Relay Dc Contact Rating. Relay manufacturers data sheets give maximum contact ratings for resistive dc loads only and this rating is greatly reduced for either ac loads or highly inductive or. We’ll explore the similarities and differences between ac and dc contact ratings of electric switches and electromechanical relays. There are ratings for general purpose and resistive; But prior to discussing the contact. The relay user should select contact materials, ratings, and. The general purpose rating is for ac, and it will break as much as 240v ac. If a data sheet for a relay series makes no mention of dc contact current rating and conditions for a specific relay or relay. Which one do i take into account? There is no such thing as a universal contact. In general, instrument grade reed relays have the longest mechanical life. Relay contacts are available in a variety of metals and alloys, sizes and styles. Reed relays and electromechanical relays (emrs). I need to determine if a relay with a contact rating of 10a 250vac/30vdc can handle 25a at 12vdc and if it would be able to handle. There are two types of mechanical relays:
