9065TR5.5 - Square D Thermal Overload Relay

9065TR5.5 - Square D Thermal Overload Relay

The Square D 9065TR5.5 thermal overload relay delivers dependable protection for motors in industrial and commercial settings. Designed as part of Schneider Electric’s 9065 Motor Logistics lineup, this relay helps prevent motor damage by interrupting current at just the right time. It’s a wise choice for applications in HVAC systems, pumps, compressors, conveyors—and anywhere motor performance and safety are top priorities.

Key Features and Benefits

• Adjustable trip range (5.5 A to 8.3 A): Fine‑tune overload protection to match motor specs, especially effective in mid‑sized motor control systems.
• Solid‑state bimetallic mechanism: Reacts quicker to overloads than traditional melting alloys, offering dependable motor safety.
• Continuous‑duty rating: Built to operate without overheating even in high‑use environments.
• Bolt‑on mounting for NEMA Size 0/1 starters: Space‑efficient and easy to install in starter panels or compact control cabinets.
• Good trip accuracy at 125% of dial setting: Safeguards against error‑triggering while still preventing motor burnout.
• Rugged polyester housing & cadmium‑plated contact surfaces: Suitable for harsher industrial environments without compromising performance.
