Type-A RCCB for EV Charging Stations: 50kA Breaking Capacity with Dual Inlet Flexibility

1. Core Features & Technical Excellence

GreenWatt®’s Type-A Residual Current Circuit Breaker (RCCB) is engineered to address the critical safety demands of electric vehicle (EV) charging infrastructure. Designed for 50kA breaking capacity and dual inlet compatibility (top/bottom entry), it ensures robust protection and adaptability in high-power charging environments.  

Key Specifications:

- 50kA Short-Circuit Protection: Exceeds standard RCCB ratings, safeguarding DC fast-charging stations (e.g., 150kW+ systems) against catastrophic faults, minimizing fire risks and equipment damage.  

- Dual Inlet Design: Supports both top-entry (overhead cable trays) and bottom-entry (underground conduits), reducing installation complexity by 30% in confined spaces like urban charging hubs.  

- Precision Leakage Detection: Identifies AC and pulsating DC residual currents (30mA–500mA), complying with IEC 60947-2 standards, crucial for Tesla Superchargers and bidirectional charging systems.  

- Durability: V0 flame-retardant housing withstands extreme temperatures (-40°C to +85°C) and corrosive coastal climates, ensuring longevity in Middle Eastern deserts or Nordic winters.  

2. Applications in EV Charging Infrastructure

Type-A RCCB is indispensable across diverse charging scenarios:  

1. Public Fast-Charging Networks: Ensures safety in high-traffic areas (e.g., highways, shopping malls) where rapid fault interruption is critical to prevent cascading failures.  

2. Residential & Commercial Chargers: Compatible with wall-mounted or pedestal designs, offering flexibility for home garages or office parking lots.  

3. Fleet Charging Depots: Withstands frequent plugging cycles in logistics centers, reducing downtime through tool-free maintenance access.  

3. Innovative Design & Certifications

- Dual CT Magnetic Balance Technology: Eliminates false tripping in high-harmonic environments (THD >40%), common in solar-powered charging stations.  

- Modular Accessories: Integrates remote shunt releases for emergency shutdowns and auxiliary contacts for real-time status monitoring via building management systems (BMS).  

- Global Compliance: Certified by CB and IEC 660947-2, meeting stringent safety requirements for EV charging equipment worldwide.  

4. Market Positioning & Customer Value

- Cost Efficiency: Reduces system downtime by 40% compared to conventional RCCBs, lowering total ownership costs for charging operators.  

- Custom Solutions: ODM services for branding, voltage thresholds, and communication protocols

- Rapid Delivery: Local stockpiles in Dubai and Europe ensure 7-day lead times for urgent projects.  

Conclusion

GreenWatt®’s Type-A RCCB redefines safety and flexibility for EV charging systems, combining 50kA fault interruption, dual inlet versatility, and IoT-ready features. Trusted in Dubai’s Green Charger Initiative and European microgrids, it delivers unmatched reliability for tomorrow’s energy ecosystems.
