2.3 MPX BRM

™

—Branch Receptacle Module (Power Output)

The MPX BRM provides output power distribution to user load equipment. All MPX BRMs include

output receptacles (NEMA, Schuko or IEC) that are overload-protected by 100% rated hydraulic-

magnetic circuit breakers.

MPX BRMs are hot-swappable to allow user installation without powering down the Liebert MPX. Up

to three standard sized (266mm) MPX BRMs can be deployed on a Liebert MPX utilizing the MPX

PRC (Power Rail Chassis) for typical 23U racks and up to six standard size MPX BRMs (Branch

Receptacle Modules) for units utilizing the 1880mm MPX PRC

™

for typical 42U racks. All MPX BRMs

include an alphanumeric LED indicator that uniquely identifies the individual module.

North American and European models of the MPX BRM are available in the following versions and

features:

• Elementary version provides power distribution only. Power metering and alarming are not

supported.

• Branch Monitoring version of the MPX BRM provides power distribution and branch power

metering, including voltage, current, kW, kVA, kW-h and power factor.

• Receptacle Management version of the MPX BRM provides the same features as the Branch

Monitoring models, plus power metering, including crest factor, On/Off control, current alarming,

and operational status of individual receptacles. The receptacles may either be turned On or Off

remotely or programmed for automatic power-on sequencing.

Other important features include:

• An alphanumeric indicator to provide module identification and operational status (not

Elementary models) of the branch current condition. Additionally, the Branch Monitoring version

provides current alarming and operational status of the branch. The unit displays an “o” for an

overcurrent condition and a “u” for an undercurrent condition.

• For Receptacle Management versions, a visual indicator per receptacle alerts the user to the

current condition of the load (not Elementary models).

• The circuit breaker may be opened with the use of a tool. Open circuit breaker detection causes

the alphanumeric indicator to flash (not Elementary models).

• Voltage phasing is determined by the power blade configuration on the bottom of each MPX

BRM

™

, and is clearly marked on the color coded label.

• IEC C13 receptacle types are provided with retaining clips to provide strain relief for the load's

power supply cord.
