Schneider Electric Masterpact MTZ circuit breakers

The Schneider Electric Masterpact MTZ is a high-power, low-voltage air circuit breaker with certified embedded Class 1 energy metering.    

The Masterpact range includes Masterpact M and NT/NW circuit breakers. The circuit breaker retains essential properties such as footprint, power connection, thermal rating and tripping performance to provide switchboard builders the convenience to use on their existing designs. AS/NZS 61439-1 switchboard type test certificates for NT/NW are also allowed.   

The Masterpact MTZ’s connectivity, digital capabilities and ability to be seamlessly integrated into the EcoStruxure architecture are said to deliver significant benefits for end users, specifiers, switchboard manufacturers and contractors requiring high-power breakers as part of low-voltage solutions for industrial sites, critical applications and buildings.  

The circuit breaker is designed to withstand high-level vibrations in accordance with IEC 60721 (1g @ 2–200 Hz) and is immune to twice the level of radiated disturbance as per the IEC 61000-4 standard.
