Allen Bradley Overload Relay Heater Tables For Bulletin 709 & 509

The Allen Bradley heater tables below are two of the most common used for sizing standard overload relay protection for Type N and type W heater elements.  The old style type N heater elements are used with Bulletin 709 motor starters and Overload Relay Blocks.  While the Type W heater elements are used with current Bulletin 509 motor starters and Overload Relay Blocks. 

The tables provide heater elements for Class 20 operation and are recommended for General Applications.  The "Full Load Amps" listed in the tables are to be used for heater element selection.  The rating of the relay in amperes a 40 C is 115% of the "Full Load Amps" listed for the Heater Number.

Note:  To select heater elements for non standard applications including those where the motor starter and the motor being controlled are not at the same ambient temperature, give us a call and talk to one of our knowledgeable sales staff who can help you with making the correct heater selection.
