Relay range and trip class

The Dayton 6ECC5 overload relay provides thermal protection for three-phase circuits with an adjustable current range from 12 A to 18 A. It conforms to IEC 60947-4-1 and carries CSA and UL Listed approvals. Trip class 10 ensures a standard response time for motor overload conditions.

Contacts and reset options

The unit includes one normally open and one normally closed auxiliary contact for signalling or control wiring. Both automatic and manual reset modes are available, allowing the installer to choose the recovery method that suits the application.

Direct contactor mounting

A direct-to-contactor mounting style reduces panel space and wiring effort during assembly. The transparent housing allows visual inspection of the mechanism. Overall dimensions are 2.5 in height, 1.73 in width and 3.62 in depth. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

How often should the thermal overload element in this 12-18 A relay be inspected or replaced?

The thermal overload protection uses a Trip Class 10 design with auto and manual reset options. No scheduled replacement interval is defined; inspect contacts after any trip event and replace the unit if the mechanism fails to reset cleanly.

What stops the relay from carrying more than its 18 A maximum setting during continuous operation?

The maximum overload relay current setting is 18 A. When sustained current exceeds this value the thermal element trips to protect the downstream circuit.

How much heat does the relay dissipate when mounted directly to a contactor and run all day at full load?

The IEC-style body measures 3.62 in deep, 1.85 in high and 1.73 in wide. Heat dissipation varies with the actual load current and ambient temperature; ensure the enclosure provides adequate airflow around these dimensions.
