Its A-release is set at 16…22 A, and the short-circuit release trips at 286 A, making it suitable for protecting motor feeders and distribution circuits in control panels where the upstream device coordinates with this trip curve. The screw-terminal termination and standard switching capacity suit fixed-panel builds where DIN-rail mounting is the norm — the S0 footprint fits the standard 45 mm wide slot on the rail, leaving room for auxiliary contact blocks or a separate overload relay downstream. The part carries RoHS compliance from October 1, 2009, and a REACH Article 33 duty-to-inform declaration for lead titanium zirconium oxide (CAS 12626-81-2) above 0.1% w/w. No UL or IEC certification numbers are listed in the available record, so verify site-specific approval requirements against the full manufacturer declaration.","metaTitle":"Siemens 3RV2021-4CA10-0DA0 SIRIUS 3RV2 Circuit Breaker, 16…2","metaDescription":"Siemens 3RV2021-4CA10-0DA0 SIRIUS 3RV2 motor starter protector, size S0.
