Accessories Selection Guide and Ordering Guide
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, K-Frame circuit breaker line and load terminals are shipped separately for field installation.
Ordering Information
K-Frame circuit breakers use Cu/AI terminals as standard. When optional copper or Cu/ AI terminals are required, order by catalog number. Specify if factory installation is required.
