MasterPact MTZ2/MTZ3 Normal Operation

Device Indication Contacts

The position of the device main contacts is indicated by OF indication contacts.

Anti-Pumping Function

MasterPact MTZ devices provide a mechanical anti-pumping function. In the event of simultaneous maintained opening and closing orders, the standard mechanism blocks the main contacts in the open position. After a trip due to an electrical fault or intentional opening using the manual or electrical controls, the closing order must first be discontinued, then reactivated to close the circuit breaker. This prevents a cycle of closing and opening.

When remote operation features are used, allow at least four seconds for the MCH gear motor to charge the device closing spring completely before the XF closing voltage release is actuated.

To prevent the device from closing prematurely, the PF ready-to-close contact can be series connected with the XF closing voltage release.

Two control modes are available: Manual and Auto.

Manual control mode only accepts orders made using one of the following:

 The mechanical buttons on the front of the circuit breaker.  The external pushbutton connected to the MN/MX/XF voltage releases.  The BPFE electrical closing pushbutton.

Auto control mode has two settings: Local or Remote. All orders accepted in Manual control mode are accepted in Auto control mode, as well as orders from local or remote communication as follows:

 Auto Local: the operator needs to be close to the circuit breaker to establish communication and only

orders sent from a local source through communication are accepted:

 EcoStruxure Power Commission software through USB connection  EcoStruxure Power Device app with MasterPact Operation Assistant Digital Module through

Bluetooth or USB OTG connection

 Auto Remote: the operator does not need to be next to the circuit breaker to establish communication

and orders are accepted only when sent from a remote source through the communication network.

NOTE: EcoStruxure Power Commission software connected through the communication network can be used to send control orders to the circuit breaker.

The control mode factory setting is Auto Remote.

NOTE: The switch-disconnector control mode corresponds to the Manual control mode of circuit breakers. To operate a switch-disconnector through communication, it is possible to use an IO module. Refer to
