Siemens 3UA50 00-0E Overload Relay

The overload relay, also known as motor protection relay, thermal relay, or overcurrent relay, with type number 3UA50 00-0E from Siemens, is an electrical relay used to protect electric motors and circuits from overload. It has the dimensions 15 x 5 x 10 cm and weighs 0.2 kg. Overload relays protect electrical drives and systems from damage due to excessively high currents by interrupting the circuit when a set limit value is exceeded, thereby ensuring operational safety. Typical applications include the protection of pumps, fans, and conveyor systems in mechanical engineering as well as in complex automation systems.
