MT Frame Circuit Breaker

Schneider Electric's Masterpact MT is a smart frame circuit breaker (ACB) for low-voltage power distribution, suitable for AC 50/60Hz, 400/500V systems, with a rated current of 630-6300A, breaking capacity of 50-150kA, 3P/4P configuration, fixed/drawer-type installation, equipped with a Micrologic intelligent control unit, providing four-stage protection and digital monitoring, and suitable for primary/secondary power distribution scenarios such as industrial, commercial and public buildings, and data centers.

PRODUCT DETAIL

Features:

 

Intelligent Protection: The Micrologic control unit provides four-stage protection with selective coordination to reduce the scope of power outages; optional Vigi leakage protection adapts to personal and equipment safety requirements.

 

Breakdown and Current Limiting: High current limiting design (L1/H3 level) quickly cuts off faults, reducing short-circuit energy surges and improving system safety.

 

Digitalization and Connectivity: Supports Modbus, Profibus, and other communication protocols, and connects to the EcoStruxure platform for remote monitoring, fault location, and energy efficiency analysis.

 

Installation and Maintenance: Drawer-type hot-swappable installation facilitates maintenance; modular accessories (auxiliary/alarm contacts, shunt/undervoltage trip) can be added on-site to adapt to control requirements.

 

Safety and Reliability: Clearly defined handle position with lockable breakout state; 8kV surge withstand voltage, electromagnetic interference resistant, adaptable to complex industrial environments.

 

Typical Applications:

 

Industrial Sector: Factory main power supply, low-voltage side of transformers, busbar interconnection, high-capacity motor circuits; H2/H3 rating adaptable to high short-circuit levels.

 

Public and Commercial Buildings & Data Centers: Building main power distribution, UPS front-end, generator paralleling; drawer-type design for easy maintenance; four-stage protection ensures power continuity.

 

Infrastructure: Critical loads such as rail transit, airports, and hospitals; intelligent monitoring and selective protection enhance power reliability.

 

Other Scenarios: Backup power switching, photovoltaic/energy storage combiner; adaptable to DC and special voltage systems (e.g., 1000V AC).
