SQUARE D 9065SFB20 NEMA Overload Relay 1NC 1.5-4.5A Trip Class 10/20 600V AC

SKU CH-6BE6-75TH8

NEMA overload relay protects three-phase motors with a 1.5–4.5 A electronic trip range, Class 10/20 timing and 600 V AC rating

  • Protects motors with 1.5 A to 4.5 A adjustable range
  • Trip Class 10/20 gives fast overload response
  • 600 V AC rating suits industrial power systems
  • Manual reset ensures deliberate restart after fault
  • Three-pole NEMA Size 0 design fits standard starters

Industrial Motor Protection

The SQUARE D 9065SFB20 is a NEMA overload relay built for three-phase motor circuits up to 600V AC. It suits maintenance teams and panel builders who need reliable electronic overload protection in a separately mounted package.

Adjustable 1.5-4.5A Range with Dual Trip Class

The relay handles motors drawing between 1.5 A and 4.5 A and offers selectable Trip Class 10 or 20 for matched thermal response. It covers NEMA Size 0 applications but cannot protect loads outside this current window or voltages above 600V AC.

Replaces Thermal Block Overloads on Series 9065

This unit upgrades legacy thermal-block overloads on compatible Series 9065 Motor Logic starters, adding electronic sensing and manual reset. The jump is worthwhile when an application demands adjustable trip classes and solid-state reliability instead of fixed thermal elements.

Questions about this item

Will the 9065SFB20 overload relay work with my existing NEMA Size 0 contactor?

Yes, this relay is a NEMA Size 0 device designed for separate mounting and is compatible with Series 9065 Motor Logic solid-state overload relays.

How can I verify the relay trips correctly after installation?

Set the dial between 1.5 A and 4.5 A for your motor load; the Trip Class 10/20 rating means it will open the 1NC contact within the standard time curve for that class.

Does the 9065SFB20 come with thermal units or must I buy them separately?

Thermal units are not applicable for this electronic overload relay, so nothing extra is required for basic operation.
