摘要： The invention provides a switching device having a contact protection circuit for arcing suppression. The switching device comprises a main relay for interrupting a load path and a dual coil auxiliary having a high resistance coil and a low resistance coil that operate the switching of an auxiliary contact. The auxiliary contact is connected in series with a PTC device and the low resistance coil of the auxiliary relay in a series arrangement. The series arrangement is connected in parallel to the main contact. When the main relay opens, the auxiliary contact is maintained closed during a given time interval due to the magnetic flux generated by the low resistance coil. The given time interval depends on the transition of the PTC device to trip state. In another configuration, the dual coil relay is substituted by two auxiliary relays.
