Circuit Breaker Panel
Up to two circuit breaker panels may be installed in a Model S00 rack to distribute
-48 V DC power. Each circuit breaker panel provides 8 circuit breakers that protect
each drawer in the rack from excess current and function as DC power switches for
switching off power to the devices and drawers within a rack before servicing. Like
the power distribution panel, each circuit breaker panel may be connected to one or
two customer power sources.
Two standard circuit breaker panels are available with the Model S00 rack. One
circuit breaker panel contains 8 - 15A circuit breakers. The other circuit breaker
panel contains four 20A and four 10A circuit breakers.
The circuit breaker switch is on when it is in the up position, and the switch is off
when it is in the down position.
