Solid-State Overload Relay

The Sirius 3RB10 IEC solid-state overload relay offers ease of installation and service and provides end-users with savings in space and time. It comes with an array of standard features, including phase loss protection, 4:1 adjustment range, Class 10 or Class 20 trip protection and heaterless design to reduce heating in panels.

All models have an overload temperature rating of –30°C to 70°C, and are available in rating from 0.1 to 100 A (suitable for 50/60 Hz). The modular system is comprised of four sizes up to 100 hp at 600V, and in three widths (45, 55 and 70 mm), meeting all requirements for starting, stopping and protecting motors. All components can be "butt-mounted" in dense arrays without de-rating in ambient temperatures up to 140°F.
