How do you calculate the wear level of TeSys Giga contactor ? By calculating the on/off time ? Why is opening speed better than opening time ?

Question

Accepted Answer

Contact tips wear rate of is linked to the opening speed and not the opening time. Our algorithm is based on this concept with a dedicated electronic circuit.
Arc Voltage is a function of contact separation speed. And Wear Rate is a function of Arc Energy.
