As a factory-new unit originating from Schneider Electric's production facilities in France and India, the MTZ2-40 H1 carries full manufacturer authenticity and the legendary reliability that has made the Masterpact name the global benchmark in low-voltage power circuit breakers since 1989.

Whether you are upgrading an existing Masterpact MTZ installation or engineering a new switchboard for a power generation facility, the MTZ2-40 H1 with Micrologic 6.0X delivers the precision protection, real-time energy monitoring, and predictive maintenance capabilities that modern smart grids demand.

Product Overview: Schneider Electric MTZ2-40 H1 with Micrologic 6.0X

The Schneider Electric MTZ2-40 H1 is part of the groundbreaking Masterpact MTZ range, the world's first truly digitized air circuit breaker platform. Introduced as the evolutionary successor to the industry-dominant Masterpact NT/NW series, the MTZ generation embeds native connectivity, advanced metering, and modular protection architectures directly into the breaker's DNA.

The "MTZ2" designation identifies this unit as a size 2 frame breaker within the MTZ family, optimized for continuous current ratings from 800A to 4000A. The "40" suffix specifies its 4000A rated operational current, making it suitable for main incoming feeders, large motor protection circuits, and bus coupler applications in low-voltage switchboards up to 1000V AC. The "H1" breaking performance classification certifies an exceptional 66kA short-circuit breaking capacity across all standard operating voltages  a figure that exceeds the requirements of most industrial and marine power distribution networks.

At the heart of this breaker lies the Micrologic 6.0X control unit, Schneider Electric's most advanced electronic trip system for the MTZ platform. Unlike conventional analog trip units, the Micrologic 6.0X integrates true energy metering (Class 0.5S accuracy), power quality analysis, communication gateway functions, and predictive maintenance diagnostics in a single modular package. It supports Modbus, BACnet, IEC 61850, and Ethernet/IP protocols natively, enabling seamless integration into Building Management Systems (BMS), Supervisory Control and Data Acquisition (SCADA) platforms, and Schneider Electric's own EcoStruxure Power architecture.

The 4-pole drawout configuration provides maximum installation flexibility. Four poles allow simultaneous isolation of all phase conductors plus the neutral, a requirement in many marine, offshore, and data center applications where neutral continuity must be broken for maintenance safety. The drawout chassis enables the breaker to be racked out to test, disconnect, or removed positions without de-energizing the entire switchboard  a critical operational advantage in facilities where downtime can cost thousands of dollars per minute.

Key Features & Benefits of the MTZ2-40 H1

• Micrologic 6.0X Digital Trip Unit – The most advanced protection and measurement engine in the Masterpact family. Delivers Class 0.5S energy metering, power quality analysis (THD, power factor, harmonic content), and full communication integration without external meters or transducers.
• 66kA Universal Breaking Capacity – The H1 performance level provides 66kA short-circuit withstand at all standard voltages (380V, 415V, 440V, 480V, 500V, 690V, and up to 1000V). This universal rating simplifies specification, reduces spare parts inventory, and future-proofs installations against capacity upgrades.
• 4-Pole Drawout Design – Four-pole switching isolates all active conductors including neutral, meeting marine classification society requirements (DNV, Lloyd's, ABS) and data center grounding standards. The drawout mechanism provides test, disconnected, and removed positions for safe maintenance workflows.
• Native Smart Grid Connectivity – Built-in dual Ethernet ports, Modbus TCP/IP, BACnet/IP, IEC 61850, and EcoStruxure Power Device compatibility enable real-time remote monitoring, predictive diagnostics, and integration with cloud-based energy management platforms.
• IEC 60947-2 Category B Certification – Full short-time withstand and selective coordination compliance. Category B breakers are mandatory in applications where upstream-downstream selectivity is required, ensuring only the breaker closest to a fault opens while upstream devices remain closed.
• Modular, Future-Ready Architecture – The MTZ platform supports digital modules that can be added or upgraded in the field. Install a Micrologic 5.0X today and upgrade to 6.0X or 7.0X capabilities tomorrow via firmware and module swaps — protecting your capital investment across decades of service.
• 1000V Insulation Rating – With a rated insulation voltage of 1000V and 12kV impulse withstand, the MTZ2-40 H1 is suitable for specialized applications including photovoltaic DC switchboards, large UPS systems, and industrial drives where elevated voltages may be present.
• Comprehensive Protection Functions – Long-time (L), short-time (S), instantaneous (I), and ground fault (G) protection curves are fully configurable via the Micrologic display or connected software. Energy-based tripping algorithms reduce nuisance trips from motor inrush while maintaining equipment safety margins.

Industrial Applications for the Schneider MTZ2-40 H1

The Schneider MTZ2-40 H1 4000A air circuit breaker serves as the cornerstone protection device in power distribution architectures across multiple heavy industries. Its combination of high continuous current rating, exceptional breaking capacity, and intelligent digital features makes it the preferred choice for:

Marine & Offshore Power Distribution

Onboard ship main switchboards, offshore platform power centers, and drilling rig electrical systems, the MTZ2-40 H1 provides reliable main incoming protection. The 66kA breaking capacity handles the high fault levels typical of marine generator sets (typically 2-6MVA), while the Micrologic 6.0X enables remote monitoring from the ship's automation system via Modbus or IEC 61850 protocols. Marine classification societies including DNV, Bureau Veritas, and Lloyd's Register recognize Masterpact breakers for type-approved installations.

Data Center & Critical Facility Infrastructure

Hyperscale and colocation data centers require ACBs that deliver both physical reliability and digital intelligence. The MTZ2-40 H1 protects UPS input feeders, transformer secondaries, and bus couplers in tier III/IV facilities. Its power quality monitoring functions track harmonic distortion and load balancing in real time  critical for environments where IT equipment represents millions of dollars in assets.

Industrial Manufacturing & Process Plants

Steel mills, cement plants, chemical processing facilities, and automotive manufacturing lines operate large motors, drives, and process heaters that demand robust switchgear. The 4000A rating supports large motor control center (MCC) incoming feeders, while Category B selectivity ensures coordinated fault isolation that minimizes production line shutdowns during electrical events.

Commercial & Healthcare Buildings

High-rise commercial towers, hospital complexes, and airport terminals utilize the MTZ2-40 H1 at the main distribution board (MDB) level. BACnet/IP communication enables direct integration with HVAC and lighting control systems, while energy metering functions support sustainability reporting and LEED certification requirements.

Renewable Energy & Microgrids

Solar PV farms, battery energy storage systems (BESS), and microgrid interconnection points benefit from the MTZ2's 1000V insulation capability and bidirectional current sensing. The Micrologic 6.0X can detect and protect against faults in both grid-tie and islanded operating modes.
