The Siemens 5SU9336-7CR06 is a 1P+N RCBO (residual current circuit breaker with overcurrent protection) rated at 6 A with a C-trip characteristic, 30 mA Type A residual sensitivity, and a 6 kA breaking capacity at 230 V AC. The Type A detection means it catches pulsating DC fault currents from single-phase rectified loads — think switched-mode power supplies, LED drivers, or VFD front-ends — not just pure sine-wave AC leakage. The C-curve holds for motor and lighting inrush up to 5–10× rated current, so it won't nuisance-trip on a small pump or a bank of fluorescents.
Snap-on DIN rail mount for a standard distribution board or sub-distribution panel. 1 module width (18 mm) per pole — fits alongside other Siemens 5SU9 series RCBOs and MCBs in a shared enclosure.
