Abstract: Systems and methods for contact erosion mitigation are provided. To perform contact erosion mitigation, an order of opening/closing poles and/or contact relays of particular poles is altered, resulting in a sharing of potential arcing conditions amongst the poles/contact relays of these poles.

Abstract: A control system may include a processor that may receive a first dataset associated with a type of load device coupled to a relay device. The processor may then receive a second dataset associated with one or more operations of the load device over a period of time. The processor may also determine a switching profile to control moving an armature of the relay device between a first position and a second position based on the first dataset and the second dataset, such that the switching profile comprises a firing angle for moving the armature with respect to an electrical waveform. The processor may then control a current provided to a relay coil of the relay device based on the switching profile.
