1 PRODUCT DESCRIPTION
This section describes the functions and features provided by the PowerWorx Select Series
circuit breaker panel and provides a table of product specifications.
1.1 Product Functions and Features
The Select Series circuit breaker panel, shown on the cover of this manual, supplies protected
dc power to the –24 Vdc and –48 Vdc powered equipment typically installed in a central office,
multimedia headend, remote site, CEV, or other restricted access location. The panel provides
the following basic functions and features:
• Self-configuring voltage (–24 Vdc or –48 Vdc) capability to simplify installation and
allow one panel to fit most dc voltage applications.
• Ampere ratings and ON/OFF designations clearly marked on each circuit breaker.
• Eight single-pole circuit breaker mounting positions (two-pole breakers require two
mounting positions) per bus.
• Two sets of mounting brackets to permit panel installation in a 19- or 23-inch, WECO or
EIA, equipment rack.
• Mounts within 1 rack space (1.75 inches).
• Dual-bus power feeds with a maximum input rating of 100 Amps per bus.
• Two-hole compression-lug style terminals for input power connections. Screw-down
barrier terminal strips for output power connections.
• Screw-down or wire-wrap pin terminals (option) for alarm connections. A tripped breaker
or loss of power initiates relay operation which opens one set of relay contacts (form C)
and closes another set. The alarm contacts may be used to open or close a loop connected
to an external alarm system.
• Two field-replaceable high-brilliance power indicators (green LED’s) and two non-
replaceable high brilliance alarm indicators (red LED’s).
• Two grounding studs to ensure reliable ground connectivity.
• Easy to remove/replace plastic protective covers mount over the input and output terminal
connections to enhance safety.
1.2 Circuit Breaker Panel Components
The panel consists of the components shown in Figure 1 . Panel components are either mounted
on or housed within a putty white powder-painted sheet metal enclosure. The circuit breakers,
the power LED indicators, and the breaker alarm LED indicators are mounted on the front side
of the enclosure. Unused circuit breaker mounting positions are covered with blanks.
Replacement circuit breakers, lug terminals, a cable management bar, and other items are
available separately as accessory items.
Warning: Use of one bus only on a dual bus panel will result in false alarms for the unused
bus. Power is required on both buses on a dual bus panel for normal operation.
