These distribution panels accommodate up to 10 or 20 circuit breakers (depending on model) within a compact rack-mount housing, occupying only 2 RU of rack space. The circuit breakers feature a unique plug-in design which requires only front access for quick, easy installation during initial power system configuration, as well as future system expansion. Features Model DST-20A (UL) features dual
isolated 10 circuit A and B buses, each rated at 450 amps, enabling redundant
power configuration or different voltages/ground references. A and B inputs can
also be paralleled, creating a single900 amp bus. Model DST-10 (UL) has a single
450 amp bus which accepts up to 10 breakers. Input/output wiring is rear access via
bus bars that accept single or double hole lugs. Input/output buses are secured
to the load breaker sockets via solid nickel-plated copper bus material.
