Square D 9065SF020U Industrial Control Contactor

Square D 9065SF020U is a solid-state overload relay (Motor Logic) from Square D designed for three-phase motor protection in a separate-mount configuration. This NEMA Size 0 device protects 3‑phase loads rated 6 to 18 A and supports circuits up to 600 VAC, making it suitable for a wide range of industrial motors. Designed to work with Square D Type S contactors and starters, it complements compact motor-control assemblies by adding reliable overload protection without a built-in coil. The unit’s 3‑pole construction and 600 VAC rating enable integration into standard Square D control panels, conveyors, pumps, fans, and other equipment where precise current-based protection is essential. With a dedicated overload relay, technicians can replace or upgrade protection without altering the main contactor, preserving system integrity during maintenance. Key specs include 3‑pole configuration, 6–18 A protection range, 600 VAC maximum, NEMA Size 0 housing, and a separate-mount design that simplifies wiring and field retrofits in existing installations.
