- 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. 

- ** DC Cold Resistance (Measured at <10% of rated current) 

- Typical Pre-Arching I[2] t (I[2] t was measured at listed interrupting rating and rated voltage) 

- Maximum Voltage drop (Voltage drop was measured at 20°C ambient temperature at rated current)
