Its 100 kA breaking capacity at 400 V AC (and at 240 V, 500 V, and 690 V AC) means it safely interrupts fault currents up to that level without cascading upstream — a figure that holds the unit on the grid for high-fault-capacity industrial panels, provided the upstream protective device is coordinated. ## DIN rail integration and wiring At 45 mm wide, 97 mm tall, and 96 mm deep, this breaker occupies a single 45 mm module on the DIN rail — a standard footprint for SIRIUS motor protection breakers, so it fits existing panel layouts without re-spacing. The main circuit uses screw-type terminals accepting solid conductors of 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), or stranded 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). The auxiliary switch is transverse design, with zero auxiliary contacts fitted as standard — if you need aux contacts, they are added separately. Clearance: 0 mm backwards and 0 mm at the side, so no extra air gap is required between units on the rail — you can pack them tight. Shock resistance is 25g for 11 ms. ## Auxiliary switching and contact ratings An auxiliary switch is present (transverse design), rated at 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V — these are the switching capacities for the auxiliary contact block, not the main motor circuit. Mechanical endurance of the main contacts is typically 100 000 operating cycles. Maximum switching frequency at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1021-0AA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0AA15 SIRIUS motor protection circuit breaker, 0.16 A rated current, CLASS 10 trip, 100 kA breaking capacity at 400 V AC.
