- Interrupting ratings (500mA to 10A were measured at 70% to 80% PF on. 

- ** Typical DC Cold Resistance (Measured At <10% of rated current). 

- *** Typical Pre-Arching I2t (Measured at listed interrupting rating and rated voltage if not specified). 

- The typical I2t value was measured at 10 times of rated current under DC. 

- Typical Voltage Drop (voltage drop was measured at 20°C ambient temperature at rated current).
