* Interrupting ratings: Interrupting ratings for 63mA - 6.3A were measured at 70% - 80% power factor on AC. The interrupting ratings for 7A - 10A were measured at 100% power factor on AC. 

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

- Typical Pre-Archin2tg ( **I** 2t was measured at listed interrupting rating and rated voltage) 

‡ 

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