2RU DC Breaker and Fuse Panels
API Technologies’ 7400-D-79 Breaker Interface Panel offers a reliable solution
for power distribution and circuit protection. Power and return lines for all panel
circuits are isolated in the “off” state by magnetic circuit protectors, offering
superior protection and safety. This panel operates at -48VDC with a maximum
current of 70 Amps per side.
The unit is designed with a removeable front panel to provide access to 12
pluggable circuit breakers. A bi-color LED over each input terminal block
provides verification of proper polarity termination at power hook-up. Red
indicates a reverse polarity condition.

-- Circuit breaker protection for
your valuable DC system.
-- Power and return lines are
isolated for all circuits in the
“off” state by magnetic circuit
-- A bi-color LED over each input
terminal block assures correct
polarity during hook up. Red
indicates reverse polarity.
-- Positive polarized latching
connector system provides for
quick field installation.
-- With the removal of the front
access panel, the individual
circuit breakers can easily be
serviced to minimize down time.
-- PDU circuit protection
configuration is easily modified
by the user but not to exceed the
maximum current rating of the
PDU per output.
-- PDU circuitry utilizes bus bar and
PCB “Heavy Trace” technology
for enhanced power dissipation.
