Siemens 3UA7021-1C Overload Relay

The overload relay, also known as motor protection relay or thermal overload relay, from Siemens with type number 3UA7021-1C is an electrical relay for protecting motors and systems against overload. It is designed for a current range of 1.6 to 2.5 A. It has the dimensions 8 x 9 x 8 cm and weighs 0.1 kg. Overload relays serve to protect electrical motors and systems from damage due to overcurrent by interrupting the circuit when a defined current value is exceeded. Typical applications include control technology for pumps, fans, conveyor belts, and machine tools, to extend their lifespan and minimize downtime.
