Download the free Schneider Electric’s Power Device mobile app – available on both Android and iOS free of charge, you can get connected to MasterPact MTZ Air Circuit Breaker from your smartphone via Bluetooth, NFC or USB cable.

Optimised Safety

Highly resistant to environmental stresses, MasterPact MTZ Air Circuit Breaker protects your electrical system regardless of changes in the external environment, hence maximising power uptime and safety.

Remote Control and Monitoring on Mobile Device

MasterPact MTZ Air Circuit Breaker allows wireless remote control of the circuit breaker via Bluetooth LE, keeping maintenance staff outside of the arc flash zone during operation. With the MasterPact MTZ Air Circuit Breaker mobile app, you can keep track of the health status of your air circuit breaker, allowing proactive maintenance before asset failure.

Trip Cause Identification and Reset

Along with Bluetooth, Near Field Communication (NFC) is included, allowing your smartphone to monitor MasterPact MTZ Air Circuit Breaker’s condition under any circumstances. The air circuit breaker captures waveform data during tripping events and can be accessed even without power. The mobile app provides instantly the trip cause (e.g. earth leakage, overload, short circuit, etc.) and step-by-step breaker reclosing instructions to re-energise your system, enabling minimal downtime and power restore quickly and safely.

Timely Warnings and Alerts

Very often, you may not be aware of your air circuit breaker’s deteriorating health condition, or that your air circuit breaker is reaching its maximum load capacity. MasterPact MTZ Air Circuit Breaker’s mobile app alerts you when your air circuit breaker is tripped, its remaining service life falls below a threshold level or many other critical instances. These alerts enable you to take corrective or preventive actions in a timely manner.

Integrated Monitoring for Energy Efficiency

MasterPact MTZ Air Circuit Breaker is the first air circuit breaker to embed accurate Class1 power meter, compliant and certified with IEC 61557-12. Energy efficiency is achieved by accurate energy usage analysis, optimisation, cost allocation and assessment of energy usage trends. By connecting to an advanced software providing real-time energy consumption monitoring, control and reporting, you can access your energy usage, energy cost breakdown and power quality events on a single dashboard. This data helps you identify potential energy savings and schedule corrective, preventive or predictive maintenance for your electrical system to maximise both energy and operational efficiency.

Integration with Building Management System

Circuit-level data is useful for energy control and management of your electrical system. MasterPact MTZ Air Circuit Breaker offers seamless integration with building management systems (BMS) using native embedded Ethernet connection. Instant and comprehensive views of your building power consumption provide useful input for building-level energy measurement, management and network analysis.
