Features 30mA sensitivity for personal shock protection, C-curve magnetic tripping (5–10× rated current), and 10kA breaking capacity for heavy-duty fault protection. Type A leakage detection handles both AC and pulsating DC residual currents, ideal for modern electronic loads. Mounts on standard 35mm DIN rail with top or bottom cable entry. Certified to IEC\/EN 61009-1.
