The corresponding trip setting is at 13 times the minimum LA value shown. Where a 13 times setting is required for an intermediate LA value, alternate cam settings and/or MP ratings should be used. or applications, actual trip levels are approximately 40% higher than values shown. s above 130 amperes are for special applications. N Article (a) requires the ampere rating of the disconnecting means to be not less than 115% of the motor full load ampere rating.

The MP is designed to comply with the applicable requirements of Underwriters Laboratories Standard UL489, anadian Standards Association Standard 22.2 No. 5.1, and International lectrotechnical ommission Recommendations I An innovative design of internal components allows higher MP-starter combination interrupting ratings. The MP is marked to permit proper electrical application within the assigned equipment ratings. The MP is a recognized component (UL ile 7819) and complies with the applicable requirements of Underwriters Laboratories Standard UL489. It is also designed to comply with the applicable requirements of anadian Standards Association Standard 22.2 No. 5.1, International lectrotechnical ommission Recommendations I 157-1, and nameplates bear the marking. Note: Interrupting ratings are dependent on starter it is used with. See R 278. or more information contact utler-ammer at: AT.01.T.

5 - Internal Accessories Auxiliary Switch Vol. 1, Ref. No. [028] Auxiliary Switch The Auxiliary Switch provides circuit breaker contact status information by monitoring the position a of the molded cross bar which contains the moving contact arms. The auxiliary switch is used for b remote indication and interlock system verification, and consists of one or two SPT switches housed in a plug-in module. ach SPT switch has one a and one b contact. When the circuit breaker contacts are open, the a contact is open and the b contact is closed. Table rame lectrical Rating ata ndurance: 0 electrical operations plus 4000 mechanical operations.
