Product Description

Structures are compartmentalized and are built with barriers isolating each circuit breaker. The structure has large conduit space within the main and branch circuit breaker sections.

QED-6 switchboards are listed to UL 891. MasterPact and PowerPact circuit breakers are listed to UL 489. A UL label can be affixed where UL coverage exists for all component material, parts, and devices in the section.

Drawout construction allows quick and simple replacement of circuit breaker elements. If an emergency occurs, circuit breakers may be removed from low-priority circuits and re-installed to serve high-priority circuits. MasterPact and PowerPact circuit breakers are easily changed while the remainder of the switchboard is energized.

MasterPact and PowerPact circuit breakers provide disconnecting and overload protection for the circuit it controls. Each is contained in an individual compartment and can be isolated easily from the energized circuit and withdrawn from the compartment for quick inspection, maintenance, or replacement. The entire switchboard or any other feeder circuits need not be shut down during this operation, thus minimizing production downtime.

Optional control power transformers, meters, and other control devices can be mounted in the auxiliary instrument compartments. These compartments are furnished with hinged doors for easy access.

The secondary wiring design allows for front access to circuit breaker control and communications wiring without removing the circuit breaker from its compartment. The vertical wireway is located on the right side of the section for easy access and wiring installation. The horizontal wireway is located directly above the circuit breaker, providing direct access to control and communication terminations.

MasterPact and PowerPact circuit breakers provide clear access to all circuit breaker controls, indicators, and trip unit functionality without opening the compartment door. MasterPact circuit breaker racking is also achieved with the compartment door closed.

The family of MicroLogic electronic and programmable trip units provide you with a choice of expanded information, power quality readings, and communication capabilities on MasterPact circuit breakers. MicroLogic trip units can be integrated into the optional PowerLogic system.

QED-6 switchboards are available with the PowerLogic metering, data acquisition, and control system. The optional system is used in addition to, or in lieu of, the Type A, Type P, and Type H MicroLogic trip units for the MasterPact circuit breaker. PowerLogic functions are included in MicroLogic high-end trip units. Several highly accurate circuit monitors are available to work in conjunction with the PowerLogic System Manager Software to manage and control your electrical distribution system.
