Siemens Bimetal Motor Protector 3RV2041-4HA10, 36–50 A

The Siemens 3RV2041-4HA10 is a bimetal motor protector designed for thermal protection of electric motors. It covers an operating current range of 36 to 50 amperes and features a 0–1 manual switch for on/off control. This device ensures reliable overload and phase-failure protection in industrial motor circuits, helping to extend motor life and prevent damage. Typical applications include conveyors, pumps, fans, and other machinery where motor protection is essential. The bimetal design provides a delayed trip response proportional to the overload magnitude.
