Question

Quizplus · Accepted Answer

Interruption of large currents by a relay requires arc suppressing blow out coils to manage the arc produced when contacts open, wide separation of the opened contacts to ensure the arc does not re-ignite, and high-speed opening of contacts to minimize the duration of the arc and reduce damage or wear to the contacts.
