Benshaw SPO-22-7.5 Overload Relay Switch

The Benshaw SPO-22-7.5 Overload Relay is a Class 10, bimetallic overload protection device in the SPO series, designed to provide thermal protection for motors controlled by Benshaw contactors. It carries a nominal current rating of 7.5 A and supports a protection range of 6.0–9.0 A, enabling reliable trip sensing within typical operating currents. Engineered for direct mounting to compatible Benshaw contactors—including RSC-series units—the SPO-22-7.5 integrates into a compact protection assembly for motor-control panels. As part of Benshaw's low-voltage protection lineup, this relay delivers the deterministic Class 10 trip characteristics expected from SPO-series devices and serves as a straightforward, integrated motor-protection option in applications where space and simplicity matter. The model designation reflects its SPO-22 family placement and 7.5 A nominal capacity, making it suitable for protecting motors and related control circuits in industrial equipment that rely on Benshaw RC/RSC contactors.
