1YMB531029M0003 ABB High Voltage Fuse Link

Product Dimensions：

Product Overview

The 1YMB531029M0003 belongs to the CMF (Current Limiting Motor Fuse) series, which are specialized high-voltage fuses. These fuses are characterized by their ability to limit the peak current during a short circuit event, thereby reducing the stress on upstream and downstream equipment. They are designed with an “overload spot” using the M-effect, which ensures precise and reliable operation for both overload and short-circuit conditions.

Product Parameters

• Manufacturer Part Number: 1YMB531029M0003
• Series: CMF (Current Limiting Motor Fuse)
• Rated Voltage: 7.2 kV
• Rated Current: 160 A (Note: Some sources may indicate variations, but 160A is consistently associated with this part number in specific documentation for the CMF series at 7.2kV)
• Dimensions:
  • Length: 442 mm
  • Diameter: 65 mm (for this specific current rating, diameter can vary for other CMF fuses)
• Standards: Tested according to IEC Publication 60282-1 (IEC 282-1) and IEC Publication 644 (IEC 644). IEC 644 specifically applies to fuse links used with direct-on-line started motors in AC systems.
• Mounting: Designed for indoor use.
• Weight: Approximately 3.0 kg (Weight can vary slightly for different current ratings within the CMF series).

Product Advantages

• Excellent Motor Starting Withstand Capability: Specifically designed and tested (IEC 644) to withstand the repeated current surges associated with motor starting without deterioration, ensuring long operational life.
• High Current Limiting Capability: Limits the magnitude of prospective short-circuit currents, reducing mechanical and thermal stress on protected equipment and extending their lifespan.
• Low Minimum Breaking Current: Capable of interrupting low fault currents effectively, which widens the protection range.
• Low Power Losses: Efficient design leads to reduced energy waste and allows for installation in more compact switchgear compartments, as less heat is generated.
• “M-Effect” Technology: Utilizes an overload spot on the fuse elements, created by coating silver fuse elements with a low melting point metal. This technology ensures an extended operational range and reliable fusing for small overload currents, and ensures arc initiation at a consistent, safe point.
• High Breaking Capacity: Ensures effective interruption of high fault currents.
• Reduced Overvoltages: Designed to generate low arc voltages during interruption, minimizing stress on the insulation of the protected circuit.

Precautions

• Installation by Qualified Personnel: High voltage equipment requires specialized knowledge and training. Installation, maintenance, and replacement should only be carried out by certified and experienced electrical personnel following all local and international safety regulations.
• De-energize Before Work: Always ensure that the circuit is completely de-energized and locked out before attempting any work on the fuse or associated equipment.
• Correct Selection: Verify that the fuse’s rated voltage, current, and breaking capacity are suitable for the specific application and system parameters. Mismatched fuses can lead to dangerous failures.
• Environmental Conditions: Ensure the fuse is installed in an environment within its specified operating temperature and humidity ranges.
• Physical Handling: Handle fuses carefully to avoid physical damage, which could compromise their integrity and performance.
• No Repair or Regeneration: Fuse links are single-use protection devices and cannot be repaired or regenerated after they have operated. They must be replaced with an identical or approved equivalent.
• Refer to Documentation: Always consult the official ABB product documentation, datasheets, and installation manuals for precise specifications, installation instructions, and safety guidelines.
