ETL3-63B is an IP+N Type B RCBO (Residual Current Circuit Breaker with Overcurrent protection) with up to 63A rated current, 230/240V rated voltage, 10kA breaking capacity, and 30mA residualcurrent sensitivity. It features both B and C curve characteristics and provides comprehensive protection against overcurrent, short circuit, and earth leakage, with advanced detection of complex waveforms and smooth DC residual currents.
With its bidirectional power capability, ETL3-63B is especially suited for modern electrical installations and renewable energy applications, ensuring reliable protection for sensitive equipment such as EV chargers, solar panels, and heat pumps.
Advantages
• Superior Leakage Detection: B Type protection detects AC, pulsating DC, smooth DC, and high-frequency residual currents, outperforming standard AC or A types for advanced applications like EV charging and renewables.
• Versatile Tripping Curves: Choose B curve for general residential use or C curve for motors and high-impact loads, ensuring precise overload and short-circuit protection.
• High Breaking Capacity: 10kA rating handles demanding electrical faults, reducing downtime and enhancing system reliability.
• User-Friendly Features: Bidirectional wiring simplifies installation, while visual indicators (red/green for contact position, white/blue for faults) provide quick status checks.
• Energy Efficiency and Safety: Energy-limiting class 3 minimizes damage during faults, with fast residual current off-time (≤0.1s) for immediate protection.
• Durability in Harsh Conditions: IP20 protection, wide temperature range (-25°C to +55°C), and long lifespan (4,000 electrical cycles) make it ideal for indoor residential, commercial, and industrial environments.
• Compliance and Versatility: Meets IEC/EN standards, suitable for homes, offices, factories, and public facilities—perfect for "B Type RCBO installation" searches.
