COM Option in MasterPacT Circuit Breakers

All MasterPacT devices can be fitted with the communication function thanks to the COM option. MasterPacT uses the Ethernet or Modbus communications protocol for full compatibility with the supervision management systems.

For fixed and drawout devices, the common communication option is made up of:

A BCM ULP module, installed behind the MicroLogic trip unit and supplied with a set of switches (OF, SDE, PF and CH switches), a kit for connection to shunt close (XF) and shunt trip (MX1) communicating voltage releases, and a COM terminal block (inputs E1 to E6).

This module is independent of the trip unit and receives and transmits information on the communication network. An infra-red link transmits data between the trip unit and the communication module.

Consumption: 30 mA, 24 V.

and

The IFM module, the Modbus interface for connection to the network, contains the Modbus address (1 to 99) declared by the user using the two dials in front. It automatically adapts (baud rate, parity) to the Modbus network in which it is installed.

or

The IFE module, the Ethernet interface for low-voltage circuit breakers, enables an intelligent modular unit (IMU) such as a MasterPacT NT/NW or PowerPact circuit breaker to be connected to an Ethernet network. Each circuit breaker has its own IFE and a corresponding IP address.

For drawout devices the Cradle Management option must be added:

The I/O (Input/Output) application module for low-voltage circuit breakers is delivered with the drawout devices ordered with the COM option for cradle management. It must be installed on a steel DIN rail that is properly grounded near the device. The I/O module must be connected to the ULP system and to the cradle position contacts (CD, CT, CE) that transmit the position of the circuit breaker in the cradle.

For communicating remote control, shunt close (XF) and shunt trip (MX1) communicating voltage releases must be added:

The shunt close (XF) and shunt trip (MX1) communicating voltage releases are equipped for connection to the communication module.

The remote-tripping function shunt trip (MX2) and undervoltage release (MN) are independent of the communication option. They are not equipped for connection to the communication module.
