<p>An arc protection relay, particularly suited for use in 42 volt automotive systems applications has input terminals for connection to an external power source; output terminals for connection to an inductive load; a contact connected in series to the input terminal and the output terminal; a relay coil connected to the input terminals and operatively connected to the contact; and at least one energy absorbing device, such as a metal-oxide varistor or a transient surge suppressor, connected in parallel with the output terminals for absorbing fluctuating reverse voltage from the output terminals and optionally contains a second energy absorbing device in the form of a coil suppressor for protecting the coil from voltage surges and a magnet operatively positioned to blow an arc from the contact.</p> |
