Notes: - The arc switching on DC is more difficult than on AC
- For information, typical time constant values are quoted hereafter: non inductive loads such as resistance furnaces: L/R < 1 ms; inductive loads such as shunt motor:
L/R < 2 ms; series motor: L/R < 7.5 ms
- The addition of a resistor in parallel with an inductive winding helps in the elimination of the arcs
- All the poles required for breaking must be connected, in series, between the load and the source polarity not linked to the earth
- Connection of the poles in series by the user, according to the above diagrams. The connection of the poles in series helps in the elimination of the arcs
- These characteristics are suitable for IOR..CC-AME contactor latching versions (except for mechanical durability = 0.2 millions of operating cycles).
