Frequently Asked Questions about 1489-M1C100
Question: What is the 1489-M1C100 used for?
Date Update:16/06/2025
Answer:

The Allen-Bradley 1489-M1C100 is primarily used to protect electrical circuits from overcurrent conditions, such as short circuits or moderate overloads. Its 10A rating makes it ideal for standard load protection in control panels, machinery, and general-purpose industrial and commercial wiring systems. This MCB helps ensure equipment longevity and system safety by disconnecting power when current exceeds safe levels. Its reliability makes it a trusted choice for circuit designers and maintenance teams. It also helps meet UL, CSA, and IEC compliance in modern electrical installations.

Question: How to install the 1489-M1C100?
Date Update:16/06/2025
Answer:

Installation is a structured process:

  • Mount the breaker onto a standard DIN rail in the control panel.
  • Connect the incoming (line) and outgoing (load) wires to the top and bottom screw terminals.
  • Ensure correct torque settings for secure and vibration-resistant connections.
  • Confirm that the breaker’s rated voltage and current match the application’s requirements.
  • Test the mechanical operation of the breaker and label the circuit if required.

This simple but critical process ensures safety and functionality from the start.

Question: What does Trip Curve C mean?
Date Update:16/06/2025
Answer:

Trip Curve C describes the time-current characteristic of the breaker, where the unit trips between 5 and 10 times its rated current. This curve is ideal for protecting circuits with moderate inrush current, such as resistive loads or lightly inductive motors. It provides a balance between avoiding nuisance trips and offering fast disconnection during faults. This makes it suitable for lighting, HVAC equipment, or control devices. Curve C offers greater tolerance compared to Curve B, but isn’t as delayed as Curve D breakers.

Question: What is its short-circuit protection capability?
Date Update:16/06/2025
Answer:

The 1489-M1C100 offers a 10 kA interrupt rating at 240V AC, meaning it can safely clear fault currents up to 10,000 amps without damage. This rating meets the demands of high-energy industrial panels and ensures the safety of personnel and equipment. Always verify system fault capacity during breaker selection.

Question: Is the 1489-M1C100 still in production?
Date Update:16/06/2025
Answer:

Yes, the Allen-Bradley 1489-M1C100 is an active, current product. It remains a popular choice for panel builders and OEMs due to its compact size, high reliability, and compatibility with global standards. It is widely available and supported through Rockwell Automation's distributor network.
