Westhomes WSB9L‑125 RCCB for EV Charger
Rated for 230 V AC, 100 or 125 A with 30 mA residual current trip. Provides earth leakage, overload & short‑circuit protection. Compliant with IEC 61009‑1 and GB/T 16917 standards. Ideal for residential and commercial EV charging.
The WSB9L‑125 series is engineered for electric vehicle charging systems, delivering reliable protection at AC 230 V, with rated currents of 100 A or 125 A and a fixed 30 mA residual operating current (IΔn). It provides safety against electric shock via earth leakage detection, along with overcurrent and short‑circuit protection—while also supporting infrequent manual switching of power lines. Its robust design is ideal for residential, commercial, and industrial EV charger installations.
Key Features:
Precision leakage detection minimizes risk of shock—meets safety codes for EV platforms
Comprehensive protection in one device: earth leakage (ELCB / RCCB), overcurrent, and short-circuit
High-rated current options (100/125 A) support powerful charging stations
Modular DIN‑rail design allows straightforward integration and maintenance
Global compliance with IEC & GB standards ensures reliability across markets
Applications
Designed specifically for electric vehicle charging stations, the WSB9L‑125 delivers vital safety features in EV infrastructure. Its robust performance and international certifications make it ideal for use in residential EV chargers, commercial charge points, hotels, and light industrial sites.
