Product Features of the Type A or AC RCBO

Engineered to instantaneously interrupt 240/415V AC system faults, this Type A or AC RCBO guarantees rigorous equipment safety and personnel protection.

Dual Protection: Functions as a highly dependable rccb with overcurrent protection against overload, short circuit, and residual leakage faults.
High-Capacity Disconnection: Safely clears conditional short-circuit faults up to 6kA for the standard ETL3-63M, and 10kA for the heavy-duty ETL3-63MH variant.
Visual Fault Indication: Features a transparent trip status observation port alongside a visual leakage fault indication window (White for Normal, Blue for Leakage) to accelerate panel maintenance.
Wiring Versatility: Supports bidirectional incoming routing, seamlessly accommodating 16mm² flexible or 25mm² rigid cables simultaneously with PIN/Fork busbars.

Field Applications for AC Distribution

Deploying the ETL3-63M model minimizes critical downtime across specialized commercial and industrial architectures.

Industrial Equipment: Secures automated power supply lines against composite electrical leakage and overloads using the Type A or AC RCBO.
Commercial Buildings: Isolates multi-frequency faults effectively within complex lighting circuit control systems.
Public Facilities: Maintains strict electrical safety assurance in high-traffic environments requiring rapid 30mA to 300mA sensitivity responses.
Residential Distribution: Acts as the primary main circuit protection device for high-density housing load centers.
