* Interrupting ratings measured at 70% - 80% power factor on AC. The interrupting ratings for 18A and 20A were measured at 85% - 95% power factor on AC. The interrupting ratings for 25A and 30A were
measured at 89% power factor on AC.
** Typical DC cold resistance measured at <10% of rated current.
† Typical melting I

t measured at listed interrupting rating and rated voltage.
‡ Typical voltage drop measured at 25°C±3°C ambient temperature at rated current.
‡‡ CSA approvals for 25A and 30A are at 125Vac - IR 1000A and 125Vdc - IR 400A (IR 1000A at 75Vdc)
