Power meter inputs
The NSX moulded case circuit breakers up to 630A have current transformer modules that fit directly on to
the load terminals of the breaker. As well as the current transformer coils they also have self protected voltage
connections off each phase. This eliminates the need to have additional overcurrent protection on these circuits.
The meter is wired direct from this CT module without the need for any intermediate devices.
Panelboard configurations
250A Powerboard
There are two versions of this equipment, basic or with the facility to have metering. The meter versions allow
metering to be added to any 3 or 4 pole MCCB fitted in the board. All components are easily fitted; there are no
extension boxes to fit or apertures to cut. The meters are positioned behind the overall lockable door preventing
unauthorised access to the meters. MG25P2M has 4 apertures, MG25P4M has 5.
Note: the meters and CT modules must be ordered separately. The wiring looms to link the CT modules to the
meters are included with the panelboards.
Metering options are not available for the 250A panelboard. It is recommended that a MG6Pxx board is used
with a 250A incomer.

Incoming metering
This is easily added to a board when it is first being installed. The kit comprises an extension box that houses
the meter and, when fitted to the same end of the board as the incomer, provides additional space for the main
incoming cables. All components including the meter, CTs and wiring is included in the kit. The meter is fully set
up for the CT ratio and the voltage configuration.
Outgoing circuit metering
Metering can be fitted to some or all of the three phase outgoing circuits on 630A & 800A boards whether the
boards are fitted with incoming metering or not.
The PowerLogic PM700 series power meter offers all the measurement capabilities required to monitor an electrical
installation in a single 96 x 96 mm unit extending only 50 mm behind the mounting surface. With its large display,
you can monitor all three phases and neutral at the same time. The anti-glare display features large 11 mm high
characters and powerful backlighting for easy reading even in extreme lighting conditions and viewing angles.
The PowerLogic PM700 series meters are available in four versions:
n
PM700, basic metering with THD and min/max readings
n
PM700P, same functions as the PM700, plus two solid-state pulse outputs for energy metering
n
PM710, same functions as the PM700, plus one RS 485 port for Modbus
communication
n
PM750, same functions as the PM710, plus two digital inputs, one digital output and alarms
