic ground fault trip mechanism paired with a robust thermal-magnetic core.

  • Dual Leakage Detection: Effectively detects standard sinusoidal AC residual currents (Type AC) alongside pulsating DC leakage currents below 6mA (Type A).
  • High Short-Circuit Defense: Achieves a formidable 6kA rated short-circuit capacity (Icn) or an upgraded 10kA (ETL5-63H), effortlessly clearing massive high-inrush fault currents.
  • Advanced Visual Diagnostics: Integrates a distinct residual current trip indicator alongside a red/green contact position window for instant, error-free fault recognition.
  • Flexible Wiring Architecture: Designed for top incoming wiring, accepting cables up to 25mm² (rigid) alongside standard pin and fork-type busbars on the line side.
  • Eco-Conscious Durability: Built from premium halogen-free, RoHS-compliant thermoplastics, ensuring long-term structural integrity and a massive 10,000-cycle mechanical lifespan.
