Dayton 6ECA7 Overload Relay 0.63-1 A 1NC/1NO

SKU CH-GDVR-QSWC1

Thermal overload relay protects motors from 0.63 A to 1 A with auto or manual reset

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Thermal overload protection trips at 0.63–1 A
  • Trip Class 10 meets IEC 60947-4-1 standard
  • Auto and manual reset modes for flexible recovery
  • Direct-to-contactor mounting saves panel space
  • UL Listed and CSA certified for safety compliance

Application & fit

The Dayton 6ECA7 is a thermal overload relay designed for industrial motor-control panels. It protects three-phase circuits by interrupting the contactor coil when current exceeds the set threshold, making it suitable for maintenance engineers and panel builders wiring IEC-style starters.

Current range & trip class

The adjustable dial covers 0.63 A to 1 A and the unit carries a Trip Class 10 rating to IEC 60947-4-1. One normally-open and one normally-closed auxiliary contact provide status feedback to the control circuit.

Thermal behaviour & mounting

The relay mounts directly to the contactor and dissipates heat through its 3.62 in deep body without forced airflow. Auto and manual reset modes are selectable, and the device is UL Listed and CSA certified for panel use.

Questions about this item

What does the 1 A maximum current setting mean when the relay is installed in a motor circuit?

It means the relay will trip to protect the motor if the current exceeds 1 A, with a minimum setting of 0.63 A for finer adjustment.

How does the IEC 60947-4-1 standard affect the way this overload relay operates?

The relay complies with IEC 60947-4-1, CSA and UL Listed requirements, ensuring its thermal trip Class 10 performance meets recognised industrial safety and coordination rules.

What are the physical dimensions I need to allow for direct contactor mounting?

The relay body measures 1.73 in wide, 1.85 in high and 3.62 in deep, with an overall height of 2.5 in when mounted directly on the contactor.
