SQUARE D

SQUARE D 9065SF120 NEMA Overload Relay 1NC 9-27A

SKU CH-N7XV-S0DR8

NEMA overload relay protects three-phase motors with a 9–27 A electronic trip range and 1NC auxiliary contact

  • Protects motors across a 9–27 A range with adjustable electronic overload
  • Trip Class 10/20 provides fast overload response for critical machinery
  • Three-pole 600 V AC rating suits industrial power systems
  • 1NC auxiliary contact enables direct control-circuit signalling
  • Separately mounted NEMA Size 1 design fits existing Series 9065 installations

SQUARE D 9065SF120 NEMA Overload Relay

This SQUARE D 9065SF120 is a NEMA-rated electronic overload relay designed for three-phase motor protection. It provides adjustable current monitoring with a manual reset function for industrial machinery applications. The unit mounts separately and fits Series 9065 Motor Logic solid-state systems. It operates at up to 600V AC across three poles.

Suited for NEMA Size 1 motor starters needing

Engineers specifying NEMA Size 1 starters with a 9 A to 27 A current range will find this relay matches the required Trip Class 10/20 profile. The single normally closed auxiliary contact supports standard control-circuit signalling. Buyers who need a broader current range or automatic reset capability should look at alternative devices.

Adjustable 9 A to 27 A electronic trip range

The decisive specification is the electronic overload protection adjustable between 9 A minimum and 27 A maximum current settings. This range determines whether the relay matches the motor full-load current for NEMA Size 1 applications. Trip Class 10/20 timing and 600V AC rating complete the core selection criteria.

Questions about this item

Which contactor or starter must I already have to mount this 9065SF120 overload relay?

This NEMA Size 1 relay is designed for separate mounting and is compatible with Series 9065 Motor Logic solid-state overload relays, so you need a matching NEMA Size 1 contactor or starter that accepts a separately mounted overload.

Will the 9 A to 27 A adjustment range cover the motor I currently run on an older NEMA Size 1 starter?

Yes, the relay adjusts from 9 A minimum to 27 A maximum, matching the full-load current of many motors used with NEMA Size 1 starters, and its Trip Class 10/20 suits standard and heavy-starting loads.

How can I verify the relay is protecting the circuit correctly after wiring it?

Apply load current within the 9 A to 27 A range; the relay should trip on overload according to Trip Class 10/20 timing, the 1NC auxiliary contact will open to signal the trip, and the manual reset button must be pressed to restore operation.
