Eaton ECX09C1AHA-R63/B Nonreversing IEC Magnetic Motor Starter

SKU CH-MZ46-VX73F

A non-reversing IEC magnetic motor starter with electronic overload protection adjustable from 1 A to 5 A, selectable trip classes 10A, 10, 20, 30, three poles, two auxiliary contacts.

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Electronic overload protection with adjustable 1–5 A range
  • Selectable trip classes 10A, 10, 20, 30 for tailored motor protection
  • Three-pole IEC starter rated for 690 V AC supply
  • Two auxiliary contacts (1NO/1NC) included for control circuit integration
  • Hand/Off/Auto selector switch enables direct local operation

Industrial Motor Control

The Eaton ECX09C1AHA-R63/B is a non-reversing IEC magnetic motor starter designed for three-phase industrial applications. It features a selector switch with Hand/Off/Auto operator function for direct local control. The unit mounts on a surface and includes auxiliary contacts as standard.

Electronic Overload Upgrade

This starter replaces thermal overload models with an electronic overload relay offering a current setting range of 1 A to 5 A. The jump is worth it when adjustable trip classes of 10A, 10, 20, or 30 are required for precise motor protection. It supports a maximum voltage rating of 690V AC.

Three-Phase Panel Builders

The starter suits panel builders wiring three-pole motor circuits that need 1NO/1NC auxiliary contact blocks for status signalling. It is not for applications requiring reversing capability or overload settings beyond the 5 A maximum. Buyers needing different coil voltages or pole configurations should look elsewhere.

Questions about this item

What surface area does the 690V AC starter need for mounting?

The IEC motor starter uses surface mounting with a selector switch operator; allow clearance for the 3‑pole contactor and two auxiliary contacts when planning the panel layout.

Which step is often missed when wiring the 1‑5 A electronic overload?

Set the overload relay between 1 A and 5 A and choose the correct trip class — 10A, 10, 20 or 30 — before energising the three‑phase circuit.

When should the 1NO/1NC auxiliary contacts be inspected or replaced?

Check the auxiliary contacts during routine maintenance cycles; replace them if contact resistance rises or the hand/off/auto selector shows intermittent operation.
