Grounding/Earthing Device (IEC Only)
All EntelliGuard G circuit breakers can be fitted with a
grounding/earthing device, which has a short circuit rating
equal to the breaker withstand rating. This permits either the
feeder cables or the busbar to be safely grounded and
locked during system maintenance operations (Table 4.36).

Rejection Device
A factory-installed rejection feature prevents mismatching
breakers and cassettes/substructures. This prevents (a)
inserting a breaker with a lower rating into a higher rated
cassette/substructure and (b) inserting a higher rated
breaker into a lower rated cassette/substructure. Mis-
insertion Interlock catalog number is GREPM.
