• Safety Protection: Equipped with multiple protection functions including overload, short-circuit, undervoltage, and overvoltage, complying with IEC 61800‑9‑2 safety requirements.

Structure and Composition

• Enclosure: Die-cast metal enclosure providing dust and water protection (IP20 rating).
• Circuit Breaker Body: Includes contacts, spring mechanism, and thermal-magnetic overload components.
• Operating Mechanism: Manual/electric operating handle with indicator lights to show operational status.
• Terminal Blocks: Screw-type terminal blocks for easy on-site wiring.
• Accessories: Optional current transformers, auxiliary contacts, remote monitoring modules, etc.

Typical Application Fields

• Industrial Power Distribution: Main power distribution branches in large manufacturing workshops and processing plants.
• Motor Control Centers (MCC): Drives high-power motors such as pumps, compressors, and conveyors.
• Energy Systems: Front-end protection for generator sets and variable frequency drive systems.
• Building Facilities: Power distribution feeder buckets and equipment room power management in large buildings.

Installation and Maintenance Guidelines

• Pre-installation Inspection: Verify that the on-site voltage level and short-circuit current capacity match the product specifications.
• Fixing Method: Secure the circuit breaker to the distribution cabinet or bracket with bolts to ensure horizontal and vertical alignment.
• Wiring: Use wires compliant with IEC 60364 standard and check contact resistance after tightening terminals.
• Commissioning: Perform insulation resistance test before power-on, followed by overload setting and short-circuit breaking capacity verification.
• Routine Maintenance: Inspect contact wear, spring tension, and terminal tightness every 6 months; replace the circuit breaker or accessories if necessary.
• Fault Diagnosis: Use indicator lights and remote monitoring modules to quickly locate abnormalities such as overload, short-circuit, or undervoltage.
