SQUARE D 9065SFC20 Overload Relay
The SQUARE D 9065SFC20 is a NEMA overload relay designed for three-phase motor protection in industrial applications. It provides electronic overload protection with a current setting range of 3 A minimum to 9 A maximum. The unit features a 1NC auxiliary contact form and a manual reset type. It is rated for a maximum voltage of 600V AC and fits NEMA Size 00 starters.
Compatibility and Mounting Checks
Verify that the motor full-load current falls within the 3 A to 9 A adjustment range before ordering. Confirm the starter is a separately mounted NEMA Size 00 unit compatible with the 9065 Motor Logic series. Ensure the control circuit can accommodate a 1NC auxiliary contact for trip indication. The relay requires three thermal units which are not included with this device.
Sustained Load Behaviour
The relay operates with Trip Class 10/20 characteristics, meaning it will trip within a defined time under sustained overload conditions rather than instantaneously. Electronic overload protection monitors all three phases continuously to prevent nuisance tripping during normal start-up. Manual reset requires operator intervention after a trip event, ensuring the fault is investigated before restart. Separate mounting dissipates heat away from the starter during prolonged operation.

Questions about this item
Does the 9065SFC20 ship with thermal units or must they be ordered separately?
Thermal units are not included and the specification lists them as not applicable; this relay is designed for use with Series 9065 Motor Logic solid-state overloads.
Should I select the 3 A minimum or 9 A maximum current setting for my motor?
The relay is adjustable from 3 A to 9 A; set the dial to match the motor full-load current within that range.
What does the Trip Class 10/20 rating mean for motor protection?
Trip Class 10/20 means the relay will trip within 10 seconds at six times the set current for Class 10, or within 20 seconds for Class 20, providing overload protection suited to motor start-up characteristics.
