For larger contactors, sizes 30 amps and larger,
or if the hand method above is problematic, a small 0.5 x 3mm flat head screwdriver can be used. Insert the tip of the screwdriver between the edge of the front of the auxiliary and side of the contactor. Give a small twist or flex to gently push the top of the auxiliary away from the side of the contactor. Now lift up and away with the other hand. NOTE: Going farther than .030" may result in the breaking of one or both of the two top side locking hooks.
This method applies to side mount auxiliary contacts with part numbers of CA7-PA-*. For complete instructions on all CA7 and CS7 coils and auxiliaries please see the instruction sheets in the Sprecher + Schuh library.
