9065TR0.55 - Square D Thermal Overload Relay

9065TR0.55 - Square D Thermal Overload Relay

Discover dependable motor protection in a compact package. The Square D 9065TR0.55 is a solid‑state thermal overload relay from Schneider Electric’s renowned Motor Logic (Class 9065) line. Designed for three‑phase motors with a full‑load current between 0.55–0.82 A, this device handles up to 600 VAC (and 300 VDC) and delivers ambient‑insensitive overload detection—making it perfect for HVAC equipment, pumps, conveyors, or OEM control panels 

Key Features and Benefits

• Precisely adjustable trip range (0.55–0.82 A): Ideal for small motor applications needing finely tuned overload protection.
• Accurate solid‑state detection: ±2% trip accuracy, with fast response and minimal sensitivity to ambient temperature fluctuations
• Ultra‑compact DIN‑rail design: At just about 0.55 lb (0.25 kg), it installs easily into tight panel spaces—even retrofitting existing NEMA Size 00–1 Type S starter setups.
• Built‑in auxiliary contacts: Includes one Normally Open (NO) and one Normally Closed (NC) contact for alarm or interlock wiring.
• Trip‑free self‑powered operation: Doesn’t require an external power source and will reliably cut power under fault—even if reset is pressed.
