The Siemens 3US5200-2C8K is a reliable bimetal thermal overload relay designed for dependable three-phase motor protection in industrial motor control applications. With an adjustable current range of 16–25A, this Siemens overload relay helps protect motors against sustained overload conditions that can cause excessive heating and premature motor failure.
Designed in size S1 with a Class 10 tripping characteristic, the relay is suitable for motors with standard starting conditions. Its bimetal thermal protection principle responds to prolonged overcurrent and helps disconnect the motor control circuit through the associated starter arrangement before excessive heating causes damage.
The Siemens 3US5200-2C8K is suitable for motor starters, industrial control panels, pumps, fans, conveyors, machinery, and other motor-driven equipment requiring dependable overload protection.
