Frequently Asked Questions about 100-A18ND3
Question: What is the 100-A18ND3 used for?
Date Update:17/06/2025
Answer:

The 100-A18ND3 is a 3-pole IEC contactor rated for motor control and power switching applications. It is designed to control:

  • Three-phase motors
  • Resistive or inductive loads
  • Heaters, fans, or lighting circuits

The "D3" suffix indicates a DC coil control voltage, commonly 24V DC.

Question: What are the voltage and current ratings for the 100-A18ND3?
Date Update:17/06/2025
Answer:
  • AC-3 motor load rating: 18A @ 400–415V (approx. 5.5 kW / 7.5 HP)
  • AC-1 resistive load: 32A
  • Coil voltage: 24V DC (D3 designation)
  • Contact configuration: 3 Normally Open (NO) main contacts

Always confirm current ratings against the specific load type (AC-3, AC-1, etc.).

Question: What auxiliary contacts can be used with this contactor?
Date Update:17/06/2025
Answer:

You can attach:

  • Snap-on auxiliary contact blocks (e.g., 100-DFA22)
  • Top or side-mount options for additional NO/NC contacts
  • Timer blocks or interlocks depending on application

This flexibility makes it suitable for control schemes needing feedback or interlocking.

Question: Is the 100-A18ND3 field-replaceable or serviceable?
Date Update:17/06/2025
Answer:

Yes — coil and auxiliary modules are replaceable. However:

  • Main contacts are not field-serviceable
  • Replace entire contactor if contacts are damaged or worn
Question: What are the typical applications for the 100-A18ND3?
Date Update:17/06/2025
Answer:
  • Three-phase motor starters
  • Heating control panels
  • Pump or fan starters
  • Power switching in automation systems

It is commonly used in panels where space and modularity are required.
