Industrial Overload Relay 0.40-0.63 A

The Dayton 6ECA6 is a three-pole thermal overload relay designed for direct contactor mounting in industrial motor circuits. It operates within a current range of .40 to .63 A and carries IEC 60947-4-1, CSA and UL certifications. The unit features both automatic and manual reset options with a Trip Class 10 response.

Suited for motor-starter panels needing IEC-style

This relay fits panels where a compact IEC-format device with 1NO/1NC auxiliary contacts is specified. It is not for applications that require a NEMA-rated frame, electronic trip units or current settings outside the .40-.63 A window. Buyers needing higher current ranges or different auxiliary configurations should look elsewhere.

Verify contactor compatibility and panel space

Confirm that the contactor model accepts direct-mount IEC relays and that the .40-.63 A range matches the motor full-load current. The body measures 3.62 in deep, 1.85 in high and 1.73 in wide with an overall height of 2.5 in. Ensure the enclosure provides adequate clearance for wiring and the reset mechanism.

Questions about this item

What contactor does the 6ECA6 overload relay mount to directly?

The relay uses a direct-to-contactor mounting style, so it attaches to a compatible IEC contactor without extra brackets.

Will the 0.40–0.63 A trip range coordinate with a legacy motor starter wired for Trip Class 10?

Yes, the relay is rated Trip Class 10, matching the timing curve of older Class 10 starters in the same current band.

After wiring the 1NO/1NC auxiliary contacts, how can I confirm the relay trips at the set current?

Apply load current above 0.63 A; the thermal element should open the NC contact and close the NO contact within the Class 10 time curve.
