Dayton 6ECA2 Overload Relay 63-80A Trip Class 10

63-80 A Overload Relay for Motor Protection

The Dayton 6ECA2 is a three-pole thermal overload relay designed to protect motors by interrupting the circuit when current exceeds the set threshold. It offers an adjustable trip range from 63 A minimum to 80 A maximum, suitable for industrial control panels and automation systems. The unit mounts directly to a contactor and complies with IEC 60947-4-1, CSA and UL Listed standards. Trip Class 10 provides a standard response time for general-purpose motor loads.

Thermal Operation and Power Characteristics

Thermal overload protection reacts to sustained overcurrent by heating an internal element, so the relay trips without external power or electronic sensors. Trip Class 10 defines the maximum tripping time at 7.2 times the current setting, giving predictable behaviour during motor start-up. The device carries both 1NO and 1NC auxiliary contacts for signalling or interlocking. Auto and manual reset modes let maintenance staff choose the recovery method after a fault.

Direct Contactor Mounting and Compliance Benefits

Direct-to-contactor mounting eliminates separate DIN-rail hardware and reduces panel wiring time. The compact body measures 4.29 in deep, 2.75 in wide and 2.12 in high, fitting tight enclosures. California Proposition 65 warnings apply because the product contains listed chemicals, a factor for installers in regulated jurisdictions. No additional accessories or software are bundled with this relay.
