Eaton ECX09C1CHA-R63/B Motor Starter

The Eaton ECX09C1CHA-R63/B is a non-reversing IEC magnetic motor starter rated for 690V AC three-phase supply. It handles a maximum overload relay current setting of 5 A and includes 1NO/1NC auxiliary contacts. This unit suits industrial control panels that need electronic overload protection with selectable trip classes of 10A, 10, 20 or 30.

Surface-Mount Installation Notes

The starter uses surface mounting and a Hand/Off/Auto selector switch for local operator control. Wiring must follow the three-pole layout and the auxiliary contact form shown in the documentation. Incorrect trip-class selection or loose auxiliary terminals are the most common issues during commissioning.

Pre-Order Compatibility Check

Verify that your control voltage matches the coil requirements and that the 5 A maximum overload setting covers the motor full-load current. Confirm the panel has space for a surface-mount IEC starter and that the 1NO/1NC auxiliary contact arrangement fits your control circuit logic.

Questions about this item

How do I confirm the starter is working after wiring it to a 690V AC three-phase supply?

Verify the Hand/Off/Auto selector moves through all three positions, the overload relay trips within the 1 A to 5 A range at the chosen Trip Class 10A/10/20/30 setting, and the 1NO/1NC auxiliary contacts change state as the contactor operates.

What comes in the box and what must I source separately?

The starter ships complete with the IEC contactor, electronic overload relay adjustable from 1 A to 5 A, 1NO/1NC auxiliary contacts and Hand/Off/Auto selector switch mounted in a surface-mount enclosure; supply conductors, branch-circuit protection and control-circuit wiring are not included.

Which overload setting should I choose for a 63 A motor load?

Select a Trip Class — 10A, 10, 20 or 30 — that matches the motor’s acceleration time, then set the electronic overload dial between 1 A and 5 A; the 63 A rating is the contactor’s maximum operational current, not the overload adjustment range.
