1. Overview

2. Key Technical Specifications

• Rated Current: 200A
• Number of Poles: 3P (3-pole)
• Rated Voltage: 415V AC (400V AC optional)
• Short-Circuit Breaking Capacity: Complies with the corresponding class of IEC 60947-2 (commonly 10kA–25kA)
• Wiring Method: Frame-type (BT) + Neutral Terminal (NA)
• Dimensions: Standard NZM series dimensions, with only four compact specifications covering all application scenarios
• Compliance Certifications: UL, CSA, IEC 60364, EN 60947-2

3. Product Features

• Modular Function Groups: Flexibly combine protection functions such as thermal-magnetic, overload, undervoltage, and undercurrent according to on-site needs.
• Compact Structure: Four sizes meet the requirements from small distribution cabinets to large power distribution stations, saving space.
• Global Applicability: Complies with both UL/CSA and IEC standards, facilitating unified procurement for cross-border projects.
• Adjustable Overload Protection: The thermal-magnetic release allows adjustment of overload current (Ir) to meet different load characteristics.
• Reliable Mechanical Life: High-strength alloy housing and corrosion-resistant terminals ensure adaptability to harsh industrial environments.

4. Structure and Composition

• Main Body: Metal housing, internal mechanical release mechanism, and thermal-magnetic release.
• Terminals: Frame-type (BT) terminals for phase wires and NA neutral terminal for neutral wires.
• Function Modules: Optional protection modules (thermal-magnetic, undervoltage, undercurrent, instantaneous overcurrent, etc.) that can be quickly plugged and unplugged on-site.
• Indicators/Display: Status indicators show the circuit breaker’s operating, fault, or manual operation status.

5. Typical Application Fields

• Industrial Distribution Cabinets: Main power distribution for production lines, mechanical equipment, and automation systems.
• Building Electrical and Mechanical Systems: Power distribution branches in large commercial buildings and office buildings.
• Energy Facilities: Front-end protection for substations, photovoltaic inverters, and wind turbines.
• Transportation Facilities: Power distribution protection for public facilities such as subways, light rail, and airports.
• Process Control Systems: High-reliability power distribution needs in industries such as chemical, metallurgy, and papermaking.

6. Installation and Maintenance Guidelines

• Pre-installation Inspection: Confirm that the rated voltage and current match on-site requirements; check the integrity of terminals.
• Wiring Method: Use frame-type (BT) terminals for phase wires and NA neutral terminal for neutral wires, ensuring correct phase sequence.
• Function Module Configuration: Select thermal-magnetic, undervoltage, or undercurrent modules based on load characteristics, and adjust the overload current setting (Ir).
• Mechanical Fixing: Secure the circuit breaker to the distribution cabinet or guide rail with special bolts to prevent loosening due to vibration.
• Regular Inspection: Conduct external and terminal tightening inspections every 6 months; perform functional tests (overload, undervoltage, etc.) every 12 months.
• Fault Diagnosis: Use indicators or handheld testers to quickly locate fault points and replace corresponding function modules if necessary.
• Safety Measures: Ensure power is cut off and qualified protective equipment is worn before operation, following IEC 60947-1 safety standards.
