Reliable and High-Quality RCD – Perfect for EV Charging Setup
I purchased the Schneider Electric A9Z21440 Residual Current Circuit Breaker (RCD) to complement the Schneider A9F04332 3P 32A circuit breaker for setting up a three-phase 32A outlet to charge my electric car. As expected from Schneider, the build quality is excellent, and it provides reliable protection for my installation. The 40A rating with 30mA sensitivity (Type A) makes it perfect for EV charging, offering protection against earth faults and ensuring safety for both the charger and the car. The installation process was straightforward, and everything works flawlessly. If you're looking for a reliable RCD for an EV charging setup or any other three-phase application, I highly recommend this Schneider Electric FI-Schalter. It’s a safe, high-performance product that delivers peace of mind.
