Selection Guide and Ordering Information
Line and Load Terminals
EG-Frame circuit breakers and molded case switches have
line and load terminals as standard equipment.
Table 12-13. Line and Load Terminals
Standard Cu/Al Pressure Type Terminals
Insert collar enclosing conductor as shown. Locate nut on top
of conductor and tighten securely with screw and washer.
Caution: Collar must surround conductor.
Insert collar enclosing conductor and center on extrusion.
Tighten securely with screw and washer. Endcap kits are
used on the E-Frame breaker line side to connect bus bar or
similar electrical connections. Includes hardware.
Control Wire Terminal Kit
For use with steel or stainless steel standard line and load
terminals only.

Base Mounting Hardware
Metric base mounting hardware is included with a circuit
breaker or molded case switch. (Included with breaker.)
Note: English mounting hardware kit can be supplied separate.
Table 12-16. DIN Rail Mounting
Multiwire Connectors
Field-installed multiwire connectors for the load side (OFF)
end terminals. They are used to distribute the load from
the circuit breaker to multiple devices without the use of
separate distribution terminal blocks.
Multiwire lug kits include mounting hardware, terminal
shield insulators and tin-plated aluminum connectors to
replace three mechanical load lugs. UL listed as used on the
load side (OFF) end.

Terminal Shields
The terminal shield is available for line terminal areas in
3- and 4-pole circuit breakers. Special terminal shields
are also available for use when an electrical (solenoid)
operator is mounted on the circuit breaker. The standard
style number by pole for each terminal shield is for a
package of 10 and is priced per each package. Special
terminal shields are packaged individually.
