The Siemens 5SU1636-7FP10 is a 3-pole RCBO (residual current circuit breaker with overcurrent protection) rated 10 A at 400 V, with a C-trip characteristic and 300 mA residual sensitivity Type A. Breaking capacity is 6 kA. This is a current-production part — lifecycle status is active.
The 300 mA residual sensitivity (Type A) detects pulsating DC fault currents as well as sinusoidal AC, which covers modern electronics with half-wave rectification. At 10 A per pole and 400 V line-to-line, this RCBO fits a 3-phase subfeed or final circuit where combined overcurrent and earth-fault protection is required in one DIN-rail module.
