Provided is an apparatus, such as an arc mitigating device, that includes an annular body that defines a lumen and a longitudinal axis, the annular body having a body length along the longitudinal axis. An electrode can be disposed coaxially within the lumen. The electrode may extend into the body by an electrode length that is at least about 50% of the body length, and may have diameter less than or equal to about 50% of an inner diameter of the annular body. An ablative material portion can be disposed between the annular body and the electrode. The annular body and the electrode may be configured such that when an arc exists between the annular body and the electrode, the ablative material portion undergoes ablation and thereby generates a plasma.
