The A-release is set at 0.55...0.8 A and the short-circuit release trips at 10 A. It uses screw terminals and offers standard switching capacity — a direct fit for motor branch circuits in a control panel where the motor full-load current falls within that 0.55–0.8 A window. Size S0 snaps onto a DIN rail in the panel — standard 45 mm width per the S0 frame. The screw terminals accept copper conductors typical for motor circuits in this current class. Packaging dimensions are 102 x 49 x 102 mm, so plan for that footprint when laying out the enclosure. RoHS compliant since October 2009, and REACH candidate-list information is available on request.","metaTitle":"Siemens 3RV2021-0HA10-0DA0 SIRIUS 3RV2 Motor Starter Protect","metaDescription":"Siemens 3RV2021-0HA10-0DA0 SIRIUS 3RV2 circuit breaker, size S0, A-release 0.55-0.8 A, short-circuit release 10 A, screw terminal.
