Eaton’s Cutler-Hammer mining service circuit breakers provide
short circuit protection as specified in the code of Federal Reg-
ulations 30 CFR 75.601-2. E
600 ampere L frame electronic trip units feature specifically
designed instantaneous pickup settings to conform exactly
with the code of Federal Regulations 30 CFR 75.601-2. Electro-
mechanical trip units are also available with a wide range of
magnetic pickup ranges.
Table 12-334 lists the conductor size maximum allowable
circuit breaker instantaneous setting and the E
that meets that setting.
