Accessories Selection Guide and Ordering Information
Line and Load Terminals
Eaton’s line and load terminals provide wire connecting capabilities for specific ranges of continuous current ratings and wire types. All terminals comply with Underwriters Laboratories Standards UL 486A and UL 486B and CSA Standard C22.2 No. 65, or Electrical Bulletin 1165. Unless otherwise specified, JFrame circuit breaker line and load terminals are shipped separately for field installation.
The bottom of the standard TA250KB terminal contains a recess that is positioned over the J-Frame circuit breaker terminal conductor.
Ordering Information
J-Frame circuit breakers use Cu/AI terminals as standard. When optional copper-only terminals are required, order by catalog number. Specify if factory installation is required.
