cannot have an internal breaker. The external battery breaker is a crucial part of
the external battery cabinet or rack and must be placed in it.
Both internal and external battery breakers can be tripped (switched off) by
energizing its shunt trip coil. The shunt trip coils are energized (controlled)
through connectors X5 and X6. The status signal of the external battery breaker
is connected to the Signal Inputs connector. There are five signal inputs and the
user may utilize any one of them; the recommended input is number five. Status
contacts of the Eaton battery breakers are open if the breaker itself is open. The
default voltage of the shunt trip coil is 24 Vdc. For 48Vdc shunt trip, contact local
Eaton Service Engineer.
Note: The default voltage of the battery breaker shunt trip coil is 24Vdc. For a
48Vdc shunt trip, contact an authorized Eaton Customer Service Engineer.
