Terminals
Breakers include load terminals only➌➍.
Terminals are Underwriters’ Laboratories,
Inc. listed as suitable for wire type and
size. When used with aluminum conductors,
use joint compound. When line
terminals are required, order by style
number from table at no charge with the
breaker.
Style 624B100G02
Insert collar enclosing
conductor as shown.
Locate nut on top of
conductor and tighten
securely with screw and
washer. Caution: Collar
must surround conductor.
Style 624B100G10
Assemble collar on
top of conductor as
shown. Tighten securely
with screw and washer.
LFB Current Limiter Attachment➐
The LFB Current Limiter is an attachment
that bolts to the load end of a standard FB
thermal magnetic or magnetic only breaker,
providing 200,000 Amperes Interrupting
Capacity (AIC) at up to 600 volts AC.
Limiters for thermal magnetic breakers are
listed with Underwriters’ Laboratories, Inc.
Current limiters must be applied as indicated
in the table.
Standard LFB terminals are suitable for
Cu/AI cable. Ratings thru 70 amperes
accept (1) #14-#2, and 100 and 150
amperes accept (1) #1-4/0. ➑

Special Calibrations➏
Special calibration price additions apply to
ampere ratings not listed as standard or
for ambients other than 40°C or 50°C. For
frequencies other than 0-60 Hz AC, refer to
Cutler-Hammer. See Application Data 29-
160 for information regarding special conditions.
Maximum calibration for 400 Hz is
135 amperes.
50°C Calibration➏
Add suffix “V” to catalog number for complete
breaker, listed above, when ordering
breakers to be used in 50°C ambients.
Ambient Compensating Breakers➏
To order, add suffix letter “A” to standard
thermal magnetic breaker catalog number.
Available in all standard ratings of EB,
EHB, FB and HFB breakers up to ratings of
100 amperes. Factory adder 20%.
Federal Specification Classifications
EB, EHB, FB and HFB breakers meet
requirements of Federal Specification
W-C-375b as follows:
EB: 1-pole, Class 11a; 2-, 3-poles, Classes
10b, 11b, 12b
EHB: 1-pole, Class 13a; 2-, 3-poles,
