⋆ To order contactors (sizes 0…3) with current limiters, change the letter T to D at the end of the listed cat. no. Example: Cat. No. 503-AAÄ-35D.
When controlling high efficiency motors consult your local Rockwell Automation sales office or Allen-Bradley distributor for proper circuit breaker selection.
Ä Coil Voltage Code
The cat. no. as listed is incomplete. Select a Coil Voltage Code from the table below to complete the cat. no.
Example: Cat. No. 503-BAÄ-35T becomes Cat. No. 503-BAB-35T. For other voltages, consult your local Rockwell Automation sales office or Allen‑Bradley distributor.
