NEMA Overload Relay 6-18 A
The SQUARE D 9065SF020 is a NEMA Size 0 electronic overload relay designed for three-phase motor protection. It provides a single normally-closed auxiliary contact for control-circuit signalling. The unit operates across a 6 A to 18 A current range with selectable Trip Class 10/20 and a 600 V AC maximum rating.
Separate Mounting for Motor Starters
This relay mounts separately from the contactor, leaving the starter assembly free for standard NEMA Size 0 dimensions. It requires the installer to supply appropriate thermal units or to pair it with compatible Series 9065 Motor Logic solid-state overload relays. Manual reset ensures a deliberate restart after a trip event.
For Maintenance and New Motor Circuits
Electricians and panel builders replacing a failed overload on existing NEMA Size 0 starters will find a direct functional match. Operations needing automatic reset, integrated thermal units, or a different auxiliary contact configuration should evaluate alternative relay styles.

Questions about this item
What is the maximum continuous current the 9065SF020 relay can handle before tripping?
The relay trips at a maximum current setting of 18 A, adjustable down to a minimum of 6 A.
How much heat does the electronic overload relay produce during all-day operation?
The solid-state design generates minimal heat compared to thermal units and mounts separately for easy dissipation.
Which contactor series must I already own to mount this overload relay?
It is compatible with Series 9065 Motor Logic Solid State Overload Relays for direct mounting.
