Energy storage circuit breaker in power distribution cabinet

What is a power distribution cabinet?

D Power distribution cabinets of large PDUs are often seen in large data centers for raised and non-raised floor applications to take incoming power and distribute it to an individual rack or groups of racks. Distribution capacity can range from 84 to 252 circuit breaker pole positions.

Do power distribution units run out of breaker poles?

Therefore most Power Distribution Units (PDUs) run out of circuit breaker poles before they run out of rated capacity. The Liebert RDC extends the functionality of the PDU by packaging 168 poles (four complete panelboards) in a stand-alone cabinet with the smallest possible footprint.

What is the purpose of a circuit breaker?

circuit breaker’s purpose is to open a circuit, stop the flow of electricity, and contain high currents created by a fault. Typical situations that require circuit breaker protection include short circuits or ‘islanding’ when utility power is backed up by a generator or renewable energy source.

What is a rack power distribution unit?

Rack power distribution units, also known as rack PDUs, are a key component to any IT environment. As the name suggests, they distribute power to network equipment within racks. A common misconception is that they’re just power strips, and at first glance, they even look like it, but modern rack PDUs provide benefits a simple power strip cannot.

What is a solid-state circuit breaker (sscb)?

This delay causes high fault currents and electrical arcs which wear the breaker contacts. A potentially superior solution is the solid-state circuit breaker (SSCB), which uses power semiconductors to quickly open a circuit with no moving parts subject to wear.

What is a power distribution rack (PDR)?

C Power distribution racks (PDR) are typically seen in larger high-density data center environments. A power distribution rack provides space-saving power distribution in a flexible design. These racks can offer 168 circuits and accommodate more servers with multiple power cords and rack PDUs with growing loads.
