Connecting MasterPacT MTZ Circuit Breakers to the ULP System

Introduction

Use the RJ45 plug/plug ULP cord to connect a MasterPacT MTZ circuit breaker to the ULP system. The circuit breaker must have a ULP port module.

ULP Port Module

Depending on the type of circuit breaker, the ULP port module is supplied as follows:

• As standard on MasterPacT MTZ2/MTZ3 drawout circuit breakers.

• As an option on MasterPacT MTZ1/MTZ2/MTZ3 fixed circuit breakers and MasterPacT MTZ1 drawout circuit breakers. It is mounted with the terminal blocks of the circuit breaker.

The ULP port module:

• Supplies power to the MicroLogic X control unit.

• Has an integrated ULP line termination.

• Enables the connection to external ULP modules, like the IO module or the IFE interface.

For MasterPacT MTZ drawout circuit breakers with optional EIFE interface, the ULP port module:

• Supplies power to the EIFE interface.

• Connects the EIFE interface to the other IMU modules (for example, IO module).

Power Supply of ULP Port Module in MasterPacT MTZ Circuit Breakers

The ULP port module in MasterPacT MTZ circuit breakers supply power directly to the MicroLogic X control unit and EIFE interface.

EIFE Embedded Ethernet Interface for One MasterPacT MTZ Drawout Circuit Breaker

The EIFE interface is an optional accessory that is mounted on the cradle of a MasterPacT MTZ drawout circuit breaker.

The EIFE interface enables MasterPacT MTZ drawout circuit breakers to be connected to an Ethernet network. It provides digital access to all the data delivered by the MicroLogic X control unit. In addition, it monitors the position of the device in the cradle: connected, test, and disconnected.

Kits with cord between ULP port module and EIFE interface in different lengths are available.
