Pow-R-Command 750 System
LCD Display and Keypad
The Pow-R-Command 750 system provides easy and efficient control
of electrical loads while maintaining a compact design that mounts in
a panelboard enclosure. With one Pow-R-Command 750 controller,
you have the capability of connecting up to three Pow-R-Command
Expansion Panelboards on its own stand-alone subnetwork. This
gives you the ability to have control of 168 breakers with one master
panelboard. The Pow-R-Command 750 is a premier product in the
lighting control industry.
The Pow-R-Command 750 LCD display and keypad features a menudriven interface for complete, quick and easy setup. With this device,
you will be able to configure the entire Pow-R-Command 750 system.
This makes setting up your lighting automation system seamless,
efficient and straightforward. In addition to configuration, you will
have the ability to monitor the status and have full control over the
Pow-R-Command 750 system, including the ability to execute commands. This addition to the panelboard gets you up and running faster
so you can start saving energy today!
Note: Subnetwork can be configured with up to eight BCBs in any
combination making up the 168 breakers. Example: eight panels,
one BCB per panel controlling 21 breakers per panel.
Applications for Pow-R-Command 750 System
The Pow-R-Command 750 system is primarily designed for small to
medium applications, such as, but not limited to: office buildings,
shopping centers, restaurants, schools, parking structures, retail
buildings and multi-site facilities. It provides an easy manner to efficiently control electrical loads while maintaining a compact design. In
addition, the Pow-R-Command 750 offers 16 dry-contact inputs that
can be leveraged with many different types of controls and systems,
such as: security systems, fire/emergency systems, photocell and
switch controls.
The Need for Pow-R-Command 750 Lighting Control
In businesses of all types, there are numerous variables that significantly influence profitability. Among these variables are: electrical
consumption, construction time and the ease with which employees
use the facility. Eaton’s Cutler-Hammer Pow-R-Command
750 system can have a positive impact on all of these elements.
Secure Stand-Alone Subnetwork
With each Pow-R-Command 750 panelboard, you have the ability to
create a stand-alone subnetwork with up to three Pow-R-Command
Expansion Panelboards (totaling eight breaker control buses). Like the
Pow-R-Command 750, each expansion panelboard can house up to
42 Smart Breakers. Such a capability allows a single Pow-RCommand 750 controller to directly operate up to 168 GHQRSP and
BABRSP controllable circuit breakers, with individual control and
status feedback of each Smart Breaker.

Reduced Construction Time and Space
In each Pow-R-Command 750 panelboard are revolutionary devices
known as Smart Breakers. Eaton’s Smart Breaker combines the
interrupting ability of a standard branch circuit breaker with a
remote switching ability. Any combination of Smart and standardbranch circuit breakers can be used in a given panelboard. Because
no additional structures are needed to mount the Smart Breaker,
the extra material and labor from the contactor or relay cabinets
are eliminated.
Lighting Control With No Additional Structures
The Pow-R-Command 750 controller and associated Smart Breakers
mount directly into a standard Cutler-Hammer brand panelboard.
Such panelboards would be required in a facility even if no lighting
control is installed. As a result of this, the Pow-R-Command 750
system and all of its abilities can be installed in the same structures
that would normally be required.
Lighting Control With No Additional Labor
When using contactors or relays to control lighting, there are four
basic elements that need to be integrated into a circuit. This includes
a standard branch circuit breaker mounted in a panelboard, a relay or
contactor mounted in a separate cabinet, a controller mounted in a
cabinet, and the lighting loads. On the job site, the contractor would
need to install pipe and wire from the controller and branch circuit
breaker to the contactor or relay and then to the lighting load. Since
the controller, branch device and remote-controlled switching device
are all located in one Pow-R-Command 750 structure, the contractor
only needs to pipe and wire from the Pow-R-Command 750 panelboard to the lighting load.
