SQUARE D
SQUARE D 9065SF220 NEMA Overload Relay 15-45 A 600 V
Protects three-phase motors with electronic overload detection from 15 to 45 amps at 600 volts AC
- Protects motors from 15 A to 45 A overloads with adjustable electronic sensing
- Trip Class 10/20 selects fast or standard thermal response for application flexibility
- Handles three-phase loads up to 600 V AC for industrial voltage compatibility
- Manual reset ensures deliberate restart after fault clearance for operator safety
- Separately mounted NEMA Size 2 design fits existing 9065 Motor Logic starter assemblies
SQUARE D 9065SF220 NEMA Overload Relay
This SQUARE D 9065SF220 is a NEMA overload relay rated for 600 V AC and NEMA Size 2. It provides electronic overload protection for three-phase motors with a current setting range of 15 A to 45 A. The unit mounts separately and includes a 1NC auxiliary contact for control circuits. Manual reset is required after a trip event.
Suits panels using Series 9065 Motor Logic relays
Electricians wiring motor starters that accept separately mounted NEMA Size 2 relays will find this unit compatible. It covers Trip Class 10/20 applications where a 15 A to 45 A adjustment range is specified. Panels requiring a different NEMA size, automatic reset, or a voltage rating above 600 V AC cannot use this relay.
Current range 15 A to 45 A
The adjustable setting span of 15 A minimum to 45 A maximum is the single figure that determines whether this relay matches the motor full-load current. If the motor nameplate current falls outside this window, the relay will not protect the circuit correctly. Verify the motor amperage before selecting this part.

Questions about this item
What mounting style does the 9065SF220 overload relay use?
The relay is separately mounted and does not attach directly to a contactor, so you will need panel space and appropriate hardware for a stand-alone installation.
How do you reset the relay after a trip, and what is the common mistake?
Reset is manual; the step people miss is waiting for the thermal elements to cool before pressing the reset button, otherwise the relay will trip again immediately.
Does the 9065SF220 include thermal units, and what maintenance does it need?
Thermal units are not included and are not applicable for this electronic overload; maintenance consists of periodic inspection of the 1NC auxiliary contact and verification that the 15-45 A setting matches the motor load.
