Overload Relay 0.16-0.25 A

The Dayton 6ECA4 is a thermal overload relay designed for industrial motor protection in IEC applications. It provides adjustable overload protection for circuits drawing between 0.16 A and 0.25 A. The unit mounts directly to a contactor and meets IEC 60947-4-1, CSA, and UL Listed standards. It suits maintenance engineers and panel builders managing low-current motor starters.

Compatibility Check Before Ordering

Verify that your contactor accepts direct-mount IEC-style relays and that the motor full-load current falls within the 0.16 A to 0.25 A range. Confirm the control circuit can accommodate the 1NO/1NC auxiliary contact configuration for signalling. The Trip Class 10 characteristic must match your coordination requirements. Ensure the 3.62 in body depth fits within your enclosure layout.

Bundled Features And Impact

The relay includes both auto and manual reset modes, allowing flexible restart policies after a trip event. The 1NO/1NC auxiliary contacts enable remote status indication or interlocking without extra components. A transparent cover lets operators inspect the setting dial and trip indicator visually. These integrated features reduce panel wiring time and simplify commissioning.

Questions about this item

What comes in the box with the Dayton 6ECA4 overload relay and what must be purchased separately?

The relay itself is supplied; a compatible IEC contactor for direct mounting and any required wiring or DIN-rail hardware are not included.

Which current setting should I select between the 0.16 A minimum and 0.25 A maximum?

Set the dial to the full-load current of the motor you are protecting; the adjustable range covers 0.16 A to 0.25 A.

What does the Trip Class 10 rating mean for actual motor protection?

The relay will trip within 10 seconds at six times the set current, providing standard thermal overload protection for general-purpose motors.
