Special Calibrations➋<br />
Special calibration price additions apply to<br />
ampere ratings not listed as standard or<br />
for ambients other than 40°C or 50°C. For<br />
frequencies other than 0-60 Hz AC, refer to<br />
Cutler-Hammer.<br />
50°C Calibration➋<br />
Add suffix “V” to catalog number for complete<br />
breaker when ordering <strong>breakers</strong> to<br />
be used in 50°C ambients. Same price as<br />
standard 40°C <strong>breakers</strong>.<br />
For CSA, see page 41.<br />
Type JB <strong>breakers</strong> meet requirements of<br />
Class 19a <strong>circuit</strong> <strong>breakers</strong> as defined by<br />
Federal Specification W-C-375b.<br />

Terminals➊<br />
Two terminals are required per pole.<br />
Terminals are Underwriters’ Laboratories,<br />
Inc. listed for wire type and range listed<br />
right. When used with aluminum conduc-<br />
➊ Terminals are shipped separately from breaker frame.<br />
➋ Not listed with Underwriters’ Laboratories, Inc.<br />
➌ 2-pole <strong>breakers</strong> are supplied in 3-pole frames with current carrying parts omitted from center pole.<br />
➍ Select desired terminal from table and order as separate item.<br />
➎ Ratings above 10,000 amperes not UL listed.<br />
tors, use joint compound. To order<br />
optional copper only terminals, add suffix<br />
“C” to complete breaker catalog number.<br />
