Air Circuit Breakers ME10

Reference guide - October 2014

Series ME10

The new serie ME10 has been designed as a Modern ‘Power

Circuit Breaker’ without neglecting its AEG’s heritage of more

than 50 years in building Air Circuit Breakers.

The ME10 range of Power Circuit breakers encompasses a line

of 3 and 4 pole Air Circuit Breakers with Nominal Currents ranging

from 400 to 6400Amp in four basic envelopes. (see diagram).

One of the most important user parameters is not the nominal

rating of an ‘Air Circuit Breaker’ in free air but its current Rating

within a panel or enclosure.

Breakers ‘enclosed ratings’ are determined by the heat dissipation

produced by the device and its ability to carry current at the

temperature within the enclosure.

ME10 Power Circuit breakers have been designed with low

Power dissipation values and allow relatively high currents at

high ambient temperatures.

The serie ME10 has been designed to offer an uncompromising combination of a fast

interruption at high fault levels attaining values of 40 Milliseconds or less whilst maintaining

selectivity. The electronic trip unit, already in its basic model, is equipped with protection

channels for overload and short-circuit with delay adjustment intervention, in a wide range

of bands of time

Optionally a full network measurement device can be installed on the device. Relays can

be included to trip the breaker on Voltage Unbalance, Current Unbalance, Power reversal

etc. The device can be equipped with

Communication for use with the Modbus

or Profibus protocol whilst events as

Overload, Short-circuit and Groundfaults

can be tracked, the RELT function to

protect Service Personnel against the

hazards of Short Circuits.

Independent of the number of poles,

rated current or interruption rating, each of the two patterns has a

common height, depth and cut-out dimension.

This strongly simplifying the design of panels and equipment in

which these devices are used.

The basic breaker width has been optimized to allow for space

to connect in- and outgoing bus bars and cables. Both Fixed

and Draw-out Power Circuit Breaker types are supplied with rear

connections suitable for Rear Access Horizontal busbar connection.

A large range of internal accessories as Electrical Operators, up to four Shunt

Releases, Closing Coils or Undervoltage releases, Interlock Coils, Auxiliary and

Alarm contacts, Carriage switches, Coil indication contacts and Breaker status

switches are available.
