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.
