Although this circuit uses two contactors, it is critical that they can. This can be accomplished using a pair of contactors, or a special inter-linking set of contactors which is appropriately called a ‘reversing contactor.’. Available in a number of current ratings from 6A to 65A, reversing contactors are available in 2 pole and multi-pole versions to meet any set of requirements. The concept of three-phase electricity allows you to simply interchange two of the three-phase lines into the motor. Reversing starters with bimetal overload protection can be assembled from TeSys N reversing contactors and TeSys D overload relays.
Starters come with Motor Logic Class 10/20 selectable solid-state overload relays as standard. Reversing motor contactors can be either IEC or NEMA rated for use across applications such as infrastructure, building and other industrial applications that requires the motor to run in reverse. Reversing starters are mechanically and electrically interlocked and are available in NEMA Sizes 00 through 5. What type of reversing contactor is right for you? They have two interlocked contacts and are designed to prevent the motor from running forwards and backwards simultaneously. The type of current itself is not a factor, as both AC and DC contactors can be reversing contactors. The concise reversing contactor definition.Ī reversing contactor simply reverses the polarity of the current by reversing the motor leads, causing the motor to run in the opposite direction.
