* Interrupting ratings: Interrupting ratings for 1-15A at 125Vdc was measured at 10,000A, 3.5 ms maximum, with time constant. Ratings 20-30A at 125Vdc were measured at 200A, 0.5 ms
maximum, with time constant. Ratings 1-15A at 125Vac were measured at 10,000A, and 70% - 80% power factor. The interrupting ratings for 1-30A at 250Vac were measured at 90% -
100% power factor.
** DC Cold Resistance (Measured at <10% of rated current)
† Typical Melting I2t (I2twas measured at listed interrupting rating and rated voltage) Interrupting ratings were measured at 70% to 80% power factor on AC.
‡ Typical Voltage drop (Voltage drop was measured at 25°C±3°C ambient temperature at rated current)
