DC Power Distribution – Panel with Circuit Breakers and Fuses


DC Power Distribution – Panel Incorporates GMT Fuses and Plug-in Circuit Breakers

DC Distribution Panel – DST-FB offers a unique combination of circuit protection, utilizing both circuit breakers and GMT fuses in a single, 2 RU rack mount assembly. The DST-FB panel provides system integrators with a flexible DC power distribution system allowing the installer to assign low power loads to fuses and high power loads, up to 30 amps, to circuit breaker protected circuits. The DST-FB panel features dual busses, Bus A accommodates 8 plug-in circuit breakers and Bus B up to 8 GMT style fuses. Front panel LEDs indicate power available per bus as well as blown fuse and tripped/off circuit breaker occurrence. Tripped condition also activates form C contacts for integrating remote alarm reporting. The DST-FB panel integrates with 12VDC, 24VDC or 48VDC systems, any ground reference, making the unit ideal for any power system.
