Schneider Electric MasterPact MTZ Circuit Breaker Product Features

1. High Current, High Breaking Capacity
The MasterPact MTZ covers multiple frame classes to meet the needs of large industrial and commercial power distribution systems. The IEC series offers a total rated current of approximately 630A–6300A and provides various breaking classes, suitable for critical circuits such as transformer incoming lines, low-voltage main incoming lines, and bus tie lines.

2. MicroLogic X Intelligent Control Unit
Utilizing the advanced MicroLogic X control unit, protection, measurement, diagnostics, and maintenance functions are integrated into a single platform. Depending on the configuration, it can provide protection against long-delay, short-delay, instantaneous, and ground faults, and its functionality can be expanded through digital modules.

3. High-Precision Energy Measurement
Built-in high-precision energy metering function, some configurations support Class 1 active power and energy measurement, enabling real-time monitoring of equipment operation and energy usage, which is beneficial for energy management and fault analysis.

4. Digitalization and Intelligent Communication

MTZ is a key product in Schneider Electric’s digital low-voltage power distribution system, enabling intelligent connectivity, remote monitoring, and wireless maintenance. It can be integrated with Schneider Electric’s EcoStruxure Power system. It supports wireless alarm monitoring, parameter viewing, and maintenance operations via smartphone.

5. Digital Module Expansion
Users can add digital modules to expand the functionality of the MicroLogic X control unit according to actual project needs, without simply relying on hardware replacement to add advanced functions. This makes future upgrades and function customization more flexible.

6. Fixed and Drawout Structures
It is available in both **fixed** and **drawout** structures, with 3P and 4P configurations, facilitating selection for different low-voltage switchgear solutions. The drawout structure is particularly suitable for applications requiring rapid maintenance and replacement, as well as improved power supply continuity.

7. Strong Reliability and Environmental Adaptability
The product is designed for durability in industrial environments, adapting to complex operating environments such as temperature, humidity, vibration, altitude, and electromagnetic interference. Schneider Electric’s data indicates a typical operating temperature range of -25°C to +70°C.

8. A wide range of accessory options: It can be configured with various accessories such as shunt trip units, closing coils, auxiliary contacts, electric energy storage mechanisms, and communication modules, facilitating remote opening and closing, status monitoring, and automated control.
