Selecting MasterPacT MTZ2 Circuit Breakers

Operating Conditions

MasterPacT MTZ devices are designed for specified operating conditions in terms of temperature, humidity, vibration, altitude, corrosion, and electromagnetic disturbances.

Beyond the limits defined here, the circuit breakers suffer accelerated aging that may rapidly result in equipment breakdowns.

Refer to the MasterPacT Maintenance Guide for additional information and consult Schneider Electric to confirm mechanical and electrical performances in severe conditions.

Examples of applications with severe operating conditions:

wind turbines
power frequency converters installed in the same electrical equipment or close to the MasterPacT circuit breaker
emergency generators
high vibration marine applications such as thrusters and anchor positioning systems

Safety of Operations

The front face of the MasterPacT MTZ device provides reinforced insulation (Class 2) according to IEC 60664-1. It allows Class 2 installation with circuit breaker control from outside.

Ambient Temperature

MasterPacT MTZ devices are designed to operate in ambient temperature between -25°C (-13°F) and +70°C (+158°F), providing that the temperature around the circuit breaker inside the enclosure does not exceed +70°C (+158°F). If this condition cannot be fulfilled, dedicated measures such as HVAC must be taken.

MasterPacT MTZ devices have successfully passed the tests defined by the following standards for extreme atmospheric conditions:

Dry cold at -40°C (-40°F) (IEC 60068-2-1)
Dry heat at +85°C (+185°F) (IEC 60068-2-2)
Damp heat (temperature +55°C (+131°F), relative humidity 95%)
(IEC 60068-2-30)

MasterPacT MTZ Electrical Equipment Installation Rules

MasterPacT MTZ Device Installation

MasterPacT MTZ devices can be supplied either from the top or from the bottom without degrading performance, in order to facilitate connection when installed in electrical equipment.

Mounting the Circuit Breaker

The weight of the device must be distributed uniformly over a rigid mounting surface such as rails or a base plate.

This mounting plane must be perfectly flat (tolerance on support flatness:
2 mm [0.08 in.]).

Mounting the circuit breaker to a mounting plate that does not meet the flatness requirements could interfere with the correct operation of the circuit breaker.

MasterPacT MTZ devices can also be mounted on a vertical plane using special brackets.


Mounting on Rails		Mounting with Vertical Brackets

MasterPacT MTZ Position in Electrical Equipment

Only one position is authorized.

Electrical Equipment Partitions for MasterPacT MTZ Devices

Sufficient openings must be provided in partitions to maintain good air circulation around the circuit breaker. Any partition between upstream and downstream connections of the device must be made of non-magnetic material.

For high currents, 2500 A and above, the metal supports or barriers in the immediate vicinity of a conductor must be made of non-magnetic material [1].

Metal barriers [2] through which a conductor passes must not form a magnetic loop.

[1] Non-magnetic material

[2] Metal barriers

MasterPacT MTZ Electrical Equipment Busbars

Creating a magnetic loop around a conductor, (via the busbar support for example), must be strictly avoided.

To avoid this:

Either the busbar supports (A) and/or their mounting screws (B) must be made of non-magnetic materials.
Maintain minimum distances for control wires (C) and busbar (D).

A) Busbar supports

B) Busbar support screws

Door Interlock

Door Interlock (VPEC)

Mounted on the right or left-hand side of the cradle, this device inhibits opening of the cubicle door when the circuit breaker is in “connected” or “test” position.

If the circuit breaker is put in the “connected” position with the door open, the door may be closed without having to disconnect the circuit breaker.

Power Connection

MasterPacT MTZ Electrical Equipment Cable Connections

If cables are used for the power connections, their weight must not be applied to the circuit breaker power terminals, but must be supported by the panel structure.

For this, make the connections as follows:

Extend the device terminals using short bars designed and installed according to the recommendations for bar-type power connections (see figure below):
- For a single cable, use solution [1].
- For a multiple cables, use solution [2].
In all cases, follow the general rules for connections to busbars:
- Position the cable lugs before inserting the bolts
  .
- Firmly secure the cables to the framework [3].

Busbar Connections

Install with a maximum distance A between busbar to circuit breaker connection and the first busbar support or spacer with respect to the value of the prospective short-circuit current.

The busbars must be suitably adjusted so that the connection points are positioned on the power terminals before the bolts [4] are inserted.
The busbars weight must be supported by the busbar supports [5] that are solidly fixed to the electrical equipment framework and not by the circuit breaker power terminals.

Electrodynamic Stresses

The first busbar support must be situated within the maximum distance (A) from the power terminal of the circuit breaker. This distance is required so that the busbar can withstand the electrodynamic stresses between phases in the event of a short circuit. The table below gives the maximum distance (A) according to the prospective short-circuit current Isc.

Maximum Distance (A) Based on Prospective Short Circuit Current


Maximum Distance A
Short Circuit Current (kA)	Maximum Distance A mm (in.)
30	350 (13.8)
50	300 (11.8)
65	250 (9.84)
80	150 (5.91)
100	150 (5.91)

Temperature Derating

The current rating of a high-ampere circuit breaker is highly dependent on the actual conditions of installation and connection. Thus it is not possible to give strict values of current rating without performing a temperature rise test in the actual electrical equipment configuration.

MasterPacT MTZ Circuit Breaker Electrical Diagrams

MasterPacT MTZ1 Fixed and Drawout Devices

The diagram is shown with circuits de-energized, all devices open, connected and charged and relays in normal position.

Power*	Control Unit	Indication Contacts

NOTE: It is possible to add a second MX/MX diag&com or a MN/MN diag voltage release. The second MX diag&com voltage release can only be installed after the delivery of the circuit breaker. This is an after-sales adaptation.

Remote Operation*

NOTE: Maximum length of the two wires between A2–A3,/C20C3/C12/C13: 5 m (16 ft.). For the maximum length of the wiring between the AC/DC power supply and the voltage release terminals A1–A3/C1–C3/C11–C13/D1–D2: see Shunt Close (XF), Shunt Trip (MX), and Undervoltage Release (MN) with Basic Coils.
