It is designed for motor protection duty, with phase failure detection and screw-type terminals for both main and auxiliary circuits. ## What the ratings mean for fit The 0.16 A continuous current rating sets the motor full-load current this breaker protects — size it to the motor nameplate FLA, not the supply. Trip Class 10 means the bimetal trips within 10 seconds at 7.2× rated current, standard for standard-duty induction motors starting unloaded or with low-inertia loads. The 100 kA breaking capacity at 400 V is the fault current it can safely interrupt without welding contacts or rupturing the case; this is the SCCR for the branch circuit, so verify the available fault current at the panel is at or below this value. ## Mounting and integration Snap-on mounting onto a 35 mm DIN rail per DIN EN 50022. The 45 mm width takes one standard module slot. Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded; auxiliary control circuit terminals are also screw-type. IP20 on the front means finger-safe from the panel face but not protected against dust ingress into the enclosure — mount inside a rated cabinet. ## Lifecycle and sourcing The lifecycle stage is listed as current production. This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No official successor has been issued for this order code.","metaTitle":"Siemens 3RV1021-0AA15-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0AA15-ZW98 SIRIUS motor protection circuit breaker, 0.16 A continuous, Trip Class 10, 100 kA breaking capacity at 400 V.
