Product Features of the Type A or Type AC RCBO

Constructed for rigorous electrical environments, this Type A or Type 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 (ETL3-63H), effortlessly clearing high-inrush fault currents.
Advanced Visual Diagnostics: Integrates a blue/white residual current trip indicator alongside a red/green contact position window for instant, error-free fault recognition.
Flexible Wiring Architecture: Fully supports bidirectional power routing and accepts cables up to 25mm² (rigid) alongside standard pin and fork-type busbars.
Eco-Conscious Durability: Built from premium halogen-free, RoHS-compliant thermoplastics, ensuring structural integrity and a massive 8,000-cycle mechanical lifespan.

Tripping Sensitivity Applications

Select the precise sensitivity rating (IΔn) to match specific personnel and equipment protection requirements.

Sensitivity Ratings (IΔn)
10mA	Provides a higher level of protection for the human body, used in situations with very high requirements like swimming pools and humid environments.
30mA	Most commonly used for personnel protection in homes and commercial buildings, suitable for general socket protection.
100mA	Usually used in situations where personal protection is less strict, focusing heavily on equipment protection like air conditioning systems.
300mA	Mainly used for superior fire protection, acting as general protection for massive distribution boards.
