➊ Terminals are shipped separately from breaker.<br />
➋ Optional terminal.<br />
➌ Ratings above 10,000 amperes not UL listed.<br />
➍ Not listed with Underwriters’ Laboratories, Inc.<br />
➎ If upgrading an LB, HLB breaker to a Series C K frame in a panelboard application, also order TAD3 spacer kit.<br />
Magnetic Only and Ambient Compensating<br />
Breakers➍<br />
For description, refer to Application Data<br />
29-160. To order, select trip unit from table<br />
at left, frame and terminals.<br />
Special Calibrations➍<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 <strong>circuit</strong>s,<br />
refer to Cutler-Hammer. See Application<br />
Data 29-160 for information regarding<br />
special conditions. Maximum calibration<br />
for 400 Hz is 300 amperes.<br />
50°C Calibration➍<br />
Add suffix “V” to catalog number for complete<br />
breaker or trip unit only, when ordering<br />
<strong>breakers</strong> to be used in 50°C ambients.<br />
