1.1 Product Functions and Features
The Circuit Breaker Panel With Reset Switch supplies low-voltage, protected dc power to –24
Vdc or –48 Vdc powered equipment installed in a central office, multimedia headend, remote
site, or other restricted access location. The panel provides the following functions and features:
• Two side-by-side power buses, designated A and B, each with seven power outputs.
• Fourteen circuit breakers (seven per bus). Each bus has two 10 Amp circuit breakers and
five 5 Amp circuit breakers.
• Maximum input rating of 45 Amps per bus. This corresponds to a maximum input rating
of 90 Amps for the total panel.
• One Power On LED (green) and one Breaker Alarm LED (red) for each bus.
• One Reset switch for the total panel. The Reset switch allows the operator to reset the
panel to a non-alarming state if a breaker has been turned off or tripped due to an
overcurrent condition.
• Alarm contacts (screw-down barrier terminal strips) for remote reporting of an alarm
condition. The alarm contacts can be used to open or close a loop connected to an external
alarm system.
• Mounting brackets providing the ability to mount the panel in a 19-inch (482.6 mm) or 23-
inch (584.2 mm) WECO or EIA equipment rack. The panel occupies one rack space (1.75
inches, 44.4 mm).
• Two-hole compression-lug style terminals for input power connections.
• Screw-down barrier terminal strips for output power connections.
• Two chassis ground studs.
• Easy to remove rear protective covers. These covers mount over the input and output
power connections to prevent inadvertent contact.
1.2 Panel Components
Figure 1 shows the components of the circuit breaker panel.
Note: The panel requires one open rack space above the chassis and one open rack space
below the chassis for heat dissipation.
