Square D 9065S Type S Melting Alloy Overload Relay, NEMA Size 2, 600VAC

The Square D 9065S Type S Melting Alloy Overload Relay is a Motor Logic overload relay designed as a standalone device or for use on Type S full voltage non-reversing and reversing starters and combination starters. Rated NEMA Size 2 with a 600VAC (Ue) operational voltage rating for 3 phase, 50/60 Hz motor circuits, this melting alloy relay is available across a Motor FLA range of 3A to 45A depending on the thermal unit and configuration selected, letting maintenance teams match overload protection to the exact full-load amperage of the motor being protected. The relay is ambient insensitive and self-powered, delivering consistent thermal protection for costly motor-driven equipment without the need for external control power.

Key Features

  • NEMA Size 2: Sized configuration for coordinated motor overload protection.
  • Motor FLA Range: Available in Motor FLA ratings from 3A up to 45A to match a wide range of motor full-load amperage requirements.
  • Melting Alloy Technology: Ambient insensitive, self-powered thermal overload sensing for reliable trip performance.
  • 600VAC Rated Operational Voltage: Ue rating supports 3 phase, 50/60 Hz motor circuits.
  • Field Interchangeable Thermal Units: Requires 3 thermal units per relay for replacement motor installations.
  • Flexible Mounting: Available as direct mount or separate mount, with mounting plate support.
  • Starter Compatibility: Standard on non-reversing, reversing, combination, and multispeed starters.
  • Simple Installation: Straightforward setup for maintenance and replacement work.

Square D 9065SDO5 – Frequently Asked Questions

1) Do I need to order thermal units separately with the Square D 9065S Type S overload relay?
Yes. The Type S melting alloy relay takes 3 thermal units, and they are field interchangeable. On a replacement motor installation you size the thermal units to the new motor's full load amps, so budget three units per relay on top of the relay itself.
2) What motor full load amp ratings does the Square D Type S NEMA Size 2 overload relay cover?
Three build-outs are offered by motor FLA: 3A (9065SFC20), 27A (9065SDO5) and 45A (9065SDO8). Match the relay to the nameplate FLA of the motor you are protecting.
3) Will this relay work as a standalone overload, or does it have to be mounted on a Square D starter?
Either. It is designed as a standalone device or for use on Type S full voltage non-reversing and reversing starters and combination starters. Mounting is flexible, direct mount or separate mount with mounting plate support, so it drops into an existing control panel without a starter body.
4) Does a melting alloy overload relay need external control power or ambient temperature compensation?
No. The melting alloy design is ambient insensitive and self-powered, so it senses motor heating without a separate control power source and does not shift trip point with panel temperature. That is the practical difference from a bimetallic or electronic overload that relies on compensation or control voltage.
5) Is the Square D Type S NEMA Size 2 relay right for a multispeed or reversing starter assembly?
Yes, it is standard on non-reversing, reversing, combination, and multispeed starters. Note that a multispeed assembly normally needs overload protection on each speed winding, so count the relays by winding, not by motor.
6) What does NEMA Size 2 mean when I am matching this overload relay to my existing starter?
NEMA Size 2 is the starter frame size the relay is built to coordinate with, so it pairs with a Size 2 Type S starter and its contactor. If the starter in your panel is a Size 1 or Size 3, this relay is the wrong frame even if the motor FLA looks close.
7) Is the Square D 9065S overload relay RoHS compliant, and where is it made?
RoHS compliant and mercury free, built in Mexico by Schneider Electric. It is also within scope of the EU WEEE collection requirements, which matters if you are specifying for a facility with take-back reporting.
