Siemens ITE Overload Relay Switch 600V AC MAX Overload Relay Switch

Siemens overload relay switch is a motor-protection device that works with Siemens contactors to monitor running current and trip on overload. It is rated for up to 600 V AC maximum, enabling use in a wide range of industrial motor circuits. The lineup includes models with adjustable current settings, such as 3UA50-00-1G, which provides a 4–6.3 A range at 600 V max, and other variants that cover higher currents (for example 5.5–8.0 A in size S00 with Class 10) designed for stand-alone installation or mounting on the main circuit side of a contactor. These relays utilize a thermal overload release mechanism and offer dependable wiring through screw-terminal or box-lug connections for the main and auxiliary circuits, giving flexible protection options in control panels and motor circuits.
