Schneider Electric redefines power distribution through digitisation

Published: 11-May-2016

Company introduces MasterPact MTZ next-generation low-voltage breaker with industry-first embedded Class 1 metering

As the global specialist in energy management and automation, Schneider Electric has been the benchmark for air circuit breakers (ACB) in electrical distribution for three decades - first with the Masterpact M, followed by the Masterpact NT/NW.

The company announced the introduction of the Masterpact MTZ, the next generation of high-power low-voltage circuit breakers, combining the company’s legendary performance and reliability with new digital capabilities.

Key customer benefits of the Masterpact MTZ include:

  • A new industry first with embedded Class 1 metering, saving project time and energy usage
  • Improved mechanical and electrical performance, even in harsh environments
  • Ability to monitor and control circuit breaker safely with a smart phone as main human machine interface (HMI), even in power outage
  • Stay notified of any event and prevent overloads through real-time remote monitoring capabilities
  • Ability to customise circuit breaker with digital modules for ultra flexibility and operational efficiency without downtime
  • Integrate Masterpact seamlessly in smart panels thanks to the embedded ethernet connection
  • Same footprint allowing easier upgrades and replacements without any need for re-certification

“We are redefining power distribution in this new world of energy we live in today and our future-ready Masterpact MTZ is great proof point of this,” said Philippe Delorme, executive vice president for the building & IT business at Schneider Electric.

“Customers expect power distribution to be safer, more-reliable, efficient, sustainable and securely connected. The new Masterpact’s connectivity, digital capabilities and ability to be seamlessly integrated into our EcoStruxure architecture will deliver significant benefits for end users, specifiers, panelbuilders and contractors requiring high power breakers as part of low-voltage solutions for industrial sites, critical applications and buildings.”

More performance

Masterpact MTZ is the first air circuit breaker to embed accurate Class1 power meter, compliant and certified with IEC 61557-12. Energy efficiency is achieved thanks to accurate energy usage analysis, optimisation, cost allocation, and assessment of energy usage trends. Energy management is compliant with international regulations ISO 50001 and IEC 60364-8.

Easier upgrades

Building on its strengths, the Masterpact MTZ will offer the same ratings, the same tripping performance and the same footprint for seamless, quick integration and retrofitting in switchboards as the current Masterpact range. This seamless transition from Masterpact NT/NW to Masterpact MTZ means no switchboard redesign required and no need to run switchboard recertification tests as per IEC 61439-2. In addition, the product offers easy integration in Smart Panels and connection to management systems with native embedded Ethernet connection.

More reliability

Masterpact MTZ protects equipment and activity against cable overloads, short circuits and insulation faults. It offers outstanding power uptime demanded by low-voltage electrical distribution networks, even in the harshest environments. Masterpact MTZ also offers excellent mechanical and electrical performance, going beyond standards and withstanding the highest levels in voltage fluctuations, electromagnetic disturbances, vibrations, shocks, corrosive and chemical ambience and severe temperatures.

More flexibility

Customising Masterpact MTZ with digital modules can also be achieved anytime, anywhere. Various advanced function options are available with digital modules for protection, measurement, diagnostics and maintenance. The Masterpact MTZ is scalable at any stage of the lifecycle, from design and configuration to commissioning (for last-minute changes) and operation upgrades, without power interruption or protection shutdowns.

More safety

Achieving safe and efficient day-to-day facility management is easier through connectivity to smart phones and operations and analytic software. The interactive smart HMI reduces safety risk for local maintenance as no direct contact is required for quick analysis and action through a secure bluetooth connection. Quick view, self-diagnosis of protection setting and modification, energy consumption, power quality, phase balance, and health status are all available real time. In addition, for remote notifications, the Facility Hero digital maintenance and collaborative logbook allows proactive maintenance and ensures secure continuity of operation, periodic inspection, warnings and alarms.

More uptime

In case of power outage, customers can minimise downtime and restore power quickly and safely using their smart phone. Key data is saved before tripping (measures, protection settings) and even without power, thanks to an NFC connection that gives a root cause explanation and step-by-step breaker reclosing and power recovery instructions.

Future ready, more connected and digital

Masterpact MTZ is future ready as it seamlessly integrates within the Smart Panels architecture, and can be remotely monitored and controlled with any supervision system to carry out predictive and preventive maintenance and asset and energy management, thanks to its embedded ethernet connection.


Providing a digital user experience throughout its lifecycle, Masterpact MTZ also offers unprecedented connectivity. This includes:

  • Configure and order using the MyPact digital configurator and ordering tool
  • Build, commission, and conduct factory-acceptance tests through Ecoreach software
  • Maintain and operate real-time using the full potential of PowerStruxure that includes embedded web pages, Facility hero, Facility Insights, Power Monitoring Expert, Power Scada Expert, and seamless integration into SmartStruxure building management
  • Upgrade and customise at any time in the cycle with digital modules
  • Unleashing hidden cost savings

In addition, from planning to installation, operation, maintenance, optimising and renewal, Masterpact MTZ can be managed through Schneider Electric’s Field Services organisation. This expertise, combined with the native connectivity of Masterpact MTZ and Smart Panels, enables conditions-based maintenance, remote facility management, asset management and improved energy management services, providing significant cost savings in energy and maintenance as well as advanced technical support.
