Square D 9065SEO8 Thermal Nema Overload Relay 600V Nema 2

Product Description

The SQUARE D 9065SEO8 is a thermal NEMA overload relay rated for 600 VAC service at NEMA Size 2. It protects three-phase and single-phase motor starters from sustained overcurrent conditions by sensing heat buildup through a thermal element, tripping the contactor before motor windings sustain damage. Licensed electricians and industrial maintenance technicians install this relay as part of a motor control assembly. The thermal sensing method provides reliable, time-delay overload protection suited to the inrush characteristics of induction motors in commercial and industrial applications.

This overload relay is designed for motor control centers, combination starters, and panel-mounted starter assemblies operating at voltages up to 600 VAC. It is appropriate for both new installations and replacement service on existing NEMA motor starters where the OEM overload element has worn or tripped beyond reset. The NEMA Size 2 rating corresponds to motor starters in the common range for commercial HVAC equipment, pumping systems, and light industrial machinery.

Key Features

• Thermal sensing method provides automatic time-delay overload protection for motor windings
• Rated to 600 VAC for compatibility with standard North American industrial voltage systems
• NEMA Size 2 form factor fits corresponding NEMA motor starters and control assemblies
• Compact body measuring 4.7 inches tall, 5.2 inches wide, and 5.3 inches in length
• Sold as a single unit — direct drop-in replacement for field service calls

Compatibility

Designed as an OEM-style replacement thermal overload relay for NEMA Size 2 motor starter assemblies rated up to 600 VAC.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the motor control panel before removing or installing the overload relay. Verify that the replacement relay matches the heater element range required for the connected motor full-load amperage before restoring power. Do not attempt to reset a tripped relay without first identifying and correcting the overload condition.
