All ratings are for 40

C motor ambient,110

C case and 60

C amplifier ambient. For extended ratings at lower ambients contact Allen-Bradley.

The motor contains two thermal switches wired in series that will open on an overtemperature condition. They are set to open at 150

C (typical) and

close at 90-100

C (typical). Contacts are rated for 1A at 115V AC, 1A at 24V DC.

–10% line voltage maximum.
