Schneider Electric 9065-SEO5 Thermal Overload Relay

The 9065-SEO5 is a CT-operated, three-pole melting-alloy thermal overload relay designed to protect motors in Square D/Schneider Electric 9065 starter circuits. This standalone, separately mounted device provides a normally closed (1NC) trip path and is aligned with NEMA Size 1 configurations. It is rated for up to 600 V (AC or DC) and supports a maximum current of 25 A, with trip-class options including Class 10 and Class 30, making it suitable for coordinated protection with the associated contactor in three-phase installations. As a replacement-style overload relay, the SEO5 is specified for use with Square D Class 9065 starters and related 8536-family equipment, delivering motor protection by interrupting the circuit when overload conditions are detected via its melting-alloy mechanism. The relay carries recognition for global use, being UL Listed, CSA Certified, and CE Marked, which simplifies cross-border applications. Its three-pole design ensures all three conductors are interrupted for effective protection, and its CT-operated sensing enables coordinated protection with appropriate motor control components in standard industrial applications such as fans, conveyors, pumps, and small to medium motors in machinery control systems.
