That is a consistent fault-clearing capability that covers most industrial low-voltage distribution systems without needing an upstream current-limiting device. No ground-fault detection here — that is handled separately if your circuit requires it. Depth is 96 mm from the rail surface to the front of the breaker. ## Terminal wiring Main circuit terminals accept solid conductors 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), and stranded conductors 2x (1... 2.5 mm²) or 2x (2.5... 6 mm²). AWG equivalents for the main contacts are 2x (14... 10). Auxiliary and control circuit terminals are also screw-type, with the same solid and stranded ranges.","metaTitle":"Siemens 3RV1021-0FA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV1021-0FA15 motor protection circuit breaker, 0.5 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V AC.
