* Interrupting ratings (Interrupting ratings for 125mA - 3A were measured at 70% - 80% power factor on AC. The interrupting ratings for 4A were measured at 100% power factor on AC)
** Typical DC Cold Resistance (measured at <10% of rated current)
† Typical Melting I2t (I2t was measured at listed interrupting rating and rated voltage)
‡ Typical Voltage Drop (voltage drop was measured at 20°C ambient temperature at rated current)
