GE Industrial Solutions Cable Operator Mechanisms for Thermal-Magnetic E150 and Spectra SE150, SF250, and SG600 MCCBs - Manual (Page 2)

Table 2. Circuit Breaker Mounting-Zone Dimensions
To determine maximum mounting dimensions for 60-
inch through 120-inch-long operating cables, add the
respective additional lengths to the 48-inch cable
maximum dimensions. (For example, add 12 inches to E,
F, and G dimensions for 60-inch cable length.)
Maximum Dimensions in Inches
Enclosure 36” Cable 48” Cable
Depth E* F G E* F G
8 13.5 4.0 15.0 25.5 16.0 27.0
10 13.0 5.0 14.8 25.0 17.0 26.8
12 12.8 6.0 14.5 24.8 17.0 26.5
16 10.5 4.5 14.2 22.5 16.5 26.2
18 8.5 3.5 12.6 20.5 15.5 24.6
20 — 0.5 10.0 22.0 15.0 24.0
24 — — — 19.5 14.0 22.0
* Maximum E dimension only if F = 4.5”.
When cable is installed, the minimum cable bend radius
should not be less than 3 inches. The minimum cable
bending requirement must be met to ensure a safe
operating environment.
