1. The minimum breaking capacity is 400% rated current under rated voltage 

2. DC cold resistance is measured at <10% of rated current in ambient temperature of +25 °C; the test point is on the position of the terminal close to the body 

3. Typical pre-arcing I[2] t is measured at interrupting voltage and current 

## **Dimensions - mm** 

The recommended torque for installation is 12 ± 1 Nm (M8)
