Its thermal overcurrent release (A-release) is set at 0.22...0.32 A, and the magnetic short-circuit release trips at 4.2 A. This means the breaker is sized for a small motor or transformer primary — the 4.2 A magnetic trip clears a hard fault fast, while the 0.22-0.32 A thermal band protects the downstream winding from sustained overload. Screw terminals, standard switching capacity. The packaging dimensions — 101 x 52 x 104 mm — give the envelope for panel layout; allow clearance above and below for screw-terminal access and the manual reset actuator. Group code R711 and product group 5333 are Siemens internal cataloguing fields that help trace the part in their system if you need a cross-reference or a multi-year BOM freeze check.","metaTitle":"Siemens 3RV2021-0DA10-0DA0 SIRIUS 3RV2 Motor Starter Protect","metaDescription":"Siemens SIRIUS 3RV2021-0DA10-0DA0 circuit breaker, size S0, 0.22-0.32 A thermal, 4.2 A magnetic.
