Product details

Motor protection circuit breaker, CLASS 10, 10–16 A

The Siemens 3RV2021-4AA25-Z X95 is a SIRIUS 3RV2 motor starter protector in size S0, rated for CLASS 10 trip curve with an A-release (overload) set at 10–16 A and an N-release (short-circuit) at 208 A. CLASS 10 means it trips within 10 seconds at 7.2× rated current — fast enough to protect standard induction motors during locked-rotor conditions without nuisance tripping on normal starts. The spring-type terminals accept 0.2–2.5 mm² solid or ferruled stranded wire, matching the DIN-rail panel footprint common in European control cabinets.

RoHS compliant since October 2009. REACH Article 33 duty-to-inform applies: lead (CAS 7439-92-1) above 0.1% w/w in the product. Packaged as 1 piece individually, with bulk pack of 35 units per reusable container.
