Effective Shortening of Break Arc Duration s of Ag and Several Ag-based Contacts in DC Load Conditions with Increased Contact Opening Speeds and External Magnetic Field

Relationships between Break Arc Behaviors of AgSnO₂ Contacts and Lorentz Force to be Applied by an External Magnetic Force in a DC Inductive Load Circuit Up to 20V-17A

“…Figure 1 shows exemplary experimental results of measured break arc duration characteristics of AgSnO 2 contact pairs in an inductive DC load circuit at 14V-12A, 20V-7A and 20V-17A, respectively (Log-log scale versions of these graphs can be found in Ref. [15]). By opening contacts at faster speeds, break arc durations are surely reduced.…”
